Crucial to the cooperation with cus-tomers are the consultancy services provided by the competence centre at the Witzenmann headquarters in Pforzheim, southern Germany. Teams of highly qualified engineers working side by side with the customer on product developments and new expansion joint applications. Special-ists complementing the customer’s skills. From the preliminary drawings to large-scale production.
Technically CompetentThis concentration of knowledge forms a foundation for the synergy is evident in every product, every solution. Our Products have an almost unlimited and diverse range of application but all have one thing in common – maximum safety even in the most extreme appli-cations. This is true of all Witzenmann solutions whether a highly flexible hose or an expansion joint is specified.
Skilled solutionsWherever pipes expand due to fre-quent changes of temperature or pres-sure, wherever vibrations occur in pipework, wherever heavy loads have to be carried, wherever pressure-tight transport of media is essential, wher-ever a high vacuum must be main-tained – these are all situations where flexible metal elements are called for.
Those elements include the actual expansion joints and metal bellows. But also metal hoses, special pipes and the appropriate hangers and sup-ports.
Witzenmann is your first port of call in all these instances. Witzenmann, the inventor of the metal hose and the founder of the metal hoses and expan-
sion joints industry. It all goes back to the year 1885 and the first patented metal hose. The metal expansion joint patent followed in 1920.

Before a new flexible element is released for large-scale production, it undergoes the most rigorous testing in our modern development centre. Equipped with the very latest in elec-trodynamic vibration test rigs. Hot gas and service life testing systems. Corro-sion resistance apparatus. Portable testing units.These tests enable Witzenmann to guarantee the optimum configuration for an expansion joint. And also that the expansion joint can withstand all conceivable loads over a long period. Our large-scale production is also car-ried out with the same degree of care and attention. Our in-house machine design and toolmaking departments work closely with the production department to guarantee stable pro-duction processes and products with the best possible quality. Witzenmann
has been working to these high stand-ards faithfully for a long time. Back in 1994 Witzenmann was the first compa-ny in this sector to gain accreditation to DIN ISO 9001. Such accreditation forms the basis for our leading posi-tion in the marketplace.

Tight Organization of Quality ResponsibilityOur quality assurance is organized on two levels. The central quality assur-ance department is in charge of supe-rior organizational and technological qua lity assurance measures. The qual-ity departments of our product divi-sions deal with quality planning, quali-ty management and documentation within the scope of the execution of orders.In respect to its organization, the qual-ity assurance department is independ-ent of the production department. It has the competence of giving orders to all employees in charge of tasks which have an influence on quality.
Calculation, ConstructionThe Product Development and Produc-tion Processes provides basic informa-tion for the construction and calcula-tion of our products. Comprehensive theoretical investiga tions and tests are the basis of our activities. The individ-ual divisions will finally apply the con-
struction requirements in practice, tak-ing specific product features and cus-tomers' requirements into particular consideration.
Meticulous Supplier AuditsWe only cooperate with qualified sup-pliers who can give proof of an effi-cient quality assurance. For semi-fin-ished products belts, metal plates, pipes, wires, we demand inspection certificates according to the applica-tion of the parts. We make sure that
Fig. 2.1 FEM Structure of a Corrugated Part
the supplied products meet our order and acceptance provisions by means of inspections in our receiving depart-ment and our material laboratory.
Complete Production SupervisionThe supervision department of our company is responsible for inspection and maintenance of production equip-ment and correct execution of produc-tion procedures in the production process according to provisions of the production documents provided.
Proper Execution of Welding ProcessesWelding processes are carried out according to written instructions. The qualification of the welders is guaran-teed by means of examinations according to EN 287-1 (EN ISO 9601-1)/EN ISO 9606-4. The most important and frequently applied welding tech-niques are certified by means of proc-ess inspections. The welding supervi-sion meets the respective require-ments according to AD Sheet HP3.
Supervision of Measuring and Inspec-tion EquipmentAll testing and inspection equipment has been documented They are inspected for precision and reliability at regular intervals. The date of cali-bration can be taken from control marks.
Supervision of the Quality Assurance SystemThe quality assurance measures set forth in the QA System are inspected for compliance by all departments dealing with such measures and checked for effictive ness by means of internal audits carried out at regular intervals.
Quality put to the Test
Product AuditComprehensive systematic audits car-ried out in the last few years have ena-bled us to take the step from empiric knowledge based on routine to the development of systematic knowledge.
2 | QU A L I T Y M A N AG E M E NT 2 | QU A L I T Y M A N AG E M E NT
On one hand, this systematic know-ledge is the precondition for product development and optimizing. On the other hand, it is necessary to meet the increasing demand of the market for information about all product proper-ties, especially, e.g., in case of applica-tions for the purpose of safety in air and space travel and in automotive industry.
Material AuditThe demand for economic production requires the selection of appropriate mate rials. A thorough knowledge of material properties is the precondition for both this selection processes and the demand for an increase in quality and safety.Semi-finished parts for our products are mostly thin high grade strips, wires, metal plates or thin-ply pipes. The high qualitiy demands made on our semi-finished parts are document-ed in our order and purchasing condi-tions. Besides the provisions of national and international standards and regulations, the quality require-
ments also include specific internal requirements concerning production and documentation. In continuous incoming inspections, the parts ar inspected for compliance with geo-metrical, mechanical, technological and chemical properties required in our order provisions.Another task of the material inspection department is the execution of mechanical, technological and metal-lographical audits in the course of process and acceptance audits of welding operations.
Audits of Welding Staff and Welding ProceduresThe welding procedures applied in the production are documented in proce-dure audits. Continuous actualization of procedure audits is one of the tasks of the welding supervision. Further-more, this department is responsible for regular qualification audits of the welding staff (welding staff audits according to DIN EN 287-1 [EN ISO 9606-1], DIN EN 287-1 and EN ISO 9606-4). 11

For non-destructive testing of construc-tion parts and welding seams, we use X-ray and ultrasonic testing devices.
Our material laboratory has been certi-fied by the inspection and clasification institutions that are competent in these fields to be an inspection depart-ment for destructive and non-destruc-tive material testing independent of the production departments. It is therefore authorized to issue inspec-tion certificates.
Damage AnalysisAnother task of the material inspection department is the damage analysis of products after failure during testing or service. As a rule, metallographical inspections are carried out and the type of damage is documented by means of photo graphes.For inspections that go further into detail, the laboratory is equipped with testing devices for material analysis methods as well as for electronic raster scanning microscopy.

Expansion joint qualityIn the interest of our customers, we make stringent demands on our ex pansion joints with regard to per-formance, quality and reliability.
The quality-assurance process there-fore also monitors the incoming ma terials used for manufacturing, continuously supervises production and subjects the finished products to meaningful final inspections before they leave our plant.

In conjunction with this, samples are taken from production and subjected to functional and destructive tests to verify the quality of their design and manufacture.
The use of high-quality materials, optimized manufacturing procedures which are gentle on metarials, modern automatic facilities and equipment and – last but not least – responsible, qualified personnel are however the most important guarantees of quality for our products.

Within the bounds of quality assur-ance, we have defined the minimum requirements on materials in ordering and acceptance instructions for the most popular types.
Certificates can on request be supplied for the materials used against reim-bursement of the costs; if the material is strip material that is normally kept in stock, it can be confirmed with cer-tificate 3.1 to DIN EN 10204, but also according to 3.2.
Possible certificates of performed tests are stated in DIN EN 10204 (see table).
We would like to point out that the scope of the required material tests can have a significant impact on product and testing costs as well as delivery times; disproportionately stringent requirements should there-fore be avoided.

The bellows and its principle of operationThe basic flexible element of the ex pansion joint is the metal bellows, which is flexible on all planes on ac count of its toroidal corrugations; this flexibility is utilized in the expan-sion joint in different ways according to the construction type (Fig. 3.6). The flexibility of the bellows is derived from the flexibility of the radial corru-gation flanks (Fig. 3.7)
axial angular lateral
Fig. 3.6 Types of bellows movement
Fig. 3.7 Principle of operation of a bellows corrugation
The various types of expansion joint serve to compensate movements I pipes, machines and apparatus. The movement, which is always a relative movement between two sections of a plant, is caused by thermal expansion, forming by pressure, inertial forces, misalignment or foundation settle-ment. (Figs. 3.1 – 3.2).
ConnectionsThe expansion joints are connected either by welding them to the pipes or container walls or by flanging them on, e.g. to machine sockets. The standard types of connection part are weld ends and flanges; in special cas-es screwed nipples are used. (Figs. 3.3 – 3.5).

In addition to flexibility, the metal bel-lows must have a certain pressure reli-ability. Flexibility and pressure reliabil-ity are contrary requirements, which in extreme cases result in different corru-gation shapes. The lyre-shaped corru-gation is a good compromise, which combines considerable flexibility and an adequate pressure reliability (Figs. 3.8 – 3.10).
The lyre-shaped corrugation, to which the description below is restricted, can be adapted to specific requirements to a greater or lesser extend by altering its geometry. It is also possible to in crease the number of plies; this is the basis of the best technical solu-tion, namely the multi-ply bellows (see also Chapter 10, “The multi-ply princi-ple“). Figs. 3.11 – 3.13. are diagrams of the various possible types of bellows.
Although the multi-ply bellows is rela-tively complicated with regard to its design and manufacturing process, it is used as the basic elastic element in our expansion joints on account of its

good characteristics, and has proven to be successful over many years, es pecially in constructions which are subject to pressure loads.
AnchoringThe various types of hinged expansion joint are fitted with different types of anchors according to their specific functions; the tasks of these anchors are to absorb the axial reaction force and to permit angular or lateral flexi-bility. The most important types of an chors are shown in Figs. 3.14 – 3.17.The details of the anchoring designs may differ; they are shown in the dia-grams for the individual type series.

Assembly partsThese are a numer of additional as sembly parts which may be required; the most frequently encoun-tered of these are described below.
• Inner sleeve Internal pipe, usually made of stain-
less steel, which protects the bellows from direct contact with the flowing medium and reduces the flow resist-ance.
• Guide sleeve Pipe either inside or outside the bel-
low, which guides it at defined points or over the entire length to prevent buckling.
• Protective sleeve Pipe on the outside of the expansion
joint, which protects the bellows from mechanical damage and from dirt in the lower bends of the corru-gation, and which acts as a carrier for thermal insulation.
• Reinforcing rings Rings in the lower bends of the bel-
low corrugations, to reinforce the bellows against internal pressure.
Technical characteristicsHYDRA expansion joints are in line with the latest state of the art (technol-ogy and manufacturing processes), and are fully-developed, flexible metal elements which are suitable for uni-versal use in modern pipe construc-tion and plant engineering/construc-tion.
Their outstanding characteristics are based on an ideal combination of design details resulting from intensive development work and several dec-ades of practical experience.
The multi-ply bellowsThe multi-ply bellows described above provides HYDRA expansion joints of all types with a series of technical and economic advantages, which are described in detail in the Chapter 10, “The multi-ply principle“; they are list-ed in brief here:
• Suitable for high pressure• Good movement• Compact size
• Low adjusting forces• Optimum compensation in small
spaces• Early indication of leakages
(if damage is likely to occur) through check hole
• Absolute safety against bursting• Permanent leakage monitoring
possible with critical media• Economic use of high-quality,
corrosion-resistant materials, such as Inconel, Incoloy, Hastelloy, titanium and tantalum
• Isolation against impact noise up to 20 dB

The weld connectionThe connection seam between the multi-ply bellows made of austenitic, stainless steel with a ferritic weld end (or flange) necessitates special weld-ing measures; still more stringent demands are made on the design of the welded area and on the welding process when special alloys must be welded. Even though a mechanical load is only placed on the seam by a part of the axial reaction force, namely that acting in the toroidal chamber of the corrugations, and by the slight ad justing forces of the bellows in rela-tion to tension and shear ( < 50 N/mm2), it must nevertheless remain absolutely tight throughout the entire operating period and is consequently crucial to the quality of the expansion joint.
Special measures must therefore be taken to ensure a low stress level. The bending moment produced by the movement of the bellows in the corru-gation flanks is reduced before it reaches the weld connection:
• The raised bellows rim generates a countertorque which relieves the load
• Press-fitted rings reinforce the rim and reduce the stress level
• The cylindrical rim reduces any residual bending stresses
The rim weld seam which is some-times used for expansion joints with smaller bellows dimensions is located roughly at the mid-diameter, where the bending moment of the corruga-tion flank tends to zero, and is conse-quently practically free from moment.It has been proved that the standard seam shown in Fig. 3.19 can be exam-ined non-destructively, due to the low stress level however, the costly exami-nations necessary to assure the quali-ty of other types of seam can be despensed with, and it is sufficient to perform the standard leakage test.
Fig. 3.19 Conection seam of bellows/weld end
The lap-joint flangeLike fixed flanges, lap-joint flanges offer the familiar advantages of flange connections, such as rapid assembly, interchangeability of valves, etc.
Since lap-joint flanges are moreover not welded to the bellows, but form- fitted and assembled on it so that they are rotatable (Fig. 3.20), they have a number of additional advantages:
• The fact that they can be rotated simplifies assembly allowing posi-tive alignment of the flange holes.
• The flanges are not in contact with the media, which may be aggressive, and can be made either of normal steel or of special materials, such as aluminium and plastic.
• The flanges can be protected against corrosion at relatively little costs by means of suitable coating or by galvanization.
• Special materials, which cannot be welded neither to other bellows ply members or to the flange can be used.
Expansion joints with small nominal diameters are fitted for production-related reasons with floating flages with flange rings offering largely the same advantages.The spacer corrugation shown in Fig. 3.20 is a simple means of keeping space clear for bolting, and prevents the corrugations at either end to move freely.

Patented anchoringHammer-shaped anchors inserted in plates (Fig. 3.22) combined with multi-ply bellows permit extremely short total lengths to be used for the HYDRA hinged expansion joints. The full ben-efit of this advantage is particularly apparent in hinge systems with an gular expansion joints, since it also results in small overall dimensions for the hinge system and any other con-struction which are necessary.
The hammer-shaped anchors are form-fitted to the plates and the plates are welded around the pipe so that the forces/stresses are evenly distributed. The effects of unintentional overload-ing of the anchoring, e.g. as a result of impulse pressure, are consequently less drastic; the plate yields and is formed without generating excessive stresses in the pipe. Together with the effective safety against bursting of the multi-ply bellows, this acts an efficient safety reserve.
Fig. 3.22 Hammer-shaped tie rod
The inner sleeveInner sleeves are used whenever expansion joints must be protected from:
• Abrasion caused by solid particles in the flowing medium
• Deposits of solid components in the corrugations
• Vibrations generated by high flow velocities
Inner sleeves theoretically also reduce the pressure losses in the flow through the expansion joint; in practice how-ever these pressure losses are so slight – roughly twice as those in a pipe of identical length – that the ex penditure is rarely worthwhile.
Our expansion joints with lap-joint flanges are provided with press-fitted, form-fitted inner sleeves (Fig. 3.21), they can also withstand vibration loads.

exhaust systems, in district heating and compressor pipe systems and in cryoengineering. 1.4571 has proven itself, above all, for decoupling ele-ments in exhaust systems of motor vehicles and when used in drinking water piping. As with 1.4541, 1.4571 is stabilised with titanium, which increases its resistance to intercrystal-line corrosion. In addition, molybde-num is added in 1.4571, so that it is more resistant to pitting corrosion than 1.4541, which can occur in the presence of chlorides.
Material 1.4301For strip-wound hoses, which are used in, for example, exhaust systems of trucks, the high-alloy steel 1.4301 exhibits adequate corrosion resist-ance. The corrosion resistance is attributable to the elements chromium and nickel.
Material 1.44041.4404 is used for components in vac-uum equipment; it has also proven itself as hose material. In principle, it can be used in the same ways as 1.4571. The chemical composition largely matches that of 1.4571. In com-parison to 1.4571, 1.4404 is not stabi-lised with titanium. Through a reduced carbon content of less than 0.03%, however, it exhibits a similar resist-ance to intercrystalline corrosion. Owing to the reduced carbon content, the strength characteristics are some-what lower than those of 1.4571.
Materials for high temperaturesFor higher temperatures (>550 °C), where high scaling resistance is required, high-temperature or heat-resisting steels are taken into consid-eration if they have adequate forming properties (e.g. 1.4828, 1.4876 or 2.4856).
General instructions of choice of materialsThe wide variety of applications for which our bellows are used necessi-tates an appropriate choice of materi-als.
In the appendix A material tables we have listed the common materials we use and the more frequently used spe-cial materials with all necessary data in order to simplify selection of suita-ble materials in each case. The most important requirements on the material are in general:• Corrosion resistance• Temperature resistance• Strength• Welding properties• Forming properties
Bellows materials
Materials for general applicationsStandard materials from the group of stainless, austenitic steels are 1.4301, 1.4541, 1.4571 and 1.4404. These materials are especially able to satisfy the requirements over a wide range of applications. In respect of quick availa-bility and optimised stock holding, for general applications Witzenmann manufactures bellows from 1.4541.
Material 1.4541 – standard for bellows manufacture1.4541 is used in the chemical indus-try, food industry, in exhaust systems, in district heating and compressor pipe systems and in cryoengineering. Since titanium is used for alloying in 1.4541, unlike 1.4301, this material has better resistance to intercrystalline corrosion up to 400°C.
Material 1.4571As with 1.4541, 1.4571 is used in the chemical industry, food industry, in

Material 2.4856 (Inconel 625)Expansion joint bellows that are exposed to seawater are preferably made of Inconel 625. The molybde-num-containing material 2.4856 has excellent resistance to pitting, crevice and stress crack corrosion.
Material 2.4610 (Hastelloy C4 / - C276)Bellows of these two materials are used in chemical and other process engineering plants. They are excep-tionally resistant to hot acids, chloride-containing solutions or even chlorine gas up to temperatures of 400°C.
Expansion joints for corrosive operating fluids Suitability of metal expansion jointsExpansion joints with corrugated met-al bellows are basically suitable for the transport of critical fluids under pres-sure and temperature.
The flexibility of the corrugated bel-lows of expansion joints generally
requires their wall thickness to be considerably smaller than all other parts of the system in which they are installed. As increasing the bellows wall thickness to prevent damages caused by corrosion is not reasonable, it becomes essential to select a suita-ble material for the bellows element, which is sufficiently resistant against all aggressive media that may occur during the entire lifetime. In many cas-es the bellows has to be manu- factured of a material with even higher corrosion resistance than those of the system parts it is connected to.
In addition, possible corrosive envi-ronmental effects must be considered.
The material selection must take into account all possible kinds of corrosion, especially pitting corrosion, intercrystalline corrosion, creve corrosion cracking (SCC).

Material 1.4828The material 1.4828 has proven itself as strip-wound hose liner in decou-pling elements, as expansion ele-ments in manifolds of engines. Owing to its high silicon content, 1.4828 has good scaling resistance.
Material 1.4876 (Incoloy 800 H)The material 1.4876 is used where compressive stresses occur in addition to high temperatures, e.g. in the inlet and outlet pipes of engine turboch argers. 1.4876, in which aluminium is added, has even better scaling resistance than 1.4828; the chromium and nickel content is also significantly higher, but this makes it more expen-sive and reduces its suitability for forming. 1.4876 exhibits excellent long-time rupture strength characteris-tics and is approved for components under compressive stresses at temper-atures above 550°C.
Material 2.4856 (Inconel 625)Use of the nickel-based alloy 2.4856 is recommended where high tempera-tures occur as well as corrosive stress, e.g. with chlorides.
Materials for corrosive mediaEspecially corrosive conditions require the use of special materials that should at least have the corrosion resistance of the connected pipe or fittings. If in doubt, a higher-grade material should be chosen. In many cases, nickel-based alloys are suitable for this, a fact that is substantiated by good experiences. In special cases, titanium or tantalum is the only alternative.For expansion joint bellows, the materials 2.4856 (Inconel 625), 2.4610 (Hastelloy C-4) are preferred, and for bellows of smaller size (diameter < 100 mm), the material 2.4819 (Hastelloy C-276).

Selection of a suitable materialThe material for the bellows layers is to be selected according to the specific aggressiveness of the operating fluid or for the surrounding atmosphere. References for material resistance can be found under appendix B – Resist-ance tables.
Responsibility of the manufacture for the suitability of expansion jointsThe expansion joints manufacturer is responsible for the design of the expansion joint according to the given pressure, temperatures and move-ments, and for the material concern-ing its formability and weldability.Witzenmann contributes his wide scope of experience when assisting the user in selecting a suitable materi-al.
With regard to the influences of the operating situation given in the plant only the operator can take full respon-
sibility. The advice of the expansion joint manufacturer can only be given without obligation, i. e. without any liability for the material to be selected for the special application.
Fittings, flange materials and materi-als for anchorsWhen choosing materials for connec-tion fittings, strength and welding properties are particularly important.For flanges and fittings, unalloyed steel and general constructional steel is normally used. Where there are higher operating temperatures, high-temperature steels are used. Under higher stresses or lower temperatures, fine-grained constructional steels and low-temperature steels are used.
Under corrosion-critical conditions, fittings of compound steel, stainless, ferritic or austenitic steels and nickel-based alloys are used.

Safety and economy with expansion
joints
Expansion joints are required in al most all technically oriented branches of in dustry where plants must be operated reliably. They must perform a variety of tasks, such as:• Compensationofthermalexpansion in pipes• Decouplingofequipmentvibrations from connected systems (e.g.compressorsetc.)• Compensationofrelativemove- ments between plant sections• Isolationofstructure-bornenoise• Reductionofforcesandmomentsat connections.
Itisnotmerelyessentialtoemploy flex ible, metal expansion joints in modernplantandapparatusengineeringandconstructionfortechnicalreasons; it is equally important to meet
the re quire ment of all branches of industry for:• Improvedeconomicefficiency• Reducedplantsize• Easeofassembly• Trouble-freeoperation• Safetyintheeventofsystemmal function.

Compensation types and selected criteriaThere are three basic types of compensation, namely:• Compensationbyelasticbendingof
pipelegs(“naturalcompensation”)• Axialexpansionjoints• Anchoredexpansionjoints(hinged
expansionjoints)
The relevant characteristics are as follows:• Magnitudeandtypeofmovement
which must be compensated• Pipelinerouting• Forcesandmomentsactingon
anchors and connections• Installationspacerequiredfor
expansion joints• Overallcostofcompensation• Assemblywork
The above overview of characteristics permits a qualitative comparison of the compensation types – either compensation with axial expansion joints or compensationwithhingedexpansionjoints–andisanimportantdecision-makingaid.
Compensation by pipe bendingThe question as to whether compensation, for example of thermal expansion, is possible by means of the intrinsic elasticityofthepipesystemisgenerallysuperfluous due to the fact that with largediameterspipelegswhicharesufficientlylongarenotavailable(Fig.4.1).Extendingthepipesartificiallyorlayingthemwithbendsishoweverusually not feasible for economic reasons, as has been demonstrated by numerousexaminations.(High-pressure steam pipes in power stations are one example of an exception made for technicalreasons).

Anchor forceWhen axial joints are used, the anchor force is made up of the axial reaction force FP,theaxialadjustingforceF and the friction coefficients of the supports FR; these are calculated as follows:

Therefore, even our standard expan-sion joints fulfil the additional require-ments of the Pressure Equipment Directive.
Our expansion joints can be employed in a vast range of applications. There-fore, we have designed them for use in all categories up to category IV.
Witzenmann has implemented, oper-ates and maintains a quality assurance system as described in the pressure equipment directive (97/23/EC) Annex III, Module H/H1 for the scope of design, manufacturing and distribu-tion of expansion joints and metal bel-lows. This also applies to all other conditions. Certification of the raw materials, methods and manufacture and personnel. That means customers can rely on design and selection of
expansion joints in compliance with the Pressure Equipment Directive. Work in accordance with the Pressure Equipment Directive takes place in defined modules. These depend on the category selected. Therefore, the extent of testing and documentation is defined accordingly.
Witzenmann – a Member of EJMAWitzenmann is a member of the Expansion Joints Manufactures Association (EJMA). Every expansion joint pruduced by Witzenmann can be designed and manufactured in strict accordance with EJMA standards.
Detailed calculations to validate design in accordance with latest edition of the EJMA standards are available to every Witzenmann customer.
IntroductionThe basis for selecting the right expan-sion joint is our comprehensive stand-ard range. Individual series designed and arranged according to nominal diameter, nominal pressure and nomi-nal travel. That makes selection quick and dependable. Guarantees cost-effec-tive, fully designed installations. Achieves short and reliable delivery times.
Wherever an expansion joint has to be designed for a very particular applica-tion, our engineers optimise the joint to meet the customer’s engineering and economic specifications. Even the initial quotation includes exact compu-ter-assisted data.
Design codesThe manufacturer is responsible for providing a properly designed expan-sion joint. “State-of-the-art” design is indispensable, complying with nation-al and international standards. As many pressurised lines fall under the remit of the EU’s Pressure Equipment Directive, the associated expansion joints, too, are classed as pressurised components in the meaning of this directive. CE marking is a must.
The Pressure Equipment DirectiveThe Directive applies to all expansion joints with a maximum permissible pressure PS > 0.5 bar, provided the specific application does not explicitly exclude this.

Pipe SectionsA pipe system must generally be sub-divided into a number of suitable sec-tions to ensure optimum compensa-tion, these sections being separated by means of anchors; the type of compen-sation must be taken into account. Machines and containers must be con-sidered to be anchors if they are not flexibly supported.
Axial compensationOnly straight pipe sections without off-sets are permissible. Long, straight sections must be split up by means of intermediate anchors if several axial expansion joints are required to com-pensate the complete pipe section. Only one expansion joint must be in stalled between each pair of anchors (or intermediate anchors).
Anchors must be installed at the corner points at which pipelines are re routed. A sliding anchor may be installed in stead if the axial expansion joint (or a universal expansion joint) can be sub-jected to a lateral stress (Figs. 5.1 and 5.2)

Determining movement values
The following types of relative move-ment must be absorbed by the expan-sion joint (examples):• Thermalexpansion• Pressurestretch• Vibrations• Compensationofmisalignement• Foundationsettlement• Assemblymovement.
The highest movement values are generally caused by thermal expan-sion; this is discussed separately and in detail below.
Pressure stretchPressure stretch occurs at containers and in pipes as a result of a pressure load; it is however only significant in conjunction with large dimensions, which may have an important effect on compensation. When its magnitude is estimated, it must be remembered that in a long, closed cylinder the lon-gitudinal stresses caused by pressure are half the magnitude of the circum-
ferential stresses. If a full pressure utilisation coefficient is assumed, the values for normal steel are as follows: Rp 0.2 = 210 N/mm2, E = 21 · 104 N/mm2 and S = 1.5 (safety factor for pressure tanks), taking into account the trans-versal contraction:
(5.1) p ≈ 0.1 mm/m
This value is generally negligible, except, for example, in extremely high columns or containers, such as blast furnace, whose axial pressure stretch may result in lateral stresses in expan-sion joints with large diameters in connecting pipes.
There is no pressure stretch in pipes with axial expansion joints due to the lack of a longitudinal force.
Compensation with hinge systemsWhen a complex pipe system is sub-divided into sections, the aim should be to achieve the basic subsystems shown in Figs. 5.3 to 5.5, namely a U-system, an L-system or a Z-system.A straight pipe section is not suitable for compensation by means of hinged expansion joints; the pipeline is there-fore usually rerouted “artificially” by creating a U-system.

Assembly movementIf space must be created for assembling or dismantling valves, a suitable type of expansion joint can be used, namely so-called demounting parts (see Chap-ter 9, “Special designs”, Fig. 8.16). The assembly procedures are generally so infrequent that the expansion joint can withstand large movements (before the corrugations are blocked).
Thermal expansionThe linear thermal expansion of metal components, referred to a temperature difference, can be determined by means of the material-related elogation coeficient.Thermal expansion in mm
(5.2) = L · ·
Component length L in m (e.g.pipe section between two anchors) Mean thermal expansion coefficient in mm/mK (see Fig. 5.7)Temperature difference in K (Difference between operating temp. and assembly temp.)
VibrationsVibrations occur in machines where masses are moved (e.g. in turbo-engines, piston engines and centrifug-es), and are defined in terms of their frequency and amplitude. The fre-quencies are primarily dependent on the speed; in this type of aggregate, it is moreover possible to establish har-monic vibrations with a multiple of the speed but only a low amplitude.The amplitudes of sustained vibrations in well-balanced machines are normal-ly less than 1 mm, and are only higher temporarily during the start up phase and when traversing critical speeds (see also Chapter 13, “Vibrations and noise”). Centrifuges are an exception, in that considerably high vibration amplitudes can occur in them.
Compensation of misalignmentExpansion joints can be used to com-pensate assembly inaccuracies, pro-viding this is taken into account when these are chosen. Since only a one-off movement must be compensated, it can be theoretically be borne by the
ex pansion joint without any impair-ment to its service life; in practise, how ever, the corrugations can very soon become either fully or partially blocked, which means tat normal move ment will be impeded and the expansion joint will fail at a relatively early stage. This risk is especially high if a relatively short axial expansion joint is used to compensate lateral misalignments.
Foundation settlementFoundation or groud settlements are likewise normally one-off movements, and may thus be greater for an expan-sion joint than the values specified for 1000 stress cycles. If a one-off founda-tion settlement is the only movement which is expected, even excessive forming of the corrugations may be ac ceptable, and the expansion joint will remain tight. Settlement which occues when containers are filled and which disappears again when they are drained must be dealt with according to the stress cycles in the same way as other compensation movements.

Assembly temperatureThe assemly temperature can normal-ly be taken to be = 15 to 20 °C, when determining the temperature differ-ence which must be taken into ac count in the movement calculation; at low operating temperatures of around 100 °C, it is necessary to pro-ceed somewhat more precisely and to take a mean temperature at standstill. A check must also be made to deter-mine whether the pipe can still con-tract sufficiently at the lowest possible standstill temperature without the
expansion joints being overstretched or the hinge system being geometri-cally overloaded. Particular attention must be paid to the possile extreme positions of the expansion joint or of the compensation system at the maxi-mum and minimum outside tempera-tures, as well as to correct pretension-ing at the prevailing assembly temper-ature in pipes which are really cold and which only stretch or contract as a result of the prevailing outside tem-perature.

Real movement valuesThe real movement of the individual expansion joints can be determined from the previously established relative movements – usually thermal expansion – in the various pipe sections.
Axial and lateral expansion jointsIf axial or lateral expansion joints are used, the movement values which are determined correspond to the real expansion joint movements.
Hinge systemsThe movement values established in hinge systems must be converted to angular movements. A good approximation can be achieved with the aid of the graph below (Fig. 5.9).
The conversion is exact if the system is a simple double-hinge system with hinges arranged perpendicularly above one another; in other systems the angles are determined approxi-mately, whereby the diffenrence in relation to the exact angles is small
and dependent on the arangement of the hinges and on the magnitude of the movement which must be absorbed.
The relevant movement value must first be determined for the particular hinge system in accordance with Fig. 5.8a, 5.8b. The expansion joint angle must then be read from the graph (Fig. 5.9), together with the hinge distances A and B.
The hinge distances A and B.which are selected should be as large as permitted by the overall construction, and should be such as to ensure small ex pansion joint bending angles and – above all – the smallest possible forces and moments in the pipe sys-tem. The smallest possible dis- tance should be selected for C.
The bending angles which are deter-mined are real angles of the system at operating temperature, and are also valid when the cold system is pretensioned.
If the system is to be operated without pretension, the angles obtained will be roughly twice as large, and correspon-dingly larger expansion joints will be necessary. The real bending angles must be converted into nominal angles in order to select the best expansion joints, where by the poten-tial effects of the operating tempera-ture, the pressure utilisation coefficient and the number of stress cycles must be taken into account.Since this applies generally to all types of movement, the section below refers to all types of expansion joint.

Universal expansion jointsWe have developed a standard range for this type of expansion joint, which comprises of two bellows connected via an intermediate pipe and which can cope with all types of movement – axial, lateral and angular; this range is designed for the more common types of application (type series UBN, URN). The values for the movement speci-fied in the dimension tables (axial, lat-eral) are alternatives, i.e. the percent-age values must not exceed 100% when added together.If any additional requirements must be met, universal expansion joints can be designed on the basis of the axial ex pansion joints in the standard range. Axial expansion joints with only one bellows for absorbing “uni-versal” move ments must also be dis-cussed in this context.The calculation formulae for possible angular or lateral movements, equiva-lent to the nominal axial movement 2N, are specified, together with equa-tions for determining the adjusting-
force rates for these types of move-ment (extremely good approximations).
It is important to remember that the pressures valid for axial expansion joints are hardly ever permitted for universal expansion joints.
The necessary presure relevant reduc-tion factors are shown in the graphs below (Fig. 5.11 and 5.14).

Nominal diameter DNThe nominal diameter of an expansion joint depends on the dimensions of the pipe or the flange connections. Select an expansion joint to suit these criteria.
The standard wall thicknesses of weld ends are given in the tables. These thicknesses meet the requirements of the nominal pressure rating. If possi-ble, standard wall thicknesses of weld-ed pipes to DIN EN 10220 have been chosen.
Flanges with dimensions to DIN EN 1092 part 1 are preferred. The flange thicknesses of lap-joint flanges have in each case been adapted to suit the stresses prevailing in the expansion joint and in some cases are different to those of standard welding neck flanges. Flanges with other dimen-sions are possible, e.g. to the US
standard (ANSI). Also non-standard flanges for special machine connec-tions. Flanges with pitch circle diame-ters smaller than those given in DIN EN 1092 part 1 must be checked to ensure that the screwed fixing is com-patible with the bellows side.
Nominal pressure PNThe standard expansion joints are designed for a nominal pressure (PN) and arranged in PN ratings in the tables. (The nominal pressure parame-ter corresponds to the permissible operating pressure at room tempera-ture, rounded off to a PN nominal pres-sure rating to DIN EN 1333.) It is known that at higher temperatures the permis-sible pressure is lower than the nomi-nal pressure because the characteristic strengths of the materials used are cor-respondingly lower at higher tempera-tures. The permissible nominal pres-sure must be reduced accordingly.

Pressure reduction factor (temperature-related)The reduction factor is defined as: (5.9) Characteristic strength: Rp/t – proof stress in N/mm2 at
design temperatureRp/RT – proof stress in N/mm2
at room temperature
The proof stress Rp is valid for the characteristic strength over a wide temperature range. At higher tempera-tures the creep and stress rupture properties play a role.
Our expansion joints are designed in such a way that the reduction can be based on the material of the bellows.
The choice of a suitable nominal pres-sure is based on the cold pressure PRT, This may not be greater than the nom-inal pressure:
(5.10)
PS – maximum permissible operating pressure in bar
Kp – pressure reduction factor based on operating temperature
The test pressure PT must be at least equal to the larger of the two values given by the equations below:
for a water pressure test
(5.11)
for a gas pressure test
(5.12)
f0 – permissible stress in N/mm2 for design conditions at test temperature
f – permissible stress in N/mm2 for design conditions at design temperature
The expansion joints are designed to withstand a test pressure of 1.43 times their nominal pressure. If a high-er test pressure is required, this must be taken into account when determin-ing the PN rating.

Nominal travel and nominal angleThe nominal travel should be calculat-ed from the true movement values determined beforehand so that it is possible to choose a suitable expan-sion joint from the tables. The nominal travel is based on a service life of at least 1000 full load cycles at room temperature and maximum pressure, and are valid for the standard bellows material 1.4541.
A load cycle here means the total movement of the expansion joint from some starting position to an extreme position on one other side, then returning via the starting point to an extreme position on the other side and then back to the starting position.
The service life is influenced by• pressureutilization • movement • pressurepulsation
plus other factors whose effects can-not be calculated or are unacceptable, such as
• thermalshock • corrosion • damage(improperinstallation,dam-
aged corrugations, etc.)• resonance(e.g.flow-induced).
Up to 500°C the temperature has no influence on the amount of move-ment. Please consult us for higher temperatures.
The correction factors given below are valid for the standard materials 1.4541 (≤ 550°C) and 1.4876 (> 550°C). Other materials with comparable character-istic strengths behave very similarly and can be handled in a similar way. However, materials whose characteris-tic strengths deviate considerably from the values given here cannot be dealt with in this way, or not accurate-ly enough. That frequently calls for a different approach. Please consult us if you wish to use special materials.
Low temperaturesThe standard versions can be used in temperatures down to = –10 °C without having to apply a reduction factor.
At lower temperatures low-tempera-ture steels should be chosen for the
ferritic parts. The table below specifies suitable materials approved to the AD 2000 standard that enable the expan-sion joint to be loaded to maximum. At very low temperatures down to = – 270 °C it is possible to use a ver-sion made completely from the auste-nitic material 1.4541.

Cumulative movementIf an expansion joint is to accommo-date movements with different num-bers of load cycles, the respective cold values (related to 1000 load cycles) are determined first. Afterwards, the theo-retical total travel of the cumulative movement can be calculated reasona-bly accurately using the following equation:
(5.17)
The cold travel and nominal pressure calculated as described above can now be used to select the necessary expan-sion joints from the standard range.
Pressure pulsationThe pressure pulsations or dynamic operating pressures superimposed on the static pressure have an influence on the service life. Their effect, which can be calculated and allowed for, depends on the magnitude of the pressure fluctuations in relation to the nominal pressure, and their frequency. Generally, pressure fluctuations are negligible. However, if the magnitude and frequency of pressure surges are expected to have a detrimental effect on the service life, please consult us.
When designing expansion joints it is usual to check the utilisation condition (related to load cycles): D = ∑ (Ni,reqd/Ni,calc) ≤ 1.

Inner sleeveAn inner sleeve is used to protect the bellows when deposits or abrasion are anticipated. Also if high flow velocities could excite the corrugations of the bellows and cause them to vibrate.
The diagram on the right shows maxi-mum values for flow velocities per-missible without an inner sleeve. These figures are based on an unfa-vourable flow towards the corruga-tions.
The inner sleeve can also act as an internal guide sleeve (in special ver-sions) and is indispensable in such cases. In addition, it can also act as a mounting for an internal brick lining, but in this case calls for a special design. If an inner sleeve is necessary but must not hinder lateral or angular movement, tapering or stepped sleeves can be incorporated.
MaterialsWe have selected material combina-tions for standard expansion joints that are adequate for the majority of applications. The most important aspects when choosing the material of the bellows are generally:• formability• weldability• thermalstability• strength• corrosionresistance
Our standard material, 1.4541, a non-corroding austenitic steel, satisfies these requirements admirably for a wide range of requirements.
Provided they possess adequate deformability, high-temperature or heat-resistant steels (e.g. 1.4876, 1.4828) can be used for higher temper-atures ( > 550°C )
In particularly aggressive conditions special materials with a corrosion resi-
stance at least equivalent to that of the adjoining pipe must be used. This is because the relatively thin walls of the bellows and their function – to remain highly flexible expansion-contraction elements – does not permit any corro-sion allowance. If in doubt it is best to choose a higher-quality material for the bellows, at least for the inner ply. In many cases nickel-based alloys, with which we have had good experi-ence, are suitable.
The choice of a suitable corrosion-resistant material should be based on the experience of the user, who is familiar with the particular features of his system and his operating medium. The resistance tables can prove help-ful when making a choice. Please note that special materials with – in com-parison to 1.4541 – completely differ-ent physical parameters (e.g. alumini-um) will inevitably lead to different dimensions and performance data for the bellows.

Larger expansion joints up to 12 m in diameter, and designed for higher pressures, can be supplied on request.
The standard expansion joints are of different construction types, such as axial, angular and lateral expansion joints, and are listed separately accord-ing to type series; in addition to the construction type, the type series also specifies such features as the connec-tion type and any particularities of the design.
The individual type series are classified according to the nominal pressure rat-ing, the nominal diameter and the movement value.
The design of the standard expansion joints, of which variant can be supplied on request is defined initially in rela-tion to the connections and materials:
Connections:Weld ends according to ISOFlanges according to DIN 2501
Materials: According to the table below, temperature-related.
GeneralThis manual deals with the expansions joints used for pipeline construction and for plant and apparatus engineer-ing. The expansion joints are designed for 1000 stress cycles in line with the standard mode of operation of thermal plants, which corresponds to 20 years operation if the plant is started up and shut down once a week. Other designs are also possible.

Special Ranges
The standard ranges described in Chapter 6 are supplemented in this chapter by a series of special ranges of expansion joints and related prod-ucts.
These products are primarily designed either for special applications – engine manufacturing, apparatus engineering, district heating – or for special per-formance data, e.g. high pressures.
Type series are available for the more frequently demanded dimension rang-es; special designs outside these rang-es can be supplied on request.
The table overleaf provides an over-view of the special ranges.

The requirement for simple assembly is met by means of the special installa-tion rims (see. figs. 7.2 and 7.3).
The movix connection is a snap-on fixing developed by witzenmann; it uses a wire-pressed formed ring made of heat-resistant material to seal and secure. This ring is press-fitted togeth-er with the conical rim of the bellows by means of a v-band clamp; an unmachined pipe is a suitable mating part (fig. 7.4).

Fig. 7.2 Conical rim for V-band clamp Type series AOK
Exhaust expansion joints with special rims
exhaust expansion joints which must be mounted directly at the engine are subjected to abnormal conditions:
• Hightemperatures( ≥ 400 °C)• Temperaturepeaks,accordingto
engine output• Absorptionofthermalexpansion
and sustained vibrations• Compactdimensions,sinceavailable
space usually restricted• Assemblyanddismantlingmustbe
rapid if the engine needs to be over-hauled or repaired.
we supply special designs based on existing tool series (see table) to meet these requirements; they are tailored to specific applications and have in some cases been developed jointly with the engine manufacturers. Special tools can also be manufactured if nec-essary. when developing new designs,weareabletomakeuseofour wide-ranging experience and our specially adapted testing facilities, which is an advantage with regard to both development times and costs.

C = Cw / nw
The nominal movement, the total length and the adjusting-force rate of the mul-ti-corrugation expansion joint are de pendent on the selected number of corrugations (rounded up to integer number):
Nominal movement 2N in mm
(7.2)
(Rounded down to integer mm)
Total length lO in mm
(7.3)
length of single corrugation iw in mmlength of rim lB in mm
Adjusting-force rate C in N/mm
(7.4)
Adjusting-force rate of single corruga-tion Cw in N/mm
The rim diameter dB can be adapted to the available connections. The dimen-sion tables specify the permissible diameter range; the desired dimension must be indicated in the order.
It should be noted that the cylindrical section of the rim lBZ must be at least 10mm long.The transition zone must be between 4mm and lw/2 long on account of the production technology used.
Prequalification, insoection tests, cer-tificates and documentation must be agreed upon when the order is placed, for use in systems requiring inspection.
Single-ply expansion joints for appa-ratus engineeringThe special range of single-ply ex pansion joints designed for appara-tus engineering and container con-struction is highly effective in meeting the special demands of these fields:
• Thick,single-plyforweldingdirecttothe container wall
• Goodlateralrigidity,whichrendersaxial guides in the container super-fluous
• Smallcorrugationswithoutcircum-ferential seam welds for optimum overall dimensions
The design conforms to the Pressure-TankOrdinanceandhasbeencalculat-ed according to AD Code of Practice B13.

Axial expansion joints for heating and ventilating installationsWehavedevelopedaseriesofaxialexpansion joints especially for the needs of heating and sanitary engineering; the different types of connection are adapted to specific assembly condi-tions:• Weldends• Rotaryorfixedflanges,drilledaccor-
dig to Din• Screwednippleswithpipethread,
male or female.
The connection parts are made of c- steel as standard, whilst the corrugated metal bellows are made of stainless steel1.4541;theyprovideexcellent corrosion resistance for reliable opera-tionextendingoverseveraldecades.The expansion joints are designed accordingly for 10000 full stress cycles (in contrast with the standard range), asnecessaryinheatingandventilatinginstallations on account of the more frequent temperature changes.Guidesleevesareprovidedinsomedesigns; they simplify flush installa-
tion, though they cannot replace slide points or anchors.Designswithanexternalprotectivesleevearepretensionedinthefactory;assembly errors are thereby precluded to a large extent and the thermal insu-lation is simpler to install.
Nominal diameters: DN 15-100Nominal pressures: PN 6-25

High pressure metal bellows and expansion jointsOur standard ranges include expansion joints with nominal pressure ratings which are fully adequate under normal circumstances for pipeline construc-tion/plantengineeringandconstruc-tion.
if a higher nominal pressure is neces-saryinindividualcases,forexampleinheatexchangers,individuallydesigned expansion joints can also be supplied. if the combined require-mentsofpressureandmovementcause the technical limits to be reached when pressure is applied to the expansion joints internally, it is sometimes possible to use reinforcing rings or to apply pressure to the bel-lowsexternally(seealsoChapter8,“special designs”).
in addition, metal bellows, such as thoseusedassternsealsinvalves,must often be designed for high pres-sures, which are generally applied externally.

Axial expansion jointsHYDRAFLON axial expansion joints for chemical tankers(Fig.8.7)The special expansion joint for prod-uct- and chemical tankers combines the good flexibility and pressure relia-bility of multi-ply expansion joints with the excellent resistance to chemi-calsandseawaterprovidedbytheinternal pTFe liner. its other main characteristic – it can be flushed, even if the pipeline is routed horizontally.
The special HYDraFlOn axial expan-sion joint has a multi-ply, stainless-steel bellows with a special corruga-tion shape, to which support elements for the internal liner can be fitted. The internal liner is made of polytetrafluor-oethylene (pTFe) and is resistant to the chemicals which must be transpor-ted. its shallow corrugations and its smoothsurfacepreventtheconveyedproducts from sticking and permit the pipe to be cleaned by flushing; there arenoresiduechemicals,eveniftheexpansion joint is installed horizontally. The liner is bent around the flanges
with a special, corrosion-proof coat-ing, and also acts as a seal. The outer – likewise corrosion-proof – ply of the bellowsismadeofIncoloy825,anick-el-based alloy, which is resistant to seawater and which allows the expan-sion joint to be used on the deck.

Axial expansion joints, pressure applied externally(Fig.8.8)The bellows of this design is arranged so that an external pressure is applied to it. This makes the design more complex, since bellows with a larger diameter and an additional, pressure proof outer casing are necessary, but on the other hand offers a number of potential,crucialadvantages:
• Extremelylargemovementincon-junction with low adjusting forces, since the stability problems which wouldhavetobetakenintoaccountif the pressure was applied internally are practically insignificant
• Thebellowsareprotectedfromdamage by the outer casing
• Noresiduesofaggressiveliquidsorcondensates remain in the curroga-tions, since they can flow off
• no deposits of solids can remain in the currogations, since the currogations are not located in the line of flow
• Theexpansionjointandthedown-stream pipe can be completely drainedandvented.(Note:Itisnor-mally necessary to drain the bellows corrugations of HYDra expansion joints with small corrugations, since onlyasmallvolumeofliquidcanremain in the corrugations.)

Axial expansion joint with leakage monitoring(Fig.8.10)
Ifcriticalmedia(toxic,explosive,flam-mable)areconveyed,itmaybeagoodideatoprovidepermanentleakagemonitoringatthemovablepipeele-ments, to enable any leak to be de tected at an early stage.The multi-ply bellows with spirally wound intermediate plies has a uniqueadvantage–thepatentedleak-age-indication facility.
check holes in the intermediate plies, made at defined points in the rim re gion of the bellows, are guided into an toroidal chamber, which is also monitored for leaks. This enables any onset of damage anywhere in the inner ply to be detected in good time (see chapter 10, “The multi-ply principle”).
Other types of leakage monitoring are possible at low operating pressures using a double-ply bellows and special connectionparts(Fig.8.11)oracham-berexpansionjoint(Fig.8.12).

Chamber expansion joint(Fig.8.13)
Heated pipes or double pipes for con-veyinghighlyviscousmediaormediawhich solidify at room temperature require chamber expansion joints to compensate thermal expansion and to ensure “force free” connections.
The chamber expansion joint with flange connection shown below is a frequently used type; the actual medi-um flows inside it, whilst the toroidal chamber is used for heating.
The connection for the heating fluid, e.g.steam,isprovidedviatheflanges,frequentlyusingmetalhoses(Fig.8.13).Weld ends can be used as connection partsasanalternativetotheflanges.
chamber expansion joints can also be used for pipes which must be cooled.
chamber expansion joints whose toroidal chamber is fitted with a leakage indication facility can be used specifi-cally for leak tightness testing, for
example in conjunction with toxic media(Fig.8.12).
Expansion joint with a toroidal bellows (Fig8.14)This type of bellows is suitable for ex tremely high pressures in conjunc-tionwithrelativelymodestmove-ments; this corresponds to the requirements of apparatus engineer-ing. The circumferential stresses in the bellows are reduced by the thick walls of the connection parts.Ifseveraltoroidalcorrugationsarenecessaryduetothestipulatedmove-ment, reinforcing rings must be fitted betweenthem(Fig.8.15).

Expansion joint with reinforcing rings (Fig.8.15)reinforcing rings are used if the circum-ferentialstressesbecomeexcessiveasa result of high operating pressures, generally combined with large diame-ters, and it is no longer either techni-callypossibleoreconomicallyadvisa-ble to increase the number of plies or the thickness of the bellows wall. The reinforcing rings absorb the circumfer-ential stresses instead, so that the wall ofthebellowscanremainrelativelythinandflexileoverall.

Expansion joints with pretensioners (Figs.8.17/8.18)axial expansion joints can be fitted with pretensioners to simplify assem-bly on the building site.

The adjustable pretensioner, which comprises threaded rods and nuts which link the connection parts of the expansion joints together, enables the installation length to be set simply and rapidlyforassembly(Fig.8.18).

pretensioners are usually only designed to absorb the adjusting forc-es; they cannot absorb either addition-al loads or the axial reaction forces.

Elbow-connected pressure balanced expansion joints(Fig.8.29)The design and implementation of an elbow-connected pressure balanced expansion joint is dependent on spe-cific requirements, and takes the oper-ating conditions and the necessary movementvaluesintoaccount(seealso chapter 15, “axial reaction force and pressure balanced designs”). The diagram below shows an axially and laterally flexible, elbow-connected pres-sure balanced lateral expansion joint.
Angular expansion joint with PTFE bearings(Fig.8.30)if the adjusting moments of our angu-lar expansion joints, which are already small, are too high for your particular application, it is possible to reduce the frictional moment in the hinge points still further by using a special bearing. The pTFe compound bearing we use for this purpose has a special design which permits it to withstand high con-tact pressures without the plastic anti-friction coating being pushed aside. The good sliding characteristics of the
bearing are thus maintained through-out the entire operating period. The bearing can withstand temperatures upto280°Candisabsolutelymainte-nance-free.

Positioning in pipe
systems
Installing expansion joints in a pipe can cause substantial changes in its behaviour; anchors and guides are sub jected to different stresses, and the functions they must perform are not the same as in an umcompensated pipe system.
The general rule which must be ob served when assembling expansion joints are summarized in Chapter 19, “Installation instructions”.
This chapter describes the aspects which are important when sizing and implementing the anchors, guides and supports.
It also contains information on:
• Thebestinstallationpositionsforthe tie rod
• Useoflateralexpansionjointsinathree-hinge system
• Installationofelbow-connected pressure balanced expansion joints
• Pretensioningalternatives
If in doubt, please make use of the advice of our specialists:[email protected]
AnchorsAll compensation systems must be limited by anchors, which have to be adequately sized if the system is to function reliably. There are four differ-ent types of anchors, each with differ-ent functions and loads.
End anchorsThese are either located at the ends of a compensated pipe system or used to separate two different compensation systems (Fig. 9.1). They are generally subjected to a high load.
The following forces act on end anchors:
• Axialreactionforce(axialexpansionjoints only)
• Adjustingforceoftheexpansionjoint or compensation system
• Frictionalforcebetweenpipeandsupports
• Otherplant-specificforces(wind,snow, weight of pipe or medium)

Sliding anchorsThese serve to guide the pipeline; they must however act as normal anchors in at least one direction, e.g. if univer-sal expansion joints are used (Fig. 9.3).The same forces act on sliding an chors as on end anchors. It should be noted in addition that a large fric-tional force is generated at the sliding anchor due to the high anchor force which is active there. This frictional force must also be taken into account when sizing the end anchor FP1.
Elbow anchorsThese separate two identical compen-sation systems at the crown of a pipe elbow.This type of anchor is a mixture of an end anchor and an intermediate an chor. The same forces must consequently be taken into account as for end anchors, in addition to the differential forces which occur with the in termediate an chors if the pipe elbows are too small.The redirection of the flow in the pipe elbow results in a centrifugal force, which must likewise be absorbed by
the elbow anchor if an axial compen-sation system is used. This force is however usually negligible.The individual force components must be added together geometrically, in order to obtain the magnitude and direction of the resulting anchor force Fres.
Fig. 9.3 Offset pipeline with universal expansion joint and one sliding anchor
Fig. 9.4 Offset system with axial expansion joints and elbow anchor
Intermediate AnchorsThese separate two expansion joints of similar construction which are nec-essary in long, straight pipe runs, and are generally only subjected to a slight load (Fig. 9.2).
The following differential forces act on intermediate anchors:• Axialreactionforce(axialexpansion
joints only) if different nominal diameters must be separated or if there are pressure differences (flow losses at throttles or butterfly valves). Axial expansion joints made by different manufacturers usually have different reaction-force effect, even if the nominal diameter is the same; this can result in considerable differential forces.
• Adjustingforceifexpansionjointsofdifferent lengths and with different adjustig rates or identical expansion joints with different movements are used.eveniftheexpansionjointsand the movements are the same, a differential force which is 30% of the adjusting force should be assumed,
since the spring rates of the expan-sion joints are subject to fluctuations in this region due to production and material tolerances.
• Frictionalforcebetweenthepipeand guides. Particular attention should be paid to this point, since the frictional forces may differ sub-stantially during operation depend-ing on the type of support.
• Otherplant-relatedforces,whichmust be taken into account when calculating the load on the anchors.
The inermediate anchor becomes an end anchor during pressure tests in a section of the pipe or if the system contains a gate valve.

Anchor forces
Axial reaction forceChapter 12, “Axial reaction force and pressure balenced designs” describes the generation and effect of the reac-tion force in detail; the calculation for-mula consequently suffices at this point.

effectivecross-sectionAincm2 (see dimension tables for axial expansion joints)Pressure p in bar (take maximum pres-sure, e.g. test pressure)
If the internal pressure is greater than the external pressure, the expansion joint will be elongated by the reaction force without anchors, whilst if the ex ternal pressure is greater than the in ternal pressure, it will be compressed.
If pressure tests are performed section by section during construction of an extensive pipe system, and if the strong end anchors are not locked in position, axial expansion joints must be protected by means of suitable stroke limiters (see special “HYDRAM-AT” range, for example), or alterna-tively the intermediate anchors must be made correspondingly stronger.
Adjusting force of the compensation systemThe axial adjusting-force rate c is specified in the dimension tables for axial expansion joints. The adjusting force is calculated as follows:

F = 0.001c ·

In hinge systems, the adjusting forces are more complicated to calculate than for axial expansion joints. Con-tains detailed instructions on how to calculate the forces and moments.
Frictional force between pipe and supportThe entire frictional force of the pipe section between the compensation system and the anchor, i.e. the sum of the frictional forces of all supports, acts on each anchor.

Other plant-related forcesIn addition to the forces generated as a direct result of the manner in which the expansion joints are installed, the anchor sizing must also take into account those forces produced by the system or the pipeline route, or by additional loads:
• Weightofpipe,mediumand insulation
• Weightofdustdepositsbothinsideand outside
• Weightofcondensate• Windandsnowloads• Forcesduetomassaccelerationin
event of an earthquake• Forcesduetopipedeformationasa
result of inadequate compensation
If pipes used for gaseous media are subjected to a water pressure test, the weight of the water must be tak-en into account additionally.
It must be remembered that the fric-tional force acts on an anchor in alter-natingdirections–asareactionforcewhen the pipe is heated up and as a tensile force when it is cooled down.
The distribution of the frictional-force components acting on the two an chors can be altered by changing the arrage-ment of the compensation sys tem along the pipe section between these anchors. If, for example, the compen-sation system is positioned directly at an anchor, this anchor (FP1) must not absorb any frictional force; the second anchor (FP2) on the other hand must absorb the entire frictional force of this section (Fig. 9.5).
If the compensation system is positioned centrally between both anchors, each anchor must absorb half the frictional force of the complete section (Fig. 9.6).

GuidesParticular attention must be paid to the pipe guides in the region of expansion joints or compensation systems; the dif-fering requirements of the compensa-tion systems must be taken into account.
Guides for axial compensationThe conditions dictated by the plant must always be taken into considera-tion when sizing the supports and cal-culating the distances between the supports. The following rules must also be observed if axial expansion joints are used:• Thefirstguideaftertheaxialexpan-
sion joint must be no more than 3xDnawayfromtheexpansionjoint, i.e. L1 ≈3·Dn(Fig.9.8)
• Thedistancebetweenthefirstandsecond supports after the expansion joint must be approximately half the normal distance between supports, i.e. L2 ≈ 0.5 · LF (Fig. 9.9)
• Thenormaldistancebetweensup-ports LF may have to be reduced if there is a risk of the pipe buckling (Fig. 9.10)

If the long intemediate pipes are in stalled in horizontal systems, they must be supported in order to prevent
excessive lateral forces from acting on the expansion joint. (Fig. 9.13).
The slip plane of the supports must always be perpendicular to the pivots of the expansion joints.

Guides for three-hinge systemsThe loads placed on the guides of three-hinge systems are only slightly greater than those placed on standard pipe guides. The only additional loads are the adjusting forces of the system, which are however usually small. specialattentionshouldbepaidto ab sor p tion of the weight of the pipe sections between the angular expan-sion joints. These sections are often long and their weight can place an ex cessive load on the expansion joints.
The examples below demonstrate load removal by means of supports and flexible suspensions.
If a plane three-hinge system is installed at a slope angle (Fig. 9.19), it is important to ensure that the pin axes are always parallel to one anoth-er and perpendicular to the support level, i.e. the axes of the expansion joints must be inclined by the angle a when they are installed.

Fig. 9.19 Inclined three-hinge system
Flexible suspensions or supports must be provided for vertical systems or systems which are flexible on all planes and for heavy loads (Figs. 9.14 and 9.15). It should be noted that bending the pipe causes additional forces on the hinge parts of the expansion joint derived from the residual elongations of the pipe system. For vacuum serv-ice or abnormal pretensioning of the expansion joints, the additional bend-ing forces placed on hinge parts may be so heavy that reinforcement is nec-essary. In this case the additional on the expansion joints forces must be specified in inquiries and orders. Fig. 9.16 Plane, three-hinge system with both

Deflection in anchor planeThe pipe is bent in approximately the manner of a beam clamped at both ends, since the anchoring transfers a significant moment (Figs. 9.24 and 9.25).Thes-bendinthepipewhichresults necessitates a much greater free length than in the first example; in
addition, much greater moments and forces are generated, and may place an excessive load on the anchoring of the expansion joint.If necessary, the load-bearing capacity of the anchoring must be checked on the basis of the additional forces and moments.Fig. 9.21 Lateral expansion joint, flexible on all
planes. Deflection in anchor plane

Installation instructions
Anchor positions for lateral expansion jointsAlmost all lateral expansion joints have two tie rods, which give them additional angular flexibility in one plane (Fig. 9.20). The same applies to lateral expansion joints flexible on all planes. Lateral expansion joints can-not be offset in the second plane, since the anchoring functions like a parellelogram in this plane (Fig.9.21).Asmentionedearlierinthe“guides”section of this chapter, there is always an uncompensated movement compo-nent, which must be absorbed by bending the pipe, when lateral expan-sion joints (double hinges) are used. The pipe can be bent in different ways de pending on the position of the anchor.
Deflection transversal to anchor planeThe pipe is bent in approximately the manner of a beam clamped at one end (Figs. 9.22 and 9.23), since the small adjusting moment of the expansion joint is insignificant. The free bending
length can thus be kept relatively short and the additional loads on the expan-sion joint remain small.

Onlylateralexpansionjointswithhinge pins located exactly above the centre of the bellows should be used. If the lateral expansion joints have tie rods, or if they have hinges located away from the centre of the bellows, it is considerably more difficult to cal-culate the bending angles, the forces and moments and the stability of the system.This pipe system must always be examined by the expansion joint man-ufacturer to ensure that it can function properly, even if no problems are apparent after the initial, rough calcu-lations.
Lateral expansion joints with more than two tie rods cannot be used in a three-hinge system.
Installing elbow-connected pressure balanced expansion jointselbow-connectedpressurebalancedexpansion joints are anchored expan-sion joints in which the axial reaction force produced by the internal pres-sure is not released.
Angular configuration of two lateral expansion jointsTwo short, lateral expansion joints are often arranged diagonally to cope with small, lateral movements on all planes or with vibrations at machine connec-tions (Fig. 9.26).In this case it is important to ensure that the pairs of tie rods belonging to the two expansion joints are offset 90° in relation to one another. This prevents the connecting pipe bend from rocking excessively, which would cause the expansion joints to fail prematurely.
Combination of lateral and angular expansion joints in a three-hinge sys-temsinceonelateralexpansionjointhasthe same kinematic characteristics as two angular expansion joints with an intermediate pipe, it is also possible to construct a three-hinge system with one lateral expansion joint and one angular expansion joint.
If the hinge system is installed in a confined space, especially if it is a
3 - dimensional system, it may be cheaper to use a combination of angu-lar and lateral expansion joints. Purely an gular systems are usually cheaper if large hinge distances are desired (greaterthan5xDn).The anchor of the lateral expansion joint must be arranged in the system so that they can be offset in the direc-tion of the angular joints (Figs. 9.27 and 9.28).The lateral expansion joint functions like a parallelogram with regard to transversal movements in a 3 - dimen-sional system.

An elbow-connection pressure bal-anced expansion joint installed between a turbine and a condenser can provide a connection which requires only a re latively small vertical distance (Fig. 9.30).
The connection on the turbine side can also be made with a rectangular crosssection.
A pressure balanced expansion joint can be used in long pipe sections to absorb larger movements (Fig. 9.31).
The movement is effected by means of an extremely small pipe offset. Unlikewiththethree-hingesystem,there is no lateral deflection which needs to be considered; a small clear-ance may be left merely in the guides directly at the expansion joints for the thermal ex pansion resulting from the distance between the axes of the two pipe runs, in order to relieve the load on the bellows.
Installing elbow-connected pressure balanced expansion jointselbow-connectedpressurebalancedexpansion joints are anchored expan-sion joints in which the axial reaction force produced by the internal pres-sure is not released.
Axial and lateral movements can be absorbed simultaneosly. An additional, angular flexibility on all planes can be achieved using special designs (see also Chapter 12, “Axial reaction force and pressure balanced designs”).
A further advantage of this construc-tion type is its compact dimensions. These enable complex movement problems to be solved in confined spaces, which also has the advantage of small connecting forces. The princi-ple apllications should now be appar-ent, namely connections for pumps, compressors and turbines in restricted spaces.
elbow-connectedpressurebalancedexpansion joints are normally
designed specially to suit particular operating and installation conditions. The ex amples described below dem-onstrate the special advantages of this construction type and indicate points which should be noted when it is installed.
If elbow-connected pressure balanced expansion joints are used for pump connections (Fig. 9.29), it is possible firstly to achieve a low-stress machine connection, which is flexible on all planes and requires little space, and secondly to decouple vibrations with small, movable masses.

Axial expansion jointsThe expansion joint is welded at one end to the pipe (1). This section of the pipe has already been secured, so that the expansion joint can be preten-sioned subsequently without it being displaced.The pipe section to be connected is lying loose in the guides (3).The pipe section to be connected is then advanced up to the point of con-tact (4) and welded to the expansion joint (5).
After welding the loose pipe, it is pulled away from the expansion joint in an axial direction, using a wrench or other suitable device, by the magni-tude of the pretension value (6).
Care must be taken to ensure that the expansion joint is not overextended (7). This section of the pipe must then also be secured, so that the expansion joint no longer draws the pipe towards it whenreleasedbythepretensioner(8).(Fig. 9.37)
PresettingPresetting is necessary in order to ex ploit the full movement capability of anexpansionjoint.eachexpansionjoint can effect movements of an iden-tical magnitude in both directions from the neutral position. The opti-mum presetting value is consequently 50% of the total movement.
The pretension as a proportion of the pipe expansion corresponds to the pretension of the expansion joint itself in the case of axial expansion joints, lateral expansion joints and angular expansion joints in a double-hinge system.
In three-hings systems with angular expansion joints this is usually the case as well; in unfavourably designed systems, however, the pipe pretension should be calculated with particular care, since it is no longer necessaryly proportional to the angular deflection of the individual angular expansion joints.
sinceitisdifficulttopretensionanexpansion joint directly when it is as sembled, it is advisable to assemble the expansion joints in their neutral positions and to pretension the com-plete pipe run later on, either by dis-placing them before securing the an chors or afterwards using an adapt-er which has been cut out.

This is possible manually if the expan-sion joint is lightweight; otherwise a suitable tool can be used. (Fig. 9.39)
Angular expansion jointsThe end anchors are secured at both ends (1). The angular expansion joints are welded or flanged in in their neu-tral position, i.e. perpendicular to the incoming pipe runs (2). The pipes to be connected are spaced at a distance corresponding to the pretension val-ues, or alternatively a pipe section cor-responding to the pretensionvalue can be cut out (3). (Fig. 9.40)
The expansion joints, which are already operating jointly, must then be pulled (or pushed) away from their neutral position by the pretensioning value (4) and rigidly connected to the pipe runs (5).This is possible manually if the expan-sion joints are lightweight; otherwise a suitable tool can be used. (Fig. 9.41)
If axial expansion joints are used, it is also possible to order them already pretensioned; this ensures that they are always pretensioned to the correct value on the building site.It is of course also possible to dispense with pretensioning if the movements are so minimal that the permissible deflection of the expansion joint in one direction from the neutral position is not exceeded.
Lateral expansion jointsThe end anchors are secured at both ends (1). The expansion joint is weld-ed in at a neutral position (2).The pipe to be connected is spaced at a distance corresponding to the pre-tension value V (3). This must be ensured by means of a movable adapter or by cutting out a pipe sec-tionwiththelengthV.(Fig.9.38)
The expansion joint is pulled (or pushed) away from its neutral position by the pretension value (4), then con-nected rigidly to the pipe run (5).

Technical characteristicsThe “multi-ply” principle is based on the idea of subdividing the pressure-bearing wall into a large number of thinner, individual plies, and thereby considerably increasing the flexibility, which is the most important character-istic of an expansion joint (cf. wire rope as opposed to steel rod).
Physical interrelationshipIt becomes apparent merely by con-sidering a simple flexural bar that if the bending and all other dimensions re main the same whilst the beam height is halved, the bending stress is likewise halved and the adjusting force of the double-ply flexural bar is reduced to just one quarter of its origi-nal value.
The principle is similar for the corru-gations of a metal bellows. The inter-relationships shown below (Fig. 10.2) demonstrate how the flexibility, pres-sure reliability and adjusting force are dependent on the most important geo-metrical parameters of the corrugation in an initial approximation (see, also Chapter 11, “Bellows design”).

The individual tight cylinders may be made of different materials if desired; this opens up various economic possi-bilities, for example, of countering cor-rosion. Material qualityusing cold-rolled strip material in only a few thicknessess – it is usually the number of plies which is varied – en ables the material to be procured in large quantities, in order to influence positively the characteristics of the raw material which are particularly im por-tant for manufactering bellows, such as dimensional tolerances, surface quality, strength characteristic va lues and formability. The desired character-istics and data are laid down in our order and inspection certificate according to en 10204-3.1/3.2 from the TÜV.
The most important materials are per-manently available in stock.
Technical characteristicsA number of highly positive expan-sion joint characteristics result from structuring the bellows with a large number of individual plies:
• Abilitytocopewithhighpressurecombined with excellent flexibility
• Largemovemencombinedwithsmall total lengths and a guaranteed number of stress cycles (normally 1000)
• Smalladjustingforcesinrelationtoother designs
• Smallbellowsoutsidediametersandconsequently small effective cross-sections for reduced loads on anchors
• Highburstingpressures–atleast 3 times the nominal pressure
The relationships take into account the number of plies; this reveals the posi-tive effect of a large number of plies in view of the aim of a high pressure reli-ability combined with good flexibility; whilst increasing the number of plies causes the pressure reliability to be increased likewise in linear fashion, the flexibility remains unaffected. Although these relationships are much more complex and less easy to formu-late in reality, the potential for adapt-ing the multi-ply expansion joint opti-mally to specific operation conditions is readily apparent.
Bellows structureThe multi-ply bellows is made using a multi-ply cylinder package.The multi-ply cylinder package is turned into a multi-ply bellows by pressing out toroidal corrugations (Fig. 10.3). The plastic stretching of the material which occurs during this process is also a reliable test of the quality of the longitudinal seam of the cylinder.

Safety principleIn addition to the safety which the ex pansion joint user is guaranteed by the reliable design and conscientious manufacturing, the multi-ply HyDrA expansion joints offer a notable ad vantage with regard to safety, namely the check hole for indicating leaks (Fig. 10.4).
If the ply of the multi-ply expansion joint which is in contact with the medi-um develops a leak, for example as a result of corrosion, a weak stream of the conveyed medium is choked out of the expansion joint through the seper-ate cylinders; the onset of damage is indicated by a slight leak at the “check holes” in the bellows neck (covered by rings). The pressure reliabi lity and operation of the expansion joint are maintained in such cases for a lengthy period of time (weeks or months). It is therefore not necessary to replace it immediately; this can be left until a lat-er date which is more convenient to the operator. A replacement expan-sion joint can be procured within the
normal delivery period with out the need for any special measures.There is no need to store spare expan-sion joints.
Benefits and safety of multi-ply expansion joints
Economic benefitsThe large movements of the multi-ply HyDrA expansion joints means that only a few expansion joints are neces-sary to compensate the movements which occur, such as thermal expan-sion, and that the costs are reduced accordingly (fewer inspection shaft con structions are required, for example).The more compact dimensions of the multi-ply bellows result in shorter total lengths of the expansion joints and in reduced protrusion of the anchoring of hinged expansion joints as well as small outside diameters of any outer protective sleeves which may be ne cessary. This again results in cost savings with regard to the shaft con-structions, since these constructions can manage with much smaller di men sions.The smaller adjusting forces of the multi-ply HyDrA expansion joint reduce the expenditure for anchors, and thus allow effective, economical
compensation in a small place, e.g. hinge systems with very short leg lengsts.If they are planned correctly and in stalled in accordance with instruc-tions, multi-ply HyDrA expansion joints shield machine connections from forces and moments and damp-en vibrations; they thus help to main-tain trouble-free operation and reduce repair costs.A number of different bellows materi-als can be used to counter the risk of corrosion, providing they are suffi-ciently formable – the most economi-cal method is to manufacture only the ply which is in contact with the aggressive medium using the corro-sion-resistant material, which is gen-erally extremely expensive, and to make the remaining plies using the stainless steel 1.4541 employed as standard. It is however essential to ensure that the different bellows mate-rials can be welded to one another and to the connection parts, or alter-natively that lap-joint flanges can be used.

Noise proofingmulti-ply bellows have a movement hysteresis due to mutual effect of the plies on one another and to the effect of friction.
The dampling which results from energy consumption has an extremely positive effect as regards isolation against structure-borne noise. multiply bellows can reduce this noise by up to 20dB in the same way as rubber ele-ments.
The outstanding characteristics of multi-ply HyDrA expansion joints have for many years made them the best, if not the only, answer for many practical applications, especially when high pressures are involved.
On the basis of our many years of experience, we can state that sponta-neous bursting of HYDRA multi-ply bellows is not possible under any circumstances.
Permanent leakage monitoringWhen used in plants with toxic, flam-mable, explosive or other critical media, multi-ply HyDrA expansion joints can be monitored permanently for leaks without any risk of the critical medium escaping if damage occurs.The check hole is guided into a closed, toroidal chamber, to which a pressure measurement instrument is connected (Fig. 10.5). The instrument outputs an alarm if the pressure rises, so that any onset of damage to the inner ply is in dicated at absolutely no risk. even large pipe systems, such as gas net-works, can be monitored completely, reliably and economically by this method.

BellowsDesign
The problemA corrugated metal bellows must meet two contradictory demands – namely pressure reliability on one hand and flexibility with regard to relatively large, alternating move-ments on the other hand – giving almost equal priority to both.
This is a major difference – also as far as the calculations are concerned – between the metal bellows and other pressure-bearing components, such as vessels and pipes, where pressure reliability is essential, whilst other, alternating loads which are imposed on them generally play a subordinate role and are only calculated approxi-mately as addition loads.
But the aim when designing an expan-sion joint bellows is to establish the shape and size which allow the two demands to be met optimally in both technical and economic terms.
According to the latest state of the art – which is based on several decades of experience – the construction princi-ple of double and multi-ply expansion joints provides the best basis for achieving an optimised system.
On the other hand, using several plies further complicates the already diffi-cult calculation of the lyre-shaped bel-lows corrugation, which has the shape of a doubly-curved shell. A reliable method of designing and sizing ex pan-sion joints is however indispensable, since the safety of the plant and the operating personnel may depend on it.
Sowehavedevelopedanindepend-ent calculation method. This calcula-tion method is basically founded on en 13445-3 and en 14917 and was complemented by supplements of operational experience and test results.
The method was examined by an independent third party inspection agency (TÜV); an equivalent complete safety level in the sense of directive 97/23/eG was demonstrated.
The theoretical basisThis calculation method applied in standards (en 13445, en 14917,...) and rules(EJMA,ASME,...)isfoundedonthe calculation method which was developed by Anderson for the Atomic EnergyCommission,USAandpub-lished in the year 1964/65.
This method takes a flat, non-curved plate strip with a height w, corre-sponding to the height of the corruga-tions, as a simplified, substitute model for a bellows half-corrugation (Fig. 11.1). The equations required to calcu-late this substitute model are set up, and then corrected with factors which take into account the effect of the real shell shape of the bellows corrugation.

Service lifeBased on test results and considering the correction factor a fatigue curve specific to the manufacturer was established. The determination of this particular curve followed en 13445-3 and en 14917. Based on the best fit
curve a service-life curve is deter-mined, which covers at least 98 % of the test results. It is called “design-curve” and is the basics for the expan-sion joint design (Fig. 11.2).
Anderson provides the correction fac-tors in the form of a graph; they have been determined analytically by means of shell equations and take the laws of similarity into account. The method provides clear equations in line with the simplified, yet elegant, formulation(Fig. 11.1).
The equations can principally be used as the basic equations for calculating the bellows, though strictly speaking they only apply to single-ply bellows with u-shaped corrugations (parallel flanks) and with a constant wall thick-
ness over the entire corrugation; bel-lows with more than one ply can be calculated approximately using these equations, providing the number of plies is not too high (between 2 and 4) and the overall wall thickness is small in relation to the given corrugation height.
The Witzenmann method
The essential completions and exten-sions of the calculation method acc. to en 13445 introduced by us are:
•Repealofthelimitof5pliesby introducing a correction factor
•Modificationofthefatiguelifecurve evaluated on tests
• Determinationofworkingspringrateconsidering the real material behav-iour as well as other effects such as friction
• Modificationoftheformulaforcol-umn instability considering the influ-ence of movement

Working spring rate of bellowsThe spring rate of a bellows, which depends on the geometry (in particu-lar wall thickness and convolution height) and the material of the bel-lows, is required for the determination of several properties of the bellows and is no clear, linear order.
The stiffness of a bellows can be cal-culated within the elastic range with sufficient accuracy (see en 13445-3). It is valid only for small axial move-ments and deviates from the linear course (plastic range, line BC) when the axial movement increases.With great efforts is possible to deter-mine the real working spring rate by measurement.
That’s why we formulated an equation for the working spring rate by the analysis of internal measurings in combination with theoretical models.
With this equation it is possible – in accordance with the results of meas-
urement – to calculate the working spring rate in relation to the axial movement.
All supplementary influences such as pressure, friction or plastic deforming were taken into account in this equa-tion.
It is recommended for the practical use to apply the real adjusting force rate (AC) for the calculation of forces and moments.
StabilityThe performance of a bellows (pres-sure resistance, fatigue life) can be decreased considerably by instability. Therefor a reliable calculation of the critical internal pressure is very impor-tant. There are to kinds of instability:
Column instability, which only applies to bellows with internal pressure, is defined as a strong lateral shift of the bellows median line and occurs at bellows with a relative great ratio of length and diameter. To determine the critical pressure we have considered both the static pres-sure and the effect of movement.
Inplane instability – also called local instability – occurs at relative small ratio of length and diameter and is defined as slipping or twisting the plane of one or several corrugations against the straight axis of the bellows.

Axialreaction force
A longitudinal force with the magni-tude Fl = a·p generally prevails in a pressurized pipeline, where a repre-sents the pipe cross-section and p the pressure difference (internal/external). The reaction force is generated by the axial pressure components, which act on a projected cross-section at the end of a pipe section (Fig. 12.1).
Axial expansion jointsIf a flexible, non-anchored, axial ex pansion joint is used, the reaction force is released, i.e. there is no rec-tion in the pipeline in the form of a longitudinal force; the reaction force must be absorbed at both ends of the pipe section by means of anchors.
Sincetheaxialexpansionjointnor-mally has a mean bellows diameter which is greater than the inside dia-meter of the pipe, the force which must be taken into account when de signing the anchors is slightly high-er (Fig. 12.2).

A = effective bellows cross-section p = gauge pressure
The axial reaction force is obtained in kn, if A is specified in cm2 and p in kn/cm2 (1kn/cm2 = 100 bar; see Chapter 4, “Compensation types”, Fig. 4.6). The effective bellows cross-section specified in the dimension tables for the axial expansion joints can be well approximated with the aid of the mean bellows diameter.

The problem which results when flexibly supported aggregates must be connected via axial expansion joints is apparent – the aggregate is tilted due to the dynamic effect (see Chapter 13).
A force part is derived from the differ-ence between the cross-sections of the bellows and the pipe A = A – a; it is guided through the pipe as a longitu-dinal reaction force from the expan-sion joint to the anchor (Fig. 12.3).
Anchored expansion jointsexpansion joints are fitted with an chors in the form of spherically sup-ported tie rods or hinged sections, in order to guide the longitudinal force via the expansion joint from one pipe connection to the next. As far as the axial reaction force and the longitudi-nal force are concerned, a pipe with a hinged expansion joint behaves in the same manner as a continuous pipe; no additional load is placed on the anchors or guides by the axial reaction force.
Pipe connection loadThe reaction force acts on machines and aggregates via the pipe connec-tors; different pipe connections loads result according to the type of pipe connection. No other loads are consid-ered here!

joints which are adequately sized to cope with the total movement are nec-essary.
Pressure balanced axial expansion jointsThese designs compensate the axial reaction force by means of an addi-tional pressure chamber, which can be either circular or toroidal and which is connected to the two diverging ends of the working bellows in opposite directions (Figs. 12.10 to 12.13).

Pressure balanced designsSincehigheroperatingpressuresandlarger diameters can cause the axial reaction force to reach a level which makes it either uneconomical or im possible to size the anchors, anchored expansion joints (either angular or lat-eral expansion joints) are normally used to absorb the thermal expansion; they always require the pipeline to be rerouted however, since their design does not permit axial movement.
If it is undesirable to reroute the pipe-line, or if it is impossible for reasons of space, straight-section tie rods or pressure balanced, axial expansion joints can be used instead, depending on the plant-specific circumstances.
pressure balanced, axial expansion joints are relatively complex construc-tions, which should only be used if other, more economical alternatives are not viable. One possible reason for using them might be that they are de signed to absorb additional, lateral movements, e.g. vibrations.
The elbow-connected pressure bal-anced expansion joint is a versatile variant of the pressure balanced design; in contrast with the designs described above, it requires the pipe-line to be re routed, but in exchange provides flexibility on all planes.
Straight-section tie rodsContainers which must be connected together by a straight pipe – often at great heights – cannot absorb any sig-nificant axial reaction forces. An axial expansion joint and a straight-section tie rod which is adequately sized to cope with the reaction force may be the best answer (Fig. 12.9). The tie rods are almost always fixed and fitted by the customer. The full benefit is only obtained from the straight-sec-tion tie rod if the tie rods are located outside the insulation, in other words if they remain “cold”, and if they are fitted in the centre of the container.
If differences in height must be com-pensated at the same time, hinge- sup-ported anchors and axial expansion

The simplest type is the elbow-con-nected pressure balanced axial expan-sion joint with slight lateral flexibility. (Fig. 12.14)
One example of how this design can be used in practice is to link containers if only small vertical movements are involved, or – if the vertical movement caused by the time gap is sufficiently small. (Fig. 12.15)
Otherwise designs with greater lateral flexibility, provided by two working bellows, must be used instead. (Fig. 12.16).
elbow-connected pressure balanced lateral expansion joints can also be used in 3-dimensional systems if they are fitted with gimbal hinged expan-sion joints for flexibility on all planes.
Other designs based on the same prin-ciple are also possible, and have been implemented in numerous cases; in the final analysis, the design is dictat-ed by the requirements of a specific application. Our multi-ply bellows de signs with their low adjusting forces have proved extremely useful, since either one or two additional bellows must now be moved as compared with a normal axial expansion joint. The axial adjusting force cannot be compensated in the manner of the reaction force, but remains as a load on the anchors.
Elbow-connected pressure balanced expansion jointsThis design exploits a rerouted pipe-line by incorporating the expansion joint exactly at the “elbow”. The axial reaction force is then compensated by means of an additional bellows, which is located outside the actual pipe and acts as a piston, thereby transferring its counter-force to the pipe to be con-nected via tie rods (Fig. 12.14).

General aspects
Hydrodynamic machines, piston engines and similar aggregates gener-ate vibrations with differing frequen-cies and amplitudes according to their construction type as a result of the rotating or to-and-fro movement of their masses.
The pipes connected to them are con-sequently also made to vibrate, which can lead to material fatigue and dam-age; damage is inevitable if the reso-nance occurs in the connecting pipes.High-frequency vibrations moreover
have an unpleasant side-effect in the form of noise, whilst low-frequency vibrations can be passed on via the foundations and the ground and cause damage in neighbouring construc-tions.
The aggregates are flexibly supported and their connecting pipes decoupled by means of flexible pipe elements, in order to prevent vibration damage and noise propagation. metal hoses and expansion joints are used for this pur-pose.
The most important criteria which should be considered when selecting the best flexible element are as follows:
• Dimensions of pipe connectors Drilling template of flanges Diameter and thickness of weld ends Bolting (types and dimensions) Specialconnections
• Operating data pressure Temperature Flow velocity medium (possible impurities)
• Permissible forces and moments Acting on the pipe connection Acting on the entire aggregate (stability)
• Thermal expansion, if this must also be absorbed
• Vibrations (sustained vibrations) Direction Amplitude Frequency
• Space available for installing flexible elements
• Anchors and guides for the outgoing pipes (feasible alternatives)

practically no load is placed on the pipe connector by the reaction force if axial expansion joints are used.
If lateral forces occur, the permissible connector loads should always be checked, especially if lateral expansion joints – which can only move in lateral direction due to their anchoring – are to be installed. HyDrA lateral expan-sion joints with multi-ply bellows have relatively small lateral adjusting-force rates; these rates may nevertheless be
to high for types designed for high operating pressures, due to the fric-tional-force part, or for types where the total length is too short, especially if thermal expansion must also be absorbed.
The medium which is conveyed also has an influence on the choice of ma terials if it is aggressive or contains aggressive components (see Chapter 5,“Selectinganexpansionjoint”).
Significantvibrationswithamplitudesof 0.1 – 0.5 mm are generated primarily at piston engines due to the to-and-fro movement of their masses. Turbines, centrifugal pumps and turbo-com-pressors usually only generate vibra-tions with very small amplitudes – often in the audible frequency range – which are due to unbalance or to pres-sure differences at the blades.
The connections used for the vibra-tion elements normally take the form of flanges according to DIn 2501 or equivalent standards; special flange de signs are often necessary for engines due to the lack of space available.
The nominal pressure of the flexible pipe element can be determined from the operating data (pressure and tem-perature), taking the reduction factor into acount; this data also effects the choice of materials for the corrugated section and for the connection parts (seeChapter5,“Selectinganexpan-sion joint”).
The operating pressure is used addi-tionally to calculate the axial reaction force, which acts as a longitudinal force in all pressurized pipes, but which is released if an axial expansion joint is used, thereby placing a direct load both on the next support and on the aggregate (Fig. 13.1). This topic is dis cussed in more detail in Chapter 12, “Axial reaction force and pressure bal-anced designs”.
It should be noted that the axial reac-tion force which is released acts on the interior wall of the body which is op posite the pipe connector (Fig. 13.2), and that the flexibly supported aggregate may be tilted or displaced excessively, depending on the magni-tude of the force. The position of the pipe connector is also important in addition to the weight of the machine and the elastic parameters of the sup-port, since it determines the direction of the force and thus also its permissi-ble magnitude.

Flexible elements for absorbing vibrations
515
Flexible elements for absorbing vibrationsevery all-metal, flexible pipe element we supply for connecting to vibrating aggregates is pressure and tempera-ture-resistant and absolutely leak tight; our elements do not age, and if chosen and fitted correctly have a practically unlimited service life.
Different types of flexible elements can be used, depending on specific requirements (Figs. 13.3 and 13.4). The table below lists the various possible designs and outlines the applications to which they are best suited for (Fig. 13.5). Deviations from the specified approx. values are possible on the case-to-case basis.
In all machines the highest amplitudes are thus encountered in a plane which is perpendicular to the pivot. The re quirements which must be met by the flexible elements, and on which the choice must be based, can there-fore differ considerably according to the position of the pipe connections.
In addition to the vibration values dur-ing continuous operation, which necessitate highly durable elements, moment amplitudes which are often up to five times as high are likely dur-ing start-up, especially if the ma chine must pass through a critical speed range. These wider limit stops can generally be ignored when designing the flexible elements, since they are only allowed to occur for extremely short periods in the interests of gentle machine operation.
The first natural frequencies of the flexible elements should be higher than the excitation frequencies of the machine and sufficiently far away from them.
The elements used for noise isolation, on the other hand, must have natural frequencies which are lower than the noise frequency, which is almost bound to be the case; these elements can only provide insulation against structure-borne noise. Any noise which is conveyed in the medium (e.g. water) is not normally dampened to any significant extent by flexible con-necting elements.
Braided HyDrA metal hoses and multi-ply HyDrA expansion joints, with their special design principle, have a noise isolating effect, which has been verified by means of tests. The multi-ply HyDrA axial expansion joints, for example, can provide insu-lation against structure-borne noise up to 20dB. They are thus far superior to single-ply designs.
Impulse pressures in the medium, which may also form the pipes or cause them to vibrate, cannot be elim-inated using flexible elements; viscous dampers must be used instead.

Thermal expansionIf thermal expansion must be absorbed in addition, the permissible values can be calculated in the usual way(seeChapter5,“Selectinganexpansion joint”), i.e. sustained vibra-tions need not be taken into account. This also applies to lateral movement, which can be calculated for axial ex pansion joints with single bellows according to the equation below:
Equivalent lateral movement
(13.3)
Lateral adjusting-force rate
(13.3)
Axial adjusting-force rate taken from dimension tables for axial expansion joints c in n/mm.
The likely pipe connection load can be determined on the basis of the adjusting-force rate (see Chapter 9, “positioning an expansion joint”).
Guides and anchorsThe diverting pipes of vibrating aggre-gates, which are decoupled by means of axial expansion joints, must be sup-ported directly downstream of the ex pansion joint, whereby it is impor-tant for the fixture to be indipendent of the vibrating foundation. A support in the form of a fixed or sliding anchor must be sized so that it is capable of absorbing the axial reaction force in addition to the ad justing forces (Fig. 13.8). A sliding an chor should be used if lateral thermal expansions must be absorbed at the same time (Fig. 13.9).
Axial expansion jointsThe most economical element with the simplest design is the axial expan-sion joint; it can be used whenever the
aggregate is able to withstand the axi-al reaction force specified in the table below for a common range (Fig. 13.6).

sion joints can be supplied with one-piece, inner sleeves with a reduced diameter.
Metal hosesIf the normal diameters are sufficiently small at high pressures, i.e. up to approx. Dn 100, braided metal hoses, where the braid absorbs the reaction forces, provide a potential means of absorbing vibrations. If they are inte-grated in a 90° bend, they can absorb vibrations on all planes whilst producing only small adjusting forces (Fig. 13.11).
Lateral expansion jointslateral expansion joints are used at vibrating aggregates if the operating pressures are so high that an axial ex pansion joint can no longer be used due to the axial reaction force and a metal hose is no longer suitable on account of the specified connection diameter or other parameters.
If the vibrations only occur in one plane, perpendicular to the axis of the pipe connector, a single expansion joint is sufficient, providing it is flexi-ble in all directions in this plane. A design with spherically supported tie rods is suitable (Figs. 13.12 and 13.13).
Natural frequenciesThe natural frequencies in the axial and radial directions are specified for the standard range of “axial expan-sion joints for low pressure”. They only ap ply if the expansion joints are used for gaseous media. If other axial ex pan sion joints are to be used to ab sorb vibrations, the calculation of the natural frequency must take into ac count whe ther a gas or liquid is to pass through the expansion joint, since this frequency also depends on the conveyed medium. We can calculate the natural frequencies for you on request.
Inner sleeveThe standard design of inner sleeves are not suitable for the use in vibrating expansion joints, since they impede the lateral movement. If inner sleeves are necessary, e.g. in conjunction with high flow velocities (see Chapter 5, “Selectinganexpansionjoint”)orabrasive impurities in the fowing medium, specially designed expan-

Elbow-connected pressure balanced expansion jointselbow-connected pressure balanced expansion joints may be the best answer, since they can effect 3-dimen-sional vibrations on all planes with a smaller vibrating mass (Fig. 13.16).
This adapted special design is general-ly somewhat more expensive than the arrangement shown in Fig. 13.15.
If 3-dimensional movements occur in all directions, a second expansion joint must be installed perpendicular to the first. The additional expansion joint should be either an angular ex pansion joint (Fig. 13.14) or a lateral expansion joint (Fig. 13.15), depending on the magnitude of the vibration amplitudes and on any thermal ex pansion which must be absorbed. If an angular expansion joint is used, it must be installed so that it can work together with the lateral expansion joint, i.e.the pipe bend must be able to effect rocking movements, and the lateral expansion joint must be designed to permit rocking move-ments at the associated flange.
If a second lateral expansion joint is used as the additional joint, the an chors of the two expansion joints must be arranged at 90° in relation to one anchor (Fig. 13.15).

The permissible vibration amplitude for sustained vibrations is approxi-mately 5% of the movement values on one plane specified in the dimension tables for 1000 stress cycles (, , ) for all expansion joints.
With all types of flexible element should be assembled as close as pos-sible to the vibrating aggregate, in order to prevent additional movement.
An anchor or a guide support which is independent of the vibration bed should be installed directly after the compensating element, in order to reduce the free-swinging mass to a minimum. This largely precludes the risk of self oscillation.
Noise-isolated expansion jointsIf lateral expansion joints must be used on account of the operating conditions as described above, the insulation does not necessarily prevent transmis-sion of structure-borne noise, since the anchoring still transmits the noise despite the use of multi-ply bellows.
lateral expansion joints with braided anchors (Fig. 13.17) can be used in such cases if the nominal diameter is small, or alternatively specially devel-oped HyDrA lateral expansion joints (LSandLRStypes)forlargediame-ters; the latter have tie rods with noise-isolating supports and thus ensure that the machine connection has the necessary noise isolation. The insulating pads made of stainless-steel wire which are used to support the tie rods are resistant to ageing and tem-perature, and are therefore able to maintain their technical characteristics almost entirely throughout the operat-ing time, even at high temperatures (Fig. 13.18).

manufacture
expansion joint manufacturing neces-sitates a mastery of two crucial proce-dures – bellows forming and welding engineering.
Bellows formingThe bellows manufacturing process begins in the Witzenmann factory by making single, double or multi-ply cyl-inders using a readily formable mate-rial – predominantly austenitic, stain-less stell 1.4541.
The individual cylinders are made of thin strips (0.1 to 2 mm) or plates, which are given a longitudinal seam weld with a welding factor of 1. We have suitable, high-quality machines and welding methods at our disposal. multi-ply bellows are manufactured from cylinder packages (Fig. 14.1).
We use two basic methods to form the cylinders or cylinder packages into expansion joint bellows, whereby toroidal corrugations must be formed; the choice of method (hydraulic or mechanical) depends on the bellows geometry.
The hydraulic method entails applying a special hydraulic fluid from the inside, and under high pressure, to a cylinder section which has been divid-ed up by means of external and inter-nal tools. A corrugation is produced when the cylindrical section is stretched in the circumferential direc-tion as a result of the internal pressure which is applied; the material only overstretches and solidifies according to the change in the geometry, and requires no after-treatment. This method is very gentle on the material. If desired, several corrugations can be formed simultaneously using the same principle, which makes this mehod especially economical if large quantities are involved.

sion joint design, the dimensions and the combination of materials. It is essential for the connection seam to be designed so that the expansion joint remains absolutely leak tight throughout its long period operation.
The most suitable economic method should always be used to make weld seams; methods such as TIG, mIG, mAG and submerged-arc welding, which are automated to a large extent, are also employed. These methods have been well tried and tested, and are comprehensively backed up by welding procedures. Welding work is always performed by qualified weld-ers on the basis of predefined parame-ters. We apply the same care to the other weld seams, e.g. at the anchor-ing of the hinged expansion joints, some of which are located in the force flow and are therefore required to be of a correspondingly high quality.
Testing and monitoringTests are carried out to back up the quality of our expansion joints, paral-
lel to the manufacturing process and independently of the manufaturing personnel. The most important test steps and inspections which we per-form in standard situations are des-cribed below.
Standard incoming inspectionsmaterials are subjected to an incom-ing inspection when they arrive at our factory; the scope of the inspection may differ according to the intended application.
Great importance is always attached at Witzenmann to the the strip mate-rial, which establishes whether or not stipulations laid down in our order specifications have been met:• Certification• Marking• Materialanalysis• physicalmaterialvalues• Dimensions/tolerances• SurfacequalityThe strip material is then given an official inspection certificate according to en 10204 - 3.1.
Elastomer forming is a variation of the hydraulic bellows-forming method, whereby the elastomer pad performs the task of the hydraulic fluid. The pad, which like a liquid is incompressi-ble, is pressed outwards by a flexible tool, thereby forming the corrugation, which is then final-formed by recom-pression. This method, where the indi-vidual corrugations are manufactured one after the other, is suitable for small and medium diameters up to approximately Dn 1200. It can also be used to form cylinders with thick walls, especially if they are made up of many plies. High-force presses are available up to 1200 t.
The mechanical method which can be applied is a type of roll forming, and is used primarily for large diameters. Severalrollformingtoolssimultane-ously form the bellows in a single process in an machine developed by Witzenmann and constructed using our own machines. This method has been optimized and adjusted so that it can also be used to manufacture dou-
ble and multi-ply bellows.All the expansion joint bellows made by Witzenmann are based on cylinders with a longitudinal seam weld and without circumferential seam welds at the corrugation.
Other sufficiently formable materials, for which we have accumulated com-prehensive know-how, can also be used to manufacture bellows in addi-tion to the austenitic, stainless steel 1.4541 mentioned above, if the appli-cation so demands.
Welding engineeringWelding engineering is just as crucial to us as bellows forming. The above-mentioned longitudinal seam of the cylinder, which must survive the form-ing process without damage, is partic-ularly important, together with the connection weld seam, which must join the bellows and the connection parts together pressure-tight.
The nature of the connection weld seams differs according to the expan-

• Hesniffingmethod A gas mixture comprising nitrogen and helium is applied to the sealed, clamped expansion joint (pressure approx. 2 bar), and the expansion joint sniffed at all critical points with an He probe (leakage rate less than 10-5 mbar l/s).
Pressure testrandom samples of expansion joints in the same series are subjected to a pressure test in a test press. A stable inner pipe is clamped pressure tight during the pressure test to reduce the axial forces in conjunction with large diameters and high pressures. (If the available, standard testing facilities are inadequate due to extremely high reaction forces, we recommend per-forming the pressure test for the ex pansion joint together with that for the plant).
The expansion joint must not have any leaks or any formings which could give rise to doubts regarding safety.
Dimensional inspectionThis checks the dimensional toleranc-es, in particular with regard to the installation and connection dimen-sions.
Visual inspectionThis checks for visible defects or dam-age, especially to the corrugations of the bellows.
Tests and inspections, including the associated documentation, over and above the scope of those described here are possible; the necessary facili-ties are available; the scope of the tests should always be the subject of very careful thought and restricted to the necessary minimum for the partic-ular application, since the costs of such tests may be extremely high and may easily exceed the value of the expansion joint.
Manufacturing surveillanceThe manufacturing process is con-stantly monitored by the company supervisory staff (foremen); in addi-tion, the following random checks are performed by the quality department:
• Validworkinstructionsatworkplace• Currentformingparametersfor
bellows manufacture• Validweldingparametersfor
cylinder longitudinal seams and connection seams
• Correctweldingfillers• preheatingtemperatures• Dimensionaltolerancesof
components and assemblies
If any special requirements which must be met, accompanying inspec-tions may be perdormed by the quali-ty department parallel to the manufac-turing process.
Standard final inspectionsThe final inspections described below are performed for the finishes expan-sion joints before they are delivered; they can be considered to form part of the production process and do not entail any additional costs. They are documented internally. Certification of for these inspections can be provided at cost price, if this is agreed when the order is placed.
Leak tightness testAll expansion joints with welded and parts are tested for leaks. Different methods are used according to the construction type, size and application of the expansion joint.
• nitrogenunderwater The expansion joint is clamped in a test tank between two sealing plates and filled with nitrogen, pressure 2-4 bar; the tank is then flooded with water. After a suitably defined hold time, it should not be possible to de tect any bubble cavitation (leak-age rate less than 10-4 mbar l/s).

marking
Our expansion joints are normally giv-en a permanent identification plate made of stainless steel, which con-tains the following information as a minimum:• HYDRA.witzenmanngmbH; D-75175 pforzheim• year/fab.no/pos• type,pn,Dn,movement• length• const.yearexpansion joints without connection parts (compensation bellows) are giv-en a sticker or tag instead of an identi-fication plate, or inscribed with a felt-tip pen.
Flanges and weld ends are marked separartly, the data being embossed. Flanges: Dn/pn/material/manufactur-er’s identification markWeld ends: Dn/material/manufacturer’s identification mark
expansion joints in the low-pressure series do not normally have an identi-fication plate, and their flanges and weld ends are not marked. In the case of expansion joints requiring accept-ance, the parts used and the expan-sion joints are marked (identification plates) as agreed in the specification. The pretensioners and the transporta-tion safety guards, which must be removed after the expansion joint has been installed, have a red marking (indicated by additional stickers in a contrasting colour).
Corrosion protection
Standard designsThe bellows of our expansion joints, with the exception of a few special designs, are made exclusively of stain-less steels and do not normally require any type of corrosion protec-
tion; the same applies to connection parts made of stainless steel.The ferrite steel sections of the expan-sion joints, such as flanges and anchoring (not weld ends) are protect-ed ex ternally with a rust primer for transportation and short-term storage on the building site. Weld ends are either likewise painted or spray-oiled, depending on the construction type of the expansion joint. If they are paint-ed, the welded area is masked. All fer-rite steel sections are oiled from the inside where possible.
Special designsThe corrosion protection of the steel sections can be extended by agree-ment for special applications, or if requested by the customer; either a special paint, a plastic coating or gal-vanization may be used.
Packaging
Standard packagingunless otherwise agreed, the expan-sion joints are supplied with shock proof packaging in a box, in a box on
a pallet or clamped loose on a pallet, depending on their size and weight.Only hinged expansion joints, whose bellows require protection, are nor-mally clamped loose on pallets. The bellows protection, comprising corru-gated cardboard and sheet metal, pre-vents damage from minor shocks and weld splatters. large expansion joints are not packed.
Transportation safety guardsTransportation safety guards are fitted in cases where they are necessitated by heavy connection parts; they main-tain the size and form of the expan-sion joints during transportation and prevent them from vibrating.If metal parts must be welded or screwed on for this purpose, they are identified by red paint (this indicates that they must be removed after installation).
Special packagingcan be provided by agreement either by Witzenmann or by specialised sub-contractors.

Fig. 16.1 Axial thrust in a pipe with an axial expansion joint
•Removetheclampingyokeand transport retaining fit-tings after installation – not before
•Makesurethatthefixedpoints at the ends of the section of pipe containing an expansion joint are of adequate capacity. These must be able to resist the axial thrust, which can be very large, and also the adjusting force of the expansion joint, plus the friction forces of the pipe supports (see Fig. 16.2)

Corrosion resistance
Appendix B – GeneralFlexible metal elements are basically suit-able for the transport of critical fluids if a sufficient resistance is ensured against all corrosive media that may occur during the entire lifetime.
The flexibility of the corrugated elements like bellows or corrugated hoses generally require their wall thickness to be consider-ably smaller than that of all other parts of the system in which they are installed.
As therefore increasing the wall thickness to prevent damages caused by corrosion is not reasonable, it becomes essential to
select a suitable material for the flexible elements which is sufficiently resistant.
Special attention must be paid to all pos-sible kinds of corrosion, especially pitting corrosion, intercrystalline corrosion, crev-ice corrosion, and stress corrosion crack-ing, (see Types of corrosion).
This leads to the fact that in many cases at least the ply of the flexible element that is exposed to the corrosive fluid has to be chosen of a material with even higher cor-rosion resistance than those of the system parts it is connected to (see Resistance table).

Appendix B Corrosion resistance
Types of corrosion According to EN ISO 8044, corrosion is the “physicochemical interaction between a metal and its environment that results in changes in the properties of the metal, and which may lead to significant impairment of the function of the metal, the environ-ment, or the technical system, of which these form a part. This interaction is often of an electrochemical nature”.
Different types of corrosion may occur, depending on the material and on the corrosion conditions. The most important corrosion types of ferrous and non-ferrous metals are described below.
Uniform corrosion A general corrosion proceeding at almost the same rate over the whole surface. The loss in weight which occurs is generally specified either in g/m2h or as the reduc-tion in the wall thickness in mm/year.
This type of corrosion includes the rust which commonly is found on unalloyed steel (e. g. caused by oxidation in the pres-ence of water).
Stainless steels can only be affect by uni-form corrosion under extremely unfavour-able conditions, e.g. caused by liquids, such as acids, bases and salt solutions.

Appendix B Corrosion resistance
Pitting corrosionA locally limited corrosion attack that may occur under certain conditions, called pitting corrosion on account of its appear-ance. It is caused by the effects of chlorine, bromine and iodine ions, especially when they are present in hydrous solutions.
This selective type of corrosion cannot be calculated, unlike surface corrosion, and can therefore only be kept under control by choosing an adequate resistant material.
The resistance of stainless steels to pitting corrosion increases in line with the molyb-denum content in the chemical composi-tion of the material.
The resistance of materials to pitting cor-rosion can approximately be compared by the so-called pitting resistance equiva-lent (PRE = Cr % + 3.3 · Mo % + 30 N %), whereas the higher values indicate a bet-ter resistance.
Intergranular corrosionThese deposit processes are dependent on temperature and time in CrNi alloys,
whereby the critical temperature range is between 550 and 650 °C and the period up to the onset of the deposit processes differs according to the type of steel. This must be taken into account, for example, when welding thick-walled parts with a high thermal capacity. These deposit-

Fig. B.2: Sectional view (50-fold enlargement).
Appendix B Corrosion resistance
related changes in the structure can be reversed by means of solution annealing (1000 – 1050 °C).
This type of corrosion can be avoided by using stainless steels with low carbon con-tent ( 0,03 % C) or containing elements, such as titanium or niobium. For flexible elements, this may be stabilized material qualities like 1.4541, 1.4571 or low-carbon qualities like 1.4404, 1.4306.
The resistance of materials to intergranu-lar corrosion can be verified by a stand-ardized test (Monypenny - Strauss test according to ISO 3651-2). Certificates to be delivered by the material supplier, proving
resistant to IGC according to this test are therefore asked for in order and accept-ance test specifications.
Stress corrosion cracking This type of corrosion is observed most frequently in austenitic materials, sub-jected to tensile stresses and exposed to a corrosive agent. The most important agents are alkaline solutions and those containing chloride.
The form of the cracks may be either transgranular or intergranular. Whereas the transgranular form only occurs at temperatures higher than 50 °C (especially in solutions containing chloride), the inter-granular form can be observed already at room temperature in austenitic materials in a neutral solutions containing chloride.At temperatures above 100 °C SCC can already be caused by very small con-centrations of chloride or lye – the latter always leads to the transgranular form.
Stress corrosion cracking takes the same forms in non-ferrous metals as in auste-nitic materials.

Appendix B Corrosion resistance
Damage caused by intergranular stress corrosion cracking can occur in nickel and nickel alloys in highly concentrated alkalis at temperatures above 400 °C, and in solu-tions or water vapour containing hydrogen sulphide at temperatures above 250 °C.
A careful choice of materials based on a detailed knowledge of the existing oper-ating conditions is necessary to prevent from this type of corrosion damage.
Crevice corrosionCrevice corrosion is a localized, seldom encountered form of corrosion found in crevices which are the result of the design or of deposits. This corrosion type is caused by the lack of oxygen in the crev-ices, oxygen being essential in passive materials to preserve the passive layer.
Because of the risk of crevice corrosion design and applications should be avoided which represent crevice or encourage deposits.
The resistance of high-alloy steels and Ni-based alloys to this type of corrosion increases in line with the molybdenum content of the materials. Again pitting resistance equivalent (PRE) (see Pitting corrosion) can be taken as criteria for assessing the resistance to crevice corro-sion.

Appendix B Corrosion resistance
Contact corrosionA corrosion type which may result from a combination of different materials.
Galvanic potential series are used to assess the risk of contact corrosion, e.g. in seawater. Metals which are close together on this graph are mutually compatible; the anodic metal corrodes increasingly in line with the distance between two metals.
Materials which can be encountered in both the active and passive state must also be taken into account. A CrNi alloy, for example, can be activated by mechani-cal damage to the surface, by deposits (diffusion of oxygen made more difficult)
or by corrosion products on the surface of the material. This may result in a potential difference between the active and passive surfaces of the metal, and in material ero-sion (corrosion) if an electrolyte is present.
DezincingA type of corrosion which occurs primarily in copper-zinc alloys with more than 20% zinc.
During the corrosion process the copper is separated from the brass, usually in the form of a spongy mass. The zinc either remains in solution or is separated in the form of basic salts above the point of cor-rosion. The dezincing can be either of the surface type or locally restricted, and can also be found deeper inside.
Conditions which encourage this type of corrosion include thick coatings from cor-rosion products, lime deposits from the water or other deposits of foreign bodies on the metal surface. Water with high chlo-ride content at elevated temperature in conjunction with low flow velocities further the occurrence of dezincing.

Resistance tableThe table below provides a summery of the resistance to different media for metal materials most commonly used for flex-ible elements.
The table has been drawn up on the basis of relevant sources in accordance with the state of the art; it makes jet no claims to completeness.
The main function of the table is to pro-vide the user with an indication of which materials are suitable or of restricted suit-ability for the projected application, and which can be rejected right from the start.
The data constitutes recommendations only, for which no liability can be accepted.
The exact composition of the working medium, varying operating states and other boundary operating conditions must be taken into consideration when choos-ing the material.
