Service & Maintenance | Pre-Sale & After-Sale Service

One of the core objectives and tasks of our company is the sustainable and future-oriented development of materials and sealing systems that allow the implementation of and compliance with ever increasing requirements for the reduc-tion of harmful emissions, and to make the findings available as "Best Available Techniques" [BAT]. To pursue these objec tives, we have a well manged in-house research and develop ment department that is equipped with state-of-the-art techno logies. Our R&D and quality management is forward-looking and target-oriented. Our inventions, patents, and property rights, as well as internationally recognised certificates and approvals document the seriousness with which we approach and foster innovation.

We implement the best practice recommendations of our industry, and base our high quality standards on ongoing self-assessments and performance comparisons. Close cooperation with universities and technical colleges, inde-pendent research institutes, national committees and commissions are a given. We maintain relationships with the Center of Sealing Technology [CST] at the University of

Applied Science in Münster, the DIN standards committee NARD [Normenausschuss Rohrleitungen und Dampfkesselanlagen], the German research network AiF, and the TÜV.

BEST AVAILABLE TECHNIQUES [BAT] In the European Community, emission limit values are defined in the Industrial Emissions Directive [IED] 2010/75/EU, which also outlines the implementation of BAT in the national legislation of the EU member states. It states that environ-mentally relevant industrial plants in particular must be BAT-approved. Best Available Technology is a European clause that is increasingly gaining importance internationally. The core idea of BAT is to design "activities and operational procedures" in such a way as to prevent - or where that is not possible - reduce harmful emissions and negative effects on the environment.

CALCULATION OF GASKET PARAMETERS.

Support | Service & Maintenance

Gasket parameters are an important component in the calcula-tion of flange connections. The European standard DIN EN 13555 specifies the parameters for seal designs and gasket materials in accordance with DIN EN 1591-1. It furthermore details test procedures for the calculation of the relevant numerical values, which are determined by test institutes, or tested and verified by manufacturers in in-house random sample tests.

The parameters for many of the most common gasket materi-als [in accordance with DIN EN 13555] can now be requested from the database of the Center of Sealing Technologies [CST], which is maintained by the University of Applied Science in Mün-ster. Plant engineers use these parameters for their calculation models, which in turn help to fulfil the tightness requirements in accordance with DIN EN 1591-1 "Flanges and their joints - Design rules for gasketed circular flange connections, bolts and gaskets". Manufacturers use the comparison analyses for their own quality assurance procedures and for the interpretation of manu facturer or material-specific differences and characteristics.

IN-HOUSE TEST BENCHESOur own test benches by Amtec are considered the standard in measurement technology and are used worldwide. The gasket test benches can be used for compression, pressure status, creep, and relaxation tests, as well as for traditional leakage tests. The test bench also permits component tests in actual flange connections to verify the quality of the seal according to the test criteria of TA Luft [Clean Air Act].

The test verifies the sealing behaviour as specified in VDI 2440/ 2200 after temperature exposure. Our valve test bench allows us to verify the quality of the seals [stuffing box packing and housing seal] in mounted valves. The seal quality is tested by way of calculating the leakage rate under controlled operating condi-tions in accordance with the standards TA Luft and ISO 15848-1. Custom test procedures can be defined, or standard test pro-cedures applied [in accordance with ISO 15848-1, VDI 2440, or API 622]. The test focuses on the detection of friction forces in the spindle movement, and the determination of the sealing characteristics of the seal components. With our test module for stuffing box packings, we emphasise the calculation of para-meters.

CALCULATIONSThe requirements for sealing connections and the restrtiction of harmful emissions have been increasing steadily over the past years. National and European regulatory requirements, like the Pressure Equipment Directive [PED], demand a significantly more detailed depth of verification due to stricter environ-mental requirements [e.g. TA Luft, VDI 2290]. The test analy-

ses the entire flange connection system — flange, bolt, gasket — for which an "appropriate design" and the "use of appro-priate gasket parameters" is required. The European standard DIN EN 1591-1 specifies a calculation method for flange con-nections with round flanges, bolts and gaskets, which has the following purpose:• Ensuring the robustness of the design, and

• Verifying the tightness of the seal

For this purpose, gasket parameters are applied, which are based on definitions and test procedures in accordance with DIN EN 13555. The aim of the calculations using the algorithm of DIN EN 1591-1 is therefore the verification of stability for all tested load cases, knowledge of the maximum capacity for utili-sation in order to limit the stress on individual components, and proof of seal tightness allowing for sufficient surface pressure of the gasket in operation.

The calculation specifies the required tightening torque [torque force for installation], without which no reliable installation and therefore no safe system operation can be achieved; this value is mandatory and independent of whether the gasket has a standard or custom design.

We offer our customers analytical procedures in accordance with DIN EN 1591-1 for the calculation of flange connections and pipe classes. In collaboration with our technology partners, we furthermore offer calculations in accordance with KTA 3211.2, as well as detailed finite element calculations.

TAR-SERVICE.

Service & Maintenance | TAR-Service

Gaskets are an essential component in chemical, petro-chemical, and other industrial systems. They ensure smooth and efficient operations, as well as stable, and reliable production. High quality sealing systems minimise harmful emissions, increase operational safety, and therefore reduce overall operating costs. The use of sealing systems requires high precision and expert knowledge, fast response times, and correct on-site installation procedures. Our service con-cept for turnaround, shutdown, and revision offers operators tried and tested solutions for system availability and instal-lation procedures, as well as excellent support before and during the TAR project. These services are available as indi-viduals modules and in combination.

03 ENGINEERING ESSENTIALS.

FUNDAMENTALS OF SEALING- & VALVE TECHNOLOGY

NORMS | STANDARDS | REGULATIONS

APPROVALS | PROFILES | PARAMETERS

2020

The sealing system in bolted connections is only part of an equa-tion with several components. A holistic view of all aspects is needed to provide a functional statement regarding the correct design of a flange connection and the low immission operation of a plant. Based on the findings of numerous scientific studies and projects, the theoretical controllability of emission-intensive flange connections was thoroughly researched and in part re -defined during the past years. New findings were implemented in collaboration with manufacturers, and new materials and gasket designs were established. The current state of technology is such that high operational safety and system availability can be ensured.

VDI 2290 [Key indicators for emission reduction in flanged con-nections] is seen as the standard for assessing technical tightness for those liquid and gaseous media, for which emission- limiting requirements [sealing classes] are specified in accor dance with the TA Luft [Clean Air Act]. The standard applies only for metallic connections in pipelines, on apparatuses and valves of all industry sectors - specifically in the chemical and petrochemical industries - to a max. operating temperature of 400 °C.

Furthermore, the standard contains explanations regarding the correct selection of gasket parameters, and all additional required information for the calculation of flange connections. Important to note is that each flange connection or pipe class must be viewed individually for each application, as the standard provides additional requirements in terms of tightness, docu-mentation, and quality assurance verification. The selection of a technically tight flange connection should therefore be based on at least the following five steps:

1 Operating conditions

2 Legal requirements & regulations

3 Structural design

4 Calculation

5 Installation

OPERATING CONDITIONSEvery process, each procedure and application poses specific requirements for the installed flange connections. The key influ-encing variables are:

• Pressure

• Temperature

• Medium

• Plant operating mode

The analysis and assessment of these parameters allows an initial presumption regarding the selection of an appropriate sealing material or -system.

LEGAL REQUIREMENTS & REGULATIONSOperators are faced with many legal requirements, which directly impact their selection of sealing systems. The most common requirements include:

• TA Luft 2002 [Clean Air Act]

• Blow-out safety

• Fire safe test

• BAM test for reactivity with oxygen

• FDA approval

Gaskets must be tested in standard verification procedures by independent institutes and must be provided with relevant documentation and confirmation by the manufacturer to gain approval from government authorities. The structural design process can begin, once the sealing material and sealing system has been proven to comply with operational and legal require-ments for the specific application.

STRUCTURAL DESIGNDuring the construction phase, the appropriate flange and bolt materials, as well as the combination of flange geometries are selected, dimensioned, and documented in line with the rele-vant operating conditions and legal requirements. As a last step, calculations of:

• a component strength verification or

• a component strength and tightness verification

for the entire system [flange-bolt-gasket] of the flange con-nection design is to be provided, and documented in accordance with the valid standard.

CALCULATIONThere are various methods for providing the required verification of component strength and tightness.

The default method chosen today is often stilll the mere strength verification in accordance with AD 2000 regulation [leaflets B7 und B8]. The result of the calculations provides the plant engi-neer with a verification that the flange connection he selected is designed correctly, and that plant safety can be sufficiently guaranteed. According to the current state of technology, a com-ponent strength verification will not suffice if the plant is liable to TA Luft, or if the plant is operating with critical media, e.g. toxic or carcinogenic materials. Where that is the case, the verification will have to be provided in accordance with the calculation standard DIN EN 1591-1. This standard outlines the verification of component strength and tightness. In case of TA Luft appli-cations, the verification of compliance with a specific leakage rate is mandatory and specified in VDI 2290 [Emission Control: Sea ling constants for flange connections]; the specified leakage

rate ≤ 0,01 mg•s–1•m–1 must be verified for existing operating conditions. The same calculation is recommended for all other critical use cases. As a result, the plant operator receives a statement regarding the technical tightness of the flange connection in addition to the required component strength verification.

An important foundation for the DIN EN 1591-1-compliant calculation is that sealing parameters in accordance with the testing standard DIN EN 13555 are used. That is why manu facturers are bound to determine the relevant seal parameters in tests. Plant operators furthermore demand a verification of the values determined by the manufacturers, and their publication in the CST [Center of Sealing Techno-logies] database maintained by the University of Applied Sciences in Münster.

INSTALLATIONIn the past, the importance of the correct installation of a technically tight flange connection was often underestimated. Since VDI 2290 became a stan dard, the implemen tation of a technically correct installation has become as mandatory as the above mentioned verification calculation. This requirement was further specified with the introduction of DIN EN 1591-4.

The standard describes the basic know ledge, qualifications, and capabilities required for installation personnel tasked with the installation of bolted connections in pressurised sys-tems for critical use cases. In addition, the German chemical industry has created a guideline document for the implemen-tation of a controlled installation, which is avail able via VCI [Verband der Chemischen Industrie]. In the end, a qualified installation can ensure that a pre-defined leakage class can be warranted and maintained during operation.

Engineering Essentials | Fundamentals

2222

Static sealing systems, as used in flange connections and valves, must comply with regulatory requirements in terms of plant safety, explosion and fire safety, work safety, exposition, health safety, and environmental protection, i.e. emissions into the ground, air, and water. Many of these requirements are in part described in various laws, directives, technical requirements, and standards. As a result, different technical solutions or pro-cedures may apply for the implementation of these technical guidelines, and therefore differences in the definition of the state of technology.

Requirements are commonly phrased in terms of quality - tech - nically tight or permanently technically tight, which often makes the selection of the material or sealing system a difficult task.

A number of different decision-making and processing steps become apparent when we look at the development process of a technical system. These include:

• Procedure and process development in laboratory and practical environments, as well as scale-ups to industrial scope

• Feasibility study; decision regarding project start

• Concept phase, as well as cost and time estimates for the investment project

• Design planning or basic engineering

• Approval planning and procedure

• Implementation planning or detail engineering construction/ commissioning of the system and handover to the operator

Pipe components and pipe classes are specified as early as during the basic engineering phase, and are therefore binding specifi-cations for detail planning. Components like pipes, form pieces, flanges, and seals that are made of the same material and one spe-cific nominal pressure class, but are valid for different diameters, are all grouped together in one pipe class.

Pipes transport fluid media [gases, liquids, or other free flowing or pumped solids]; Carrying of such media in technical systems is subject to specific physical conditions [pressure, temperature, and aggregate state], as well as specific chemical material pro-perties: Reactivity with other materials, e.g. water, acid, base; corrosion resistance, explosiveness, solubility, etc.

The material requirements and structures of the components of a pipe are derived from the properties of the medium to be transported and the process conditions. They have to withstand stresses from a combination of pressure, temperature, and corrosion stress, while keeping work standards in mind. In cases of hazardous media, a verification and certification of the pipe class may be required.

The pipe class specifies the max. values of permissible pressure and temperature under which the pipe can be operated safely, therefore defining the area of application and interdependencies. The application scope is limited by the strength of the weakest

construction component. The selection of pipes, flanges, and bolts is rela tively straight forward as they are defined in the technical standard. The selection of the sealing material and system, on the other hand, is generally much more complex.

Practical applications have shown that there are a multitude of optional sealing systems available for equal operating para-meters.

The creation of standard pipe classes is based for the most part on DIN EN 13480, the pipe classes are publicly available, and are described in PAS 1057 [Publicly Available Specification]. They

• comply with the requirements of the Pressure Equipment Directive [DGRL]

• take into account the many years of relevant operating experience of the companies/operators involved

• standardise pipeline components

• simplify the composition of pipe classes by way of component catalogues

• create standardised pipe classes for pipelines in process systems

PAS 1057 describes the seals to be used, but the selection of appropriate sealing systems still remains problematic in practical terms. The differences by manufacturer can be very distinctive, even if the system is part of the same sealing type, which is do cumented in the leakage rate verification in accordance with DIN EN 1591-1.

DIN EN 1514 is the normative basis for static, removable seals for flanges with PN designation, and DIN EN 12560 is the basis for flanges with class designation.

Gaskets made of soft material are generally low profile seals for even surfaces, which are compressed using external forces. They are not pressure-activated, and therefore do not auto-matically adapt to the sealing pressure. The gasket/sealing system types can be sub-divided into three main groups:

1. Non-metallic gaskets* 2. Semi-metallic gaskets 3. Metallic gaskets

[*]see also DIN 28091 "Technical delivery conditions for gasket sheets"

Experience has shown that despite specific parameters, the designe of a flange connection is much more complex, also because the VDI 2440 type verification does not allow a reason able assumption of how the sealing system will operate in practice and under actual operating conditions. The measured leakage rate is often erroneously used as sole benchmark for the quality assessment of a gasket or sealing system.

The construction design verification, however, is conducted under laboratory and standardised conditions, and therefore relates very little to the actual working conditions faced by the system operator. There is no guarantee that these gaskets - even if TA Luft compliant - are suitable for actual working conditions and fulfill the requirements for their intended use.

Additional regulations, such as TRBS 2152 Part 2 [Technical rules for operational safety/hazardous materials; prevention or limitation of hazardous, explosive atmosphere] contain statements regarding the long-term technical tightness of flange connections.

According to these rules, the following non-permanent con-nec tions are considered technically tight:

• Flanges with weld ring gaskets

• Flanges with tongue/groove gaskets

• Flanges with male/female gaskets

• Flanges with V-grooves and V-groove gaskets

• Flanges with smooth raised-faces and special gaskets. Such as non-metallic gaskets up to 25 bar, gaskets with metal interior eyelet or metal-jacketed gaskets, if a mathe- matical verification demonstrates sufficient safety against the stress limit

However, a precise specification of which gasket or sealing system should be used is missing.

ASME BOILER AND PRESSURE VESSEL CODE The ASME Boiler and Pressure Vessel Code of the American Soci-ety for Mechanical Engineers [ASME] regulates all requirements for pressurised components in terms of material, calculation, manufacturing, verification, inspection, testing, certification, and overpressure protection. ASME is comparable with the German engineers [VDI] and has over 120,000 members worldwide.

The ASME code itself is sub-divided as follows:

• Sections For the various types of vessels [steam boilers, heating boilers pressure vessels, etc.], manufacturing steps [welding, NDT] and materials

• Code Cases Special approvals for designs or materials, which are not allowed or listed in the document

• Interpretations Explanations of the rule set by ASME

• Reference Standards e.g. ASME B16.5 Flanges, ASME B16.9 Valves

• Other Regulations e.g. for pipelines: B31.3 Process Piping, B31.1 Power Piping, etc.

The first edition of ASME Code Section I for steam boilers was published in 1914. The ASME Code has been regularly extended and updated since then. Since 2011, a new edition is published every two years. The biennial edition has replaced the pre-2010 practise of new editions every three years plus annual supple-ments. The exception are the "Reference Codes" like ASME B16.5 for flanges or pipeline specifications, which are updated irregularly.

New editions of the ASME Codes are released biennially on July 1. Mandatroy compliance with the new code starts on January 1 of the subsequent year.

For new orders it is imparative that the latest edition of the ASME code, valid at the time when the order was first received, is used.

The ASME Code is published in English, and there are various translations available. In German, the ASME Code is published by the Fachverband Anlagenbau: Energie, Umwelt, Prozessindustrie. The German translation is very good, but not officially approved by the American Society for Mechanical Engineers, and therefore meant only as reference. An Official ASME edition must be used for compliance with the ASME Code requirements.

BAM oxygen The Federal Institute for Materials Research and Testing [BAM] tests gaskets for flange connections on oxygen lines and valves. BAM leaflet M 034-1 contains a list of tested non-metallic materials [DGUV Information 213-075, previously BGI 617-1], which were tested and approved for use in system parts for oxygen. BAM leaflet M 034-2 contains a list of tested, non-metallic materials for valves, tubes, and system components [DGUV Information 213-076, previously BGI 617-2].

BAM EO/PO The Federal Institute for Materials Research and Testing [BAM] tests gaskets for flange connections in ethylene and propylenoxide applications.

EC 1935/2004 Regulation by the European Parliament regarding materials and items intended for coming into direct contact with foods and to rescind directives 80/590/EEC and 89/109/EEC.

FDA Fulfills food law requirements with regards to materials in direct contact with food set out by the U.S. Food and Drug Admini- stration [FDA].

Fire Safe Test The "Fire Safe Test for Valves" verifies, whether shut-off devices function and seal reliably in case of advanced or initial fires. The tests are defined in various industry standards for valves, e.g. API 607, BS 6755-2, EN ISO 10497. The requirements of this standard are tightness of the performance components for a time span representative for the time needed to extinguish most fires. From this results: „Maintaining seal properties under temperature influences of 650 °C during 30 minutes.“

AFM 34 CO ME®. Blow-out resistant gasket with optimised inner eyelet.

DESCRIPTION

The basis for the gasket is the established gasket material AFM 34® by REINZ. This design is equipped with a novel innova-tive coating [CO] to optimise surface fit and is manufactured in a combination of a metallic surround [ME] made from 0.10 mm thick stainless steel 1.4571 and a special flanging process. As a result the blow-out resistant non-metallic gasket made from AFM 34 CO ME® is characterised with a significantly improved micro fit and leakage rate, offers maximum gas tightness even at low surface pressure and complies therefore to even the highest, legal requirements. Guidelines such as the VDI 2290 require for TA Luft relevant media stricter leakage rates which cannot be achieved with standard hemmed gaskets. Therefore, our AFM 34 CO ME® is the ideal gasket to adhere to the emission limit values in the system "flange-gasket-bolt" also in consi-deration of the tightness class as per VDI 2290 based on TA Luft.

PROPERTIES

• Use of the established gasket material AFM 34®

• Highest gas tightness even at low surface pressure

• Ideal conditions when calculating flange connections as per DIN EN 1591-1 to adhere to tightness class as per VDI 2290

• Low force absorption of the inner eyelet [optimised surface pressure distribution]

• Blow-out resistant even in the event of extreme pressure surges

• High chemical resistance [resistance chart available upon request]

• Improved micro adjustment and leakage rates

• Temperature range from -50 °C up to approx. 150 °C [200 °C possible upon prior consultation]

• Complies with TA Luft 2002 [VDI 2440/2200] leakage requirements

• Scratch resistant, strudy surface, easy to handle

APPLICATIONS

• Non-metallic gaskets for flanges

• Used in the chemical and petrochemical sector

• Used in the natural gas sector to secure higher liquid and gas pressures

• Used if there are increased requirements for blow-out resistance [technical tightness] as per e.g. TRBS 2152 T.2

DESCRIPTIONIDT-graphite sheets and seals consist of high quality SIGRAFLEX® material. For the production of SIGRAFLEX® products, flaked natural graphite is used which has a good crystalline structure. The high purity of SIGRAFLEX® is determined by the raw materials and ensured by the quality of mechanical, chemical and thermal cleaning processes. Graphite sheets are manufactured without reinforcement, metal- reinforced and/or waterproofing whilst the metal reinforcement can be done with sheet reinforcement or smooth stainless steel foils. The graphite sheets have higher strength, gas tightness, scratch resistance and non-adhering surfaces thanks to the special waterproofing.

• Low permeability towards gases and liquids

• Flexible, soft, good adaptability

• Very good media resistance, specifically against corrosive substances and chemicals [resistance chart available upon request]

• Does not present a health risk and is environmentally friendly

• Temperature range from -200 °C to approx. 550 °C [upward to 450 °C please consult the manufacturer]; special construction [FD33] up to 600 °C

• Ageing resistant, no embrittlement, since no binders or elastomer matrix

• Long-term stable compression and recovery characteristics

• Good temperature change resistance and constant diffusion rate


• No cold and warm flow until maximum permissible surface pressure

• High pressure stability

OPTIMISED TECHNOLOGY CLEAN ENVIRONMENT

IDT only processes graphite qualities by SGL Group. SIGRAFLEX® UNIVERSAL and SIGRAFLEX® HOCHDRUCK are among the materials which have been established in the market for years. They are considered state-of-the-art and have proven their value in all industrial applications.

With the commencement of the increased requirements of TA Luft in 2002, it had become necessary to develop new production technologies and product variations to comply with the required emission reductions. The product ranges SIGRAFLEX® PRO, SIGRAFLEX® SELECT and SIGRAFLEX® MF were introduced to meet these requirements and were - mostly with eyelet design - standardised by plant operators.

Based on this environmental and safety relevant background as well as in harmony with applicable environmental protection regulations, various IDT-sealing systems were optimised with

regards to their design and production, so that they complied both with the TA Luft requirements as well as the calculatory strength and tightness certificate following DIN EN 1591-1 which has been required since the inception of VDI 2290 in 2012.

The optimised sealing systems are labelled with the IDT envi-ronmental label for Low Emission [LE]. Subsequent calculations of pipe classes following DIN EN 1591-1 were carried out on the basis of the VCI-guideline for the assembly of flange connec-tions in process plants and have shown that the leakage rate of 10^-2 mg/[s*m] could be adhered to with all LE versions; in parts even with a bolt quality of 5.6.

In addition to increased leakage requirements and due to higher process temperatures in plants, it also has become necessary to produce the graphite with an increased oxi-dation protection and to equip it with an oxidation inhibitor which is applied directly to the structure of the graphite foil. SIGRAFLEX® APX-foil sets the standard for these applications and has a significantly improved temperature resistance in comparison to standard graphite qualities.

DESCRIPTION

IDT-PTFE-sheets and gaskets are made from high quality 3M™ Dyneon™ TFM™. The basic characteristics of PTFE [polytetra-fluoroethylene] are based on the special molecular structure of the fluorine and carbon atoms; both chains have an extremely strong bond. The carbon network is hermetically sealed by the fluorine atoms which makes a chemical attack extremely hard and the PTFE therefore becomes resistant to chemicals and solid. The pharmaceutical-chemical industry requires low per-meation for sealing applications, high chemical resistance, solid mechanical resilience and easier processability. Only few mate-rials, mostly on fluoropolymer basis, combine these advantages. TFM™, a PTFE of the second generation, has proven itself. TFM™ distinguishes itself from classic PTFE by the additionally applied modifier. The particles melt more easily into a dense, low pore poly mer structure due to the achieved, more homogeneous crystalline structure; as a result the tightness is significantly improved. A further disadvantage of classic first generation PTFE is that it flows under load [cold flow] and resulting in a loss of sur-face pressure in clamped condition. This negative characteristic has been significantly improved with the development and gasket technology application of TFM™ and the cold flow behaviour has been optimised. An additional modification can be achieved in a finishing process by mixing in filler or aggregates. During recent years, the use of the modified compound TFM™ 4105 with 25% glass fiber content has stood the test in the gasket technology practice. Semi-finished products and sheets as the source material for non-metallic gaskets are produced in a press-sinter process.

PROPERTIES

• Very good media resistance with the exception of liquid alkali metals and some flourine compounds

• Fillers in compounds affect the chemical resistance

• Electrical conductivity for TFM™ 6221 compound with conductive pigment; also FDA-conform

• Temperature resistant from -200 °C to 260 °C [depending on pressure and load]

• PTFE is physiologically harmless for continuous operation temperatures up to 260 °C as per BG no. 21

• FDA-conform and complies with regulations in Europe and Asia for food use

• TFM™ allows for immediate welding, which is safe and easy using a special technique


• Good non-stick characteristics

• UV- and ageing resistant, no embrittlement


• Anti-adhesive surface

• Excellent [di]electric properties

• Fire class: is not flammable as per UL94

APPLICATIONS


• Broad range of applications primarily in the chemical and petro - chemical sector

• Use in the food sector and pharmaceutical production

• Non-metallic layers for corrugated metal and Kammprofile serrated gaskets as well as insert for spiral wound gaskets


• Use in oxygen applications depends on the compound [BAM-test report]


• Foils and sheets

Sealing system made from modified, cold flow reduced Dyneon™ TFM™ 1600 without fillers. Characterised by a dense, homogeneous, almost non-porous polymer structure. Maximum chemical resistance due to the absence of fillers.

Sealing system made from modified, cold flow reduced Dyneon™ TFM™ 1600 with inner and outer eyelet was developed specifically for tongue and groove areas, male and female flanges and similar applications. The double eyelets create a chambering effect. Material extrusions into the sealing gap and flowing of the gasket are prevented by eyelets.

Sealing system made from modified, cold flow reduced Dyneon™ TFM™ 4105 with a glass fiber content of 25%. The modification and the glass fiber content cause a reduced cold flow and an increased pressure stability in comparison to standard PTFE. The chemical resistance is only slightly impacted by the glass fiber content.

DESCRIPTION

UNIFLUOR® gasket sheets are manufactured in a special production process which causes a very strong, biaxial orientation of the PTFE molecules. This results in a significant reduction of the negative creep and setting behaviour which is typical for classic PTFE. The sheets are also homogeneously filled with specific sub-stances in addition to the optimisation of sealing technological properties and depending on the application area. Primarily, three types of fillers are used in gasket sheets as standard. They can be distinguished from the outside by the different colouring.

Standard fillers are:

• Glass microspheres, sheet colour code: blue Application: Glass lined pipelines, compressible

• Silicate/quartz, sheet colour code: brown Application: Steel/stainless steel pipelines and containers, normal density

• Barium sulphate, sheet colour code: white Application: Steel/stainless steel pipelines esp. pharmaceutical and food applications, high density

PROPERTIES


• Fillers in compounds affect the chemical resistance

• Temperature resistant from -200 °C to 260 °C [depending on pressure and load]






• Very good non-stick characteristics


APPLICATIONS


• Broad range of applications primarily in the chemical and petrochemical sector

• Use in food sector and pharmaceutical production

• Suitable for the use in oxygen applications depending on filler

• Suitable for the use in EO-PO applications depending on filler

• Increased blow-out resistance for designs with inner eyelet


• Sheets

• Dimensions: 1500 x 1500 mm [standard format]

• Available thicknesses: 0.75 ;1.0; 1.5; 2.0; 3.0 mm

DESCRIPTION

Extruded PTFE foils are drawn multiple times in a special pro-cess and combined into a homogeneous gasket sheet for the production of UNIFLUOR® multidirectional oriented expanded PTFE sheets and gaskets. UNIFLUOR® ePTFE sheets achieve a very high strength in longitudinal and cross direction due to the multidirectional oriented fiber structure. The flow behaviour under load and temperature is significantly reduced in comparison to other PTFE gasket sheets. The soft materials adapts perfectly to uneven sealing surfaces and compensates even large gaps if the gasket thickness is chosen accordingly. UNIFLUOR® ePTFE provides sizeable, effective recovery. A sufficiently compressed in gasket once installed ensures a high tightness class even if the surface pressure is reduced during operation. UNIFLUOR® ePTFE gasket WS 7745 HB was deve loped for the use in stress-sensitive flange connections and consists of: UNIFLUOR® ePTFE gasket [low density] with inner eyelet, made from sintered, almost non-porous 3M™ Dyneon™ TFM™ WS 7110 [high density]. The inner eyelet increases the diffusion resistance and reduces a possible permeation significantly. The gasket is highly pre-compacted on the outside to ensure that the occurring stresses can be reduced as much as possible in order to reduce the pre defor mation forces. The sealing system is characterised by extremely low leakage rates, very low surface pressures and complies with the highest requirements in pro-cess purity.

PROPERTIES

• 100 % pure, virgin PTFE, without fillers, no colouring or stamping ink

• High longitudinal and cross strength; extremely low cold flow and a very high pressure stability

• Low setting behaviour, only minimal width increase under load









• Prime elasticity

APPLICATIONS




• Suitable for the use in oxygen applications

• Sealing of stress-sensitive materials such as enamel, FRP, glass, ceramic

• Suitable as sheet material for punching and on-demand cutting [all shapes] for repairs and revisions



• Sheets

• Dimensions: 1500 x 1500 mm [standard format]

• Available thicknesses: 0.5 to 6.0 mm [9 mm upon request]

FEP.

DESCRIPTION

FEP [Fluorinated ethylene-propylene] is a thermoplastic material with properties similar to PTFE. O-rings which are seamlessly coated with FEP have an elastic core made from FPM or VMQ and are used if very high thermal or chem-ical loads are present. The high chemical resistance of the coating protects the core against damage by the potentially aggressive medium. FEP coated O-rings are used - similar to PTFE-rings - where the chemical resistance of the normal elastomer O-ring is no longer sufficient, but where a certain elasticity is needed. The elasticity is ensured by the inner ring and the chemical resis-tance is achieved by the seamless FEP coating.

PROPERTIES

• Very good chemical resistance against most liquids and chemicals

• Temperature range from approx. –60 °C to 200 °C [depending on inner ring material]

• No contamination of food, pharmaceutical or medical products

• Physiologically harmless, can be sterilised

• Sufficient elastic behaviour

• FEP O-rings can be replaced with standard O-ring seals without limitation

• No changes to the groove dimensions are necessary

• The O-rings are less flexible than elastomer O-rings due to the FEP coating. They can only be stretched minimally and have a lower elasticity or a higher permanent deformation

APPLICATIONS

FEP coated O-rings are perfectly suited for the chemical and petrochemical sector, medical technology, food sector, water and waste water technology and similar industrial appli-cations. A typical application for FEP coated O-rings is the sealing of valve stems and as a secondary sealing element for slow switching and rotary movements.

DESCRIPTION

Rubber-steel gaskets [G-ST] are used in bolted connections in which only low bolting forces can be realised. The elastomer properties allow on the one hand a very good adjustability to the sealing surface, on the other hand low leakage rates are achieved due to the homogeneous structure. The use of a centrally fitted, corrosion protected and vulcanised steel insert increases the blow-out resistance and stability. Therefore, the gasket is easy to handle even at large nominal widths. Extreme adhesion between steel insert and the rubber jacketing is ensured due to the vul-canisation. No moving, removal or even blow-out is possible even at the highest stress loads. The gaskets have a wide range of applications depending on the relevant elastomer and are suit-able for water, water vapour, gas, air, acids, bases, hydrocarbons whilst application temperatures of up to 200 °C are possible. Rubber-steel gaskets [G-ST] are manufactured in various shapes according to the application area and the specified flange material [e.g. steel, FRP] and can be used in off- load and main load applications.

• GS01: G-ST flange gaskets, universal application [main load]

• GS10: G-ST-P/S, universal application, ideal for flange connections made from steel-plastic and cast-plastic [main load]

• GS20: G-ST-P/OE, flexible design gasket with visible stainless steel insert [main load]

• GS30: G-ST-P/K, ideal for flange connections made from pairs of plastic compounds [main load]

• GS50: G-ST-P/KN, universal application, ideal for partially covered flanges and extreme stresses [off load]

The combination of G-ST-base body and O-Ring at the inner diameter combines the advantages of the individual elements. The sealing ring located at the force bypass clings perfectly to the sealing surface even at low surface pressures. Uneven areas and score marks, even slight adjustment tolerances are com-pensated. An hitherto impossible operational safety is ensured in addition to material-efficient assembly at only low necessary tightening torques. Rubber-steel gaskets comply with TA Luft when adhering to the maximum installation surface pressure.

PROPERTIES

• High gas and liquid tightness even at low surface pressures

• Compensation for surface defects, very good elasticity and good recovery behaviour

• Flange and bolts can be of a weaker design

• Lifespan of plastic flange connections is significantly higher [consideration of the creep test behaviour]

• Good compensation behaviour in the event of angle deviations


• Blow-out resistant following TRBS 2152 part 2

• Very good handling during transport, installation and dismantling, mechanically stable

• Individual marking of each gasket at the outer edge

• Grooves for the sealing ring or offset-grooves on the flange are not neccessary [G-ST-P design]

APPLICATIONS

• Gaskets for pipeline flanges, device and container flanges

• Gas/water pipeline construction

• Plastic pipelines

• Rubberised flanges

• Connections sensitive to stress [e.g. glass flanges]

• Vacuum

Rubber-Steel gasket [G-ST]

Rubber-Steel gasket [G-ST-P/S]

The gasket consists of a lens-shaped rubber body and an interior steel ring. The rubber jacketing is vulcanised firmly to the steel insert which creates a sturdy compound which can withstand even high stresses. The steel insert increases the blow-out resistance and stability of the sealing system. The lens shape causes a partial increase in surface pressure.


The lens-shaped base body is also equipped with an O-ring as static sealing element. Surface defects and angle deviations in the flange are compensated more easily. The rubber jacketing is vulcanised firmly to the steel insert which creates a sturdy compound which can withstand even high stresses. The steel insert increases the blow-out resistance and stability of the sealing system.

DESCRIPTION

The pharmaceutical-chemical industry requires low permeation for sealing applications, high chemical resistance, sturdy mechanical resilience and easier processability. TFM™, a PTFE of the second generation, has proven itself. The particles melt more easily into a dense, low pore polymer structure due to the more homo-geneous crystalline structure; as a result the tightness is significantly improved. High quality 3M™ Dyneon™ TFM™ is used for the envelope gaskets.

PTFE envelope gaskets combine the positive characteristics of TFM™-material with the mechanical behaviour of the relevant inserts and have a very high chemical resistance. The positive characteristics are completed with a sturdy diffusion barrier at the inner diameter of the gasket and are optimised across the entire gasket diameter with regards to diffusion. This combination gasket is therefore used for a wide range of applications.

Optimised corrugated ring geometryThe IDT-elastic gasket with metallic corrugated ring insert and diffusion barrier [PW-I] was developed for steel and stainless steel flange connections as well as defined as a standard in the chemical industry. This gasket system can be used at 40 bar and 200 °C simultaneously - which cannot be achieved with clas-sic PTFE gaskets - thanks to the optimised coordination of the mechanical characteristics of the stainless steel corrugated ring with the TFM™-envelope. The corrugated ring insert is also used to increase the bursting and blow-out resistance. The geometric design of the corrugated ring was chosen in such a way that it prevents cutting through the enclosing TFM™-envelope [cross- sectional flat area] and that it has an optimised characteristics profile due to the chosen corrugated partitions of 3.0 mm.

Other TFM™-envelope combinations with inserts have proven themselves in areas which are sensitive to stress, especially for glass lined flange connections. The conditions which are found on the sealing surfaces specifically in enamel applications, such as aggressive media, low surface pressure, sensitive flange sur-faces, waviness and warping on the flange sealing surfaces, place high demands on the sealing system.

Non-metallic insert | SIGRAFLEX® EMAIL [WS 3825]The graphite sheet SIGRAFLEX® EMAIL was developed specifically for use in PTFE-coated non-metallic gaskets, which as a non- metallic insert ensures an ideal interplay of the already out-standing characteristics of the individual components. There is a significant improvement of the sealing technological pro-perties of the PTFE-envelope gaskets thanks to the good recovery property of the graphite, the stainless steel foil insert close to the surface and the combination of the individual layers without adhe-sives. SIGRAFLEX® EMAIL is a multi-layer sealing sheet made from flexible graphite foil which is reinforced with two 0.05 mm thick stainless foils.

SIGRAFLEX® EMAIL is made in sheet thicknesses of 2.0 mm and 3.0 mm and consists of two 0.5 mm thick outer and one 1.0 mm or 2.0 mm thick inner layers of flexible graphite with the density of 1.1 g/cm³. The compound is made without adhesive using a special process and corresponds therefore to the highest require-ments with regards to strength even at high temperatures.

TFM™-envelope gasket for food and pharma applicationsQuality systems, which regulate the manufacture of medicines and pharmaceutical substances were successfully introduced in the EU. The current good manu facturing practice [GMP] gua-rantees the safety of pharma ceutical raw materials and pro-ducts but also applies to cosmetics, food and feed and also includes the relevant quality requirements. IDT has developed an envelope gasket for these applications in consideration of GMP. This sealing system combines the positive character-istics of the TFM™-material as an envelope with those of the non- metallic insert made from the biaxial-oriented UNIFLUOR® [WS 7550]. All materials in this combination gasket are FDA- conform. Possible leaching of filler or colour pigments from the PTFE insert are safely prevented by the TFM™-coating. The sealing system convinces with a high diffusion tightness whilst featuring at the same time an ideal compensation behaviour which is achieved thanks to the low density of the non-metallic insert. The blow-out resistance is increased for designs with additional corrugated ring insert.

Envelope gaskets for electrostatic discharge Envelope gaskets can be of a dissipative/conductive design for applications for which a static discharge is necessary and required. For this purpose, it is possible to realise the discharge using an electrically conductive PTFE-envelope made from Dyneon™ TFM™ 6221 WS 7221 and/or using an grounding tab/ grounding wire which is fitted to the outer diameter of the corrugated ring. The discharge of the electrical load is ensured via glass lined pipes, metal reinforcement and fan-type lock washers. The retaining brackets can also be fitted to the corru-gated ring as assembly and centring aids.

Grounding and equipotential bonding in pipes with insulating gasketsThe grounding of a plant can be obstructed by insulating com-ponents such as gaskets or insulating operating materials like greases. The remaining conductive components have to be connected to each other and grounded when using insulating materials such as spacers made from plastic with high resistance. Alternatively, it is possible to ground every plant part individually. In this environment it is particularly important to consider parts which are not visible from the outside, such as: Ball valves with insulating gaskets or also metal inserts in gaskets.

It depends on the specific conditions if equipotential bonding is necessary for pipelines and gaskets:

• Insulating coating on the inside • Insulating coating on the outside • Gasket conductive or insulating

Conductive or insulating gaskets require more grounding efforts depending on the situation.

Requirements in equipotential bonding and grounding of conductive objects: Normally: Grounding is necessary, if capacity > 10 pF • Resistance < 1 MΩ at deep measuring voltage [e.g.10 V] In special cases: Grounding is also necessary

Independent from capacity: • if close to strong charge generating processes • if in touch with product flow in the equipment • if capacity > 3 pF and in zone 0 or 1 of materials in explosive group IIC

Resistance < 100 MΩ is enough, if: • Charge rate < 1μA and • Capacity < 100 pF

Industrial Safety and Health RegulationsThe technical regulations on industrial safety and health reflect the regulations on the state of the art, occupational medicine and hygiene and other workplace related findings for the provision and use of equipment and the operation of plants which require monitoring. The Chemistry Committee has created the following professional association regula-tion "Avoiding Risks of Ignition Resulting from Electrostatic Charges" [BGR 132]. They were adjusted to reflect current law, the developed state of the art and at the same time included in the TRBS 2153 during the development of uniform and coherent rules and procedures. The regulations correspond to the BGI 5127 "Avoiding Risks of Ignition Resulting from Elec-trostatic Charges" [Information leaflet T 033]. These technical rules apply to the evaluation and avoidance of risks of ignition resulting from electrostatic charges in explosive areas and for the selection and implementation of protective measures to avoid such risks.

DESCRIPTION

The IDT-corrugated metal gaskets consist of a corrugated stain-less steel carrier with a height of s = 1.5 mm and a graphite layer of 0.8 mm on both sides. Carrier profile, thickness and density of the layer are adjusted in such a way that a peak overlap of 0.1 to 0.2 mm is ensured in tensioned condition at standard com-pression and therefore only a very low diffusion cross-section is present. Furthermore, the non-metallic material is very highly compressed in these areas. A partition of 3 to 4 mm, a sheet thickness of 0.5 and a non- metallic layer thickness of 0.8 mm has proven to be the ideal design and is used as a standard by established plant opera-tors. The IDT-corrugated ring is manufactured across all nominal widths with a partition of 3 mm. If the corrugated ring is partitioned too much, then it loses in strength and has the effect that the proper function could not be achieved or could not be achieved fully and that that the mechanical characteristics and leakage related parameters are influenced negatively. The gasket has already a very good tightness at low surface pressures and is suitable for use in existing systems due to its good mechanical characteristics. The gasket can be manufactured in various shapes such as circular, oval, long oval and frame. Transport and handling limit the maximum dimensions [approx. 5000 mm]. Cross pieces [at least 8 mm wide], retaining brackets and bolt holes can be integrated. Special welding processes ensure a high welding seam qual-ity and prevent the susceptibility to corrosion in stainless steel carriers for very large corrugated metal gaskets. The corru-gated carrier can be covered either fully or partially with graphite on both sides. The construction with inner eyelet excludes interference of the operating media caused by the graphite layer and also excludes interference of the sealing system caused by the operating media.

PROPERTIES


• Complies VDI 2290 [with calculatory leakage certificate as per DIN EN 1591-1]

• Outstanding gas and liquid tightness even at low surface pressures

• Constant temperature range for graphite layer: -200 °C to approx. 450 °C [higher temperatures are possible depending on the design]

• Operating pressure up to 160 bar

• Media resistance depending on non-metallic layer and selected metallic carrier material

• No interference with the operating media caused by the gasket for the design with inner eyelet [WD20]

• Media resistance can be expanded by selecting different eyelet materials

• Fire Safe Test [Graphite]

• BAM-test report for liquid and gaseous oxygen [graphite]

• BAM-test report for ethylene and propylene oxide [graphite]

• Blow-out resistance [graphite]

• Very good elasticity and recovery behaviour

• No ageing and embrittlement even at high temperatures


• Marking on the outer edge of the gasket possible

• TRD 401 Certification [Technical rules for boilers, equipment for steam boilers of group IV] for oval gaskets for boilers

APPLICATIONS

• Established sealing system for the chemical and petrochemical sector, in conventional power and nuclear power stations, for steam generation and in device construction, especially wherever high temperatures and pressures have to be managed safely

• Gaskets for pipeline flanges, device and container flanges, for existing and new plants

• Can be covered with graphite or PTFE as non-metallic material

• Envelope gasket [PW-I]

• For higher temperatures >= 550°C with mica layer and base body made from 1.4828 e.g. for use in exhaust pipes

• Flexible or warped flange surfaces which have to seal safely at low surface pressure

• Vacuum

• Alternatives for the use of spiral wound gaskets with the following advantages:

• significantly lower necessary surface pressure

• no special requirements for the flange surface

• no media contamination with inner eyelet design [WD20]

Corrugated metal gasket with graphite layer

WS 1.4571/3803

Consists of a corrugated stainless steel carrier [1.4671] with graphite foil layer. The corrugated ring leads to a high compression of the non- metallic material at the peaks, a low diffusion cross-section, an increase in blow-out resistance and an improvement in stability and handling. This sealing system already shows a great tightness at low surface pressures and has a great elasticity and compensating ability. It is used for flanges with raised face/male and female flanges, for larger diameters in device construction as well as for special flange connections.

The corrugated ring leads to a high compression of the non-metallic material at the peaks, a low diffusion cross-section, an increase in blow-out resistance and an improvement in stability and handling. The sealing surface is reduced if only partially utilised and therefore results in an in-crease of the specific surface pressure. This design is to be preferred to the IDT profile WD10 for low bolt forces and for gaskets with larger widths.

DESCRIPTION

IDT-spiral wound gaskets consist of a spiral shaped wound combination of a non-metallic tape made from graphite, PTFE or mica and a profiled stainless steel or steel tape. The gasket spiral is fitted with a supporting ring on the inner diameter and/or a centring ring on the outer diameter depending on the application area. Spiral wound gaskets can be distinguished as follows in their design depending on the flange surface:

• Flange with raised face: Use of spiral wound gaskets with inner- and centring ring

• Male and female flanges: Use of spiral wound gaskets with inner ring

• Flanges with tongue/groove: Use of spiral wound gaskets without inner- and centring ring

Spiral wound gaskets for flanges following DIN EN 1092 are described and manufactured following DIN EN 1514-2 with regards to design and dimensions; deviating from this, the dimensions for tongue/groove applications are specified in DIN EN 1514-1, form TG. For flange connections following ASME B16.5, the ASME B16.20 as well as DIN EN 12560-2 are the norma tive basis for design and dimensional specifications for spiral wound gaskets.

Spiral wound gaskets are used specifically in high pressure applications and in critical operating conditions due to their specific characteristics profile. The gaskets are well-suited for alternating loads with accompanying component expan-sion differences in addition to the high temperature limit [450 °C for graphite, higher temperatures possible depending on the design] and the pressure operating limit [320 bar]. Spiral wound gaskets balance these differences well while also exhibiting low leakage rates.

Spiral wound gaskets comply with TA Luft 2002 [VDI 2440/2200]and the proof for VDI 2290 can also be supplied. The targeted selection of material components and variation of the set-up allows the gasket system to adjust to the requirements of many different media and operating conditions. The SD11 "Minimum Stress" [MS] version, which is optimised with regards to design and construction should be used for flanges as per ASME B16.5 [e.g. Class 150 lbs.] or for flange connections which are not suit-able for a standard spiral wound gasket following ASME B16.20 because of bolt forces.

PROPERTIES

• Managing alternating load for e.g. start-up and shut-down procedures

• Temperature resistance depending on the non-metallic material and metal materials

• Constant temperature range for PTFE: -200 °C to approx. 250 °C

• Constant temperature range for graphite: -200 °C to approx. 450 °C, higher temperatures are possible depending on the design

• Media resistance depending on the non-metallic material and metal material

• Very high pressure operating limit of up to 320 bar

• High operational safety due to broad range of applications

• Very low leakage rates for gases and liquids


• Complies with VDI 2290 [with calculatory leakage certificate following DIN EN 1591-1]




• BAM-test report for ethylene and propylene oxide [graphite]

• FDA-conform [PTFE]

• No ageing and embrittlement even at high temperatures

• Labeling for design with centring ring

APPLICATIONS

• Established sealing system for the chemical and petrochemical sector, in conventional power and nuclear power stations, for steam generation and in device construction, especially wherever high temperatures and pressures have to be managed safely

• Used in pipeline flanges, device and container flanges, pumps and valves

• Can be used for very high operating pressures and/or temperatures

• Flange roughness of Rz <=80 „µm“ is recommended

• Can be supplied with graphite or PTFE as non-metallic material, for higher temperatures >= 550°C with insert of mica or spiral made from 1.4828

DESCRIPTION

IDT-Kammprofile serrated gaskets are perfectly suited for secure sealing of flange connections in extreme ope rating conditions. They combine the specific properties of non- metallic gaskets [good elasticity to the flange surface] and metal gaskets [high stability and bursting strength]. The design allows high com-pression of the non- metallic layer, promoting low diffusion, and ensures that the serrated tips remain covered with non-metallic material, even in high surface pressure applications. In a com-pressed stage, the coverage of the serrated tip is still at approx. 0,1 mm. Flange surface roughnesses of Rz <=80 µm are re com-mended. Kammprofile serrated gaskets are described in DIN EN 1514-6 with regards to base body profiling, thickness and mate-rial of the layers. It complies with TA Luft 2002 [VDI 2440/2200]; the calculatory leakage proof for VDI 2290 can also be supplied.

PROPERTIES

• Temperature resistance depending on non-metallic layer and selected metallic carrier material

• Constant temperature range for graphite layer: -200 °C to approx. 450 °C; higher temperatures are possible depending on the design

• Constant temperature range for PTFE layer: -200 °C to approx. 250 °C

• Very high operating pressures [400 bar]

• Media resistance depending on non-metallic layer and selected metallic carrier material

• High operational safety due to broad range of applications

• Very low leakage rates for gases and liquids


• Complies VDI 2290 [with calculatory leakage certificate following DIN EN 1591-1]




• No ageing and brittling even at high temperatures

• Does not present a health risk

• Very good handling during transport, installation and dismant - ling, mechanically stable

• No excess pressing with standard tension devices

• Individual labeling of every gasket on the centring ring

MICA.Gaskets for high temperature applications.

Mica | Semi-Metallic Material

DESCRIPTION

The term Mica describes a group of minerals which have excel-lent fissility properties due to their silicate layer lattice. Mica has a lamellar non-fibrous structure and has been developed for manu facturing of gaskets for high temperature applications. Mica gaskets are used in the automotive sector, gas turbines, gas and oil burners, heat exchangers and in other flange connec-tions. Mica gaskets are made from a material which consists of phlogopite mica paper and is waterproofed with a silicone binder. A special heat resis tant steel [1.4828] provides mechanical reinforcement in the form of corrugated metal ring inserts, eyelets and/or sheet reinforcement inserts. Both the media resistance of mica as well as the metallic reinforcement and eyelet elements have to be considered for application with aggressive substances. The consicerably low loss of mass during high temperature appli-cations can be demonstrated with the thermogravimetric method. The loss of mass at 800 °C is less than 5 %.

PROPERTIES

• Weight loss at 800 °C less than 5 %

• Chemical resistance against solvents, acids, bases and mineral oils [depending on the metals used]

• Excellent temperature resistance, constant temperature up to 800 °C, short term temperature up to 900 °C

• High pressure stability depending on the metallic reinforcement

• Reinforced gaskets increase the blow-out resistance

• Does not present a health risk, can be disposed with general waste

• Mechanically stable thanks to metal reinforcements

• Pressure operating limit is restricted, depending on surface pressure up to max. 5 bar

• Non-flammable

APPLICATIONS

• Use in the area of hot gases specifically flue gas, exhaust fumes, thermal processes

• Combustion plants and motors

• Non-metallic gaskets for pipeline flanges, device and container flanges

PRODUCT RANGE

• Non-metallic gaskets • Dimensions following DIN EN 1514-1/4 and DIN EN 12560-1/4 or ASME B 16.21

• Possible as layer for Kammprofile serrated gaskets and corrugated metal gaskets and as filler for spiral wound gaskets

• Non-standard dimensions/sizes

• Mica corrugated metal gasket with or without inner eyelet

• Mica non-metallic gasket with sheet reinforcement insert, with or without inner eyelet and/or outer eyelet

RING-TYPE-JOINT-GASKETS.[RTJ].

DESCRIPTION

RTJ-gaskets are fully metallic, milled gasket constructions, which are mainly used for applications with high pressures and/or temperatures. Typical applications are in refineries in the petrochemical industry. With regards to surface quality, that the flange and the gaskets have to have an accurately treated surface without scratches and damage.

IDT-RTJ-gaskets are manufactured following ASME B16.20 [DIN EN 12560-5] and API 6A for flanges according to API 6B and ASME/ANSI B16.5 and ASME/ANSI B 16.47. Every gasket is allocated an identification number [R, BX, RX] which is described in the standard with regards to its dimensions using the ring number. A roughness of 1.6 Ra [6.4 Rz] should not be exceeded for the contact surfaces of the types R and RX; type BX requires a roughness of max. 0.8 Ra [3.2 Rz].

GASKET & PROFILE STYLES

Ring-Type-Joint-Gaskets are commonly distinguished according to two design:

• Oval

• Octagonal

RTJ-GASKETS WITH OSCULATING RADIUS

Oval Style R | Profile RJ01

The oval form can also be used in flange connections with RTJ-groove [flank angles 23°] according to the above mentioned norm. The spherical surface of the gasket is pressed against the cone surface of the flange when clamping it, which creates a linear contact between flange and gasket. The metal ring is deformed further with increasing assembly force and the contact surface is widened. The size of the sealing surface there-fore depends on the applied assembly force; the oval shape is preferred if the bolt forces are low and the radial elongations/offsets vary.

RTJ-GASKETS WITH RAISED SEALING SURFACE

Octagonal Style R | Profile RJ10

The octagonal design can also be used in flange connections with RTJ-groove [flank angles 23°] according to the above mentioned norm. Different to the oval form, an extensive stress is created right from the start on the contact surface gasket/flange. The sealing surface size is therefore independent from the assembly force; the octagonal type is the the preferred design.


Octagonal Style RX | Profile RJ20

The type RX is an optimised design of style R: octagonal. The gasket type fits the same groove flange as described for the R style and can also be easily used or replaced in this application. The RX style was optimised in such a way that the overall seal-ing force is increased via the internal pressure, and which in turn influences the gasket properties positively. This design can be fitted with an additional pressure balancing hole.


Octagonal Style BX | Profile RJ30

The BX style is also a pressure optimised design; BX style can, however, not be exchanged with other styles and has been deve-loped specifically for the API 6BX flange. This design can be fitted with an additional pressure balancing hole.

PROPERTIES

• High tightness, considered technically tight


• Chemical/mechanical/thermal resistance depending on the material


APPLICATIONS

• Gaskets for pipeline flanges, device and container flanges, pipeline construction and device construction

• Established gasket system in the chemical and petrochemical industry, in conventional power stations and nuclear power plants

• In device construction; specifically where high temperatures and pressures have to managed safely

• For high internal pressures and/or high temperatures

• For vacuum

MATERIALS

Because RTJ-gaskets are used in extreme operating condi-tions, it is of utmost importance to select the most suitable, metallic material. In addition to pressure and temperature, the resistance towards the conveyed media has to be con-sidered. The hardness of the gaskets should usually be lower than that of the flange material in order to prevent mechani-cal damage to the flange.

The maximum values for the hardness are specified for the different materials as per ASME B 16.20 / API 6A.

DESCRIPTION

Lens gaskets, also known as sealing lenses or high-pressure lenses are fully metallic, turned sealing elements. Lens gaskets are mainly used in high pressure applications and specifically in pipeline flanges. The machined flange surfaces form a cone segment with an opening angle of 140°. The spherical zone of the lens connects here to the cone surfaces of the flange. Lens gaskets are not sensitive to overloading; an increase of the forces leads to an increase of sealing surface, which means that the surface pressure does not increase proportionally. It is recommended that the hardness of the gasket is lower than that of the flange since the lens sealing surfaces easily deform. Experience has shown that even if the materials are the same, the plasticity of the lens gaskets is significantly more pronounced. Normally, the welding neck flange of the associ-ated pressure stage specified in DIN EN 1092-1 is used; other, equivalent flanges are, however, permissible. A roughness of Rz <= 6.3 in radial direction is necessary for the sealing sur-faces. The flange and the gaskets have to have an accurately treated surface without scratches and damage. In addition to the standardised lens gaskets specified in DIN 2696, an addi-tional system with spherical zones as sealing surfaces is used - mostly in the chemical sector and device construction. Detailed information about this system can be found in the respective company standard.

PROPERTIES

• High technical tightness


• Good handling, mechanically stable

• Blow-out resistant

• Very good handling during transport, installation and dismantling

• Individual marking of each gasket on the outer edge

APPLICATIONS

• For pipeline and device construction


• For flanges from DN 10-200 and PN 63-400

• For vacuum

PRODUCT RANGE & DESIGNS

INSERT RINGS.

Metallic Material | Insert Rings

DESCRIPTION

Insert rings are fully metallic, turned rings which are standardised following DIN 2512. They are commonly used with two non- metallic gaskets in groove/groove flange connections.


The standard design is a simple smooth ring [ER01]. Insert rings are often equipped with a Kammprofile serrated profile on the sealing surfaces in order to improve the sealing pro-perties [ER10]. A very practical solution is to use insert rings which are serrated on both sides and are covered with graphite foil. These insert rings are like a Kammprofile serrated gasket and the two additional non-metallic gaskets which are usually required for standard insert rings are not needed.

WELD RING GASKETS.

Weld Ring Gaskets | Metallic Material

DESCRIPTION

Weld ring gaskets are commonly used in areas where danger-ous media is conveyed and/or continuous operation of the plant has to be ensured. A permanent and gas tight connection is established by welding the membrane or weld ring halves. This ensures the required high operational safety and continuity, while it is still possible to release the flange connection by undoing the welding seam.

Weld ring gaskets consist of two identical ring halves which have been machined with greatest precision, were welded to the flange surface and then welded together after positioning the flange halves.

IDT-weld-ring-gaskets are manufactured following DIN 2695: 2002 for DIN- and ANSI/ASME-flanges [SW01, SW10] and according to company standards [SW19, SW20, SW29]. The thickness of the welded rings is 2 x 15 = 30.0 mm for the designs SW10 and SW20, which allows for the welding of the ring halves without a special flange. The SW19 profile provides an additional auxiliary gasket. Prior to installation, the flange surfaces need to be checked for sufficient space.

Weld ring gaskets with additional auxiliary gasket are used when:

• The pressure test is done without welding only with the auxiliary gasket

• The flange connection is opened several times during start up

• Welding is only carried out if the auxiliary gasket does not achieve tightness

The use of weld ring gaskets with hollow lips is recommended [SW20, SW29] for the connection of components with differ-ent heat expansion properties. The advantage is in the greater movement absorption and is therefore commonly used for dif-ferent radial expansion ratios of the components.

PROPERTIES

• High tightness, considered technically tight

• High operational safety

• Connection can be detached if necessary


• Good handling

APPLICATIONS

• For pipeline and device construction


• For vacuum

• For applications in which the operation has to be ensured continuously

• For critical media

DESCRIPTION

Boilers are pressure equipment at risk of overheating in the sense of the pressure equipment guideline 97/23/EG and may only be sold if the manufacturer has provided proof that the necessary safety requirements of this guideline were adhered to by means of a conformity assessment procedure. The manufac-turer applies the CE-label and issues an EU-conformity declaration.

Harmonised product standards for boilers are:

• DIN EN 12952-1 up to 17: Water tube boiler

• DIN EN 12953-1 up to 14: Shell boilers

• DIN EN 14222: Stainless steel shell boilers

Different norms and regulations may also be applied. However, the manufacturer has to prove that he has fulfilled the necessary safety requirements of the pressure equipment guideline.Boilers or boiler plants have great risk potential due to the high stored energy and the high inner pressure. They are therefore plants which require monitoring as per the operational safety directive. Based on these regulations:

• boilers have to be checked by an approved inspection authority prior to commissioning

• approval for operation has to be obtained from the relevant authorities

• in certain intervals checks have to be repeated [inner and exterior checks, strength tests, functional test of the safety devices] by an approved inspection authority

In order to prevent possible risk when using non-metallic gaskets for sealing cover systems in boilers, the requirements for the relevant gasket system has been specified in the VdTÜV-infor-mation leaflet "Gaskets 100" [previously TRD 401, Technical Rules for Boiler]. The requirements in the clamping system and gasket, the test conditions and the marking of the gaskets are specified there.

The tests are carried out by VdTÜV. If the test results are posi-tive, then the component approval mark is awarded which has to be applied to the tested gasket. VdTÜV information leaflets are important with regards to the adherence to the pressure equipment guideline and the fulfilment of the AD 2000-policy. Boilers are fitted with access openings which are used to access the interior for revision work. The selection of the design is done in consideration of the condition of the clamping system. Boilers are equipped with oval sealing covers and interior lid. The lid is clamped using nuts and brackets and has a self-sealing effect in the event of overpressure.

The following IDT-boiler gaskets were specifically developed for use in oval sealing covers and meet all test requirements of the VdTÜV.

DESCRIPTION

Normally a glass lined or enameled protection ring following DIN 28153 is used to reduce the impact and shock stress of the manhole connector. This operational practice has shown, however, that the glass lined protection ring is so severely sub-jected to the impact and shock stresses due to regular opening, closing and filling cycles that is has to be replaced frequently at high cost. Chipping of the enamel layer, especially on the inside of the manhole, filling and sampling connector can even cause expensive repairs or require a new glass lined layer for the entire container. In addition to these repair costs, there are also high losses due to production interruption of the plant operation. Fur-thermore, this design also provides the risk that the upper seal may slightly buckle when the vacuum is applied and therefore becomes untight.

The IDT-PTFE manhole protection and sealing ring was deve loped to have an intermediate ring made from chemically resistant PTFE protecting the glass lined connector inside wall against impact and shock stresses. The protection ring is equipped with an apron that reaches inside the connector. We recommend the use of conductive PTFE to prevent electrostatic charges. The manhole protection ring is fitted with an O-ring seal on both sides to achieve gas tightness. This O-ring seal consists of elastic FPM material with or without PTFE-jacketing and has a con-centric Kammprofile serrated gasket on the top and bottom to create a liquid seal.

These two features allow safe sealing at low surface pressure. A stainless steel sleeve ensures bursting safety for interior pres-sure as per the requirements of the pressure equipment guide-line. The calculatory proof has been provided by IDT and is TÜV confirmed [suitability and design].

The height of the sleeve is approx. 70 % of the thickness of the base body, the thickness is greater than 2.5 mm. The sleeve can be fitted on the outside with retaining brackets in order to fix the manhole ring to the container connector and to prevent possible leakages by slipping. These brackets also ensure electrostatic discharge and possible spark discharge is safely avoided. The following distinction is made with regards to the opening and closing mechanism and the allocation of the connector:

• Sealing cover only hinged [oval manhole] flat or convex or concave with a centrally located connector

• Sealing cover hinged or with pivoting device [oval and round manhole]

• Hinged, convex with an eccentrically located connector

• Pivotable, convex with an eccentrically located connector

• Pivotable, convex with two symmetrically located connectors

PROPERTIES

• Almost universal resistance against chemicals and solvents

• Blow-out resistant sealing system

• Avoids expensive repairs or re-coating of the of the entire boiler

• Avoids use of expensive glass lined intermediate rings and seals don't have to be replaced as frequently

• Has a long service life even in batch operation and during frequent opening and closing

• Conductive [discharge of electrostatic load], body made from conductive Dyneon™ TFM TM

APPLICATIONS

• Operating pressure max. 10 bar

• Operating temperature approx. 200 °C

• Flange sensitive to stress

• Aggressive and toxic media in gaseous and liquid states

• Pharmaceutical and chemical industry

• Batch operation [temperature and pressure changes]

BLIND GASKETS.

DESCRIPTION

Blind gaskets are used when locking a pipe for maintenance tasks or to perform pressure tests. The materials, permissible temperatures and pressure level will generally be specified in a pipe class. Where that is not the case, the required thickness of the blind gasket must be calculated in accordance with AD 2000 B5 or DIN EN 12952.

SEMI-FINISHED, MOLDED, TURNED & MILLED PARTS.DESCRIPTIONOur focus in plastics is on processing PTFE material for struc-tural components, like plug inserts and accessories, V-collars, seat rings, bellows, bearing shells, cover gaskets, pig compo-nents, and O-rings. For the majority of these parts, we use the high quality materials supplied by Dyneon®. The most popular materials include the modified compounds 3M™ Dyneon™ TFM™ 1600, 1700, 4105, and 3M™ Dyneon™ TF 1602; other materials with fillers made of conductive pigment, graphite, or bronze are also avail able as standard options. The manu-facturing and processing of plastic molded parts to specifi-cations from drafts, drawings, or patterns is done on state of the art CNC machines [e.g. milled, water jet shape cutting, CNC/NC turned, seamless processing up to Ø 1,600 mm]. The semi-finished parts are also manufactured in our own in-house production to ensure flexibility and value even in small production quantities.

DESCRIPTION

Stuffing box packings are proven sealing solutions for use in pumps, agitators, and for spindle gaskets in regulating and con-trol valves. Stuffing box packings are manufactured from yarns in braiding machines using various braiding types depending on dimension and packing type.The materials used consist of organic natural fibers, organic syn-thetic fibers, or inorganic synthetic fibers, including: Aramid, PTFE, ramie, novoloid, panox, polyacrylic, glass, aluminium silicate, carbon, pure graphite foil, and PTFE compounds. Depending on type and area of application, packings can additionally be manu-factured with lubricants, fillers, and binding agents.

Important to note for installation:

• Only use packings that match the relevant stuffing box dimensions

• Remove residues of old packings, and carefully clean the stuffing box

• The surface must be free of scoring and traces of rust

• The gap between shaft and housing or spectacle must be < 0.2 mm. For greater gaps, extrusion-resistant packings or O-rings must be used

• Do not try to hammer packings to size

• Use appropriate mounting and removal tools

PRODUCT RANGE

Bulk goods in cartons 1 kg: 3-7 mm vkt. 2 kg: 8-11 mm vkt.3.5 kg: 12-14 mm vkt. 5 kg: 15-19 mm vkt.10 kg: from 20 mm vkt.Ready to install, form-pressed packing rings according to size

TA LUFT PACKING SETS

Valves are the most common components in plant construc-tion. The stuffing box packing, which seals the spindle passage in the valve housing ensures high operational reliability. That is why packings for the stuffing box space, spindle, gap, and the packing dimensions have to comply with specific requirements and special care. There are specific installation and commis-sioning instructions for TA Luft packing sets to achieve the leakage rates required by TA Luft 2002 [VDI 2440/2220], which we can provide on request.

10 EXPANSION JOINTS.

172172

DESCRIPTIONExpansion joints are components used in pipeline, plant, and device construction. They are designed to withstand the same stresses as plant components and pipelines; additionally they must absorb added stresses, movements, or vibrations in axial or lateral direction. The main area of application for fabric expansion joints are plants conveying gaseous media. Precise technical installation data from the user are essential for optimised expansion joint designs to ensure a perfect fit for the relevant usage conditions in industrial plant construction.

PROPERTIES• Optimised flexibility and highest possible mobility with a low construction height [pipeline gap]

• Resetting/adjustment forces move towards the zero point or are negligibly small in calculations

• A multitude of possible material combinations allows optimised and customised adjustment to prevailing operating conditions

• The manufacturing of large size expansion joints is inexpensive

• Material folding ensures lower transporting costs for large sizes

• Easy installation, can often be carried out by customer's own personnel

APPLICATIONSPower plants, waste incineration plants, dust removal and filter systems, cement industry, steel industry, drying technology, chemical industry, conveyor technology, fan construction, ventilation technology, marine engineering, etc.

MATERIALThe multitude of possible material combinations allows the development of optimised solutions, which are generally influenced by prevalent mechanical, chemical, and thermal conditions. The structure of the expansion joint is generally based on the following material groups:

Insulation materialInsulation material in an appropriate thickness and quality will prevent thermal as well as mechanical damage to the actual sealing foil. The most frequently used insulation material fabrics are glass fiber, silicate fibers, and ceramic fibers.

Sealing foilThe sealing foil is the actual sealing component of an expansion joint. It is generally sandwiched between two layers of fabric. The most frequently used sealing foils are made of elastomeres, PTFE, or stainless steel.

Carrier fabricPositioned on the outside of the sealing foil, the carrier foil [ge nerally coated] provides the necessary compression strength and dimensional stability. The most frequently used carrier fa brics are made from polyester, aramid, glass fiber, or silicate fibers.

CoatingThe carrier fabric is protected by a coating of various elastomeres, which additionally supports the shape of the expansion joint, and serves as the actual sealing element in simpler construction elements. The most frequently used coatings include neoprene, EPDM, hypalon, silicon, viton, and PTFE.

MOVEMENT SURVEYThe movement survey capacity of the expansion joint depends primarily on the model type of the centre part [AR]; the following are the most common structures:

CENTRE PART AXIAL ~ LATERAL ~

Concave 0.3 x AR 0.15 x AR

Straight 0.25 x AR 0.1 x AR

Pleated 0.25 x AR 0.3 x AR

Expansion Joints | Fabric Expansion Joints

MODELSTube expansion joint I Attached to te pipe Suitable for round or oval crosssections. Mounting strips must be used for rectangular crosssections, and the duct walls must be drilled. For a vacuum system it is important to note that the expansion joint bellows will pull inward and constrict the flow diameter.

In these cases, support rings must be installed. Max. ope rating temperatures must not exceed 350 °C, as the fixing point will take on the temperature of the medium. The attachment of the joint is implemented using multipart hose clamps for sizes between Ø 700 mm and 800 mm.

For larger diameters, flange connections are recommended due to their higher sealing capacity.

Tube expansion joint I Attached to extracted mounting flangeThis installation model covers all crosssection shapes and sizes. Rectangular connection points will require adequate hose diameters, and a drilling of the duct is not required. Due to the good temperature reduction properties in the attachment area, an implementation without preinsulation will be suitable for temperatures between 400 and 500 °C, and with preinsulation for temperatures between 600 and 700 °C. With relevant structural measures in place, i.e. inner brickwork lining, temperatures up to 1000 °C will be manageable.

Flange expansion joint Suitable for use for large dimensions or preexisting pipeline flanges, higher pressures, and high technical tightness requirements. Due to the inferior heat radiation in the attachment area, operating temperatures should not surpass 450 to 500 °C. With the use of larger flanges, the expansion joint can be placed further outward [away from the flow of the medium], and additionally protected by another insulation or retrofitted insulation. This will allow operating temperatures between 600 and 650 °C.

DESCRIPTIONHandling of the 9370 flange spreader is simple: Once two counter-positioned connection bolts have been removed from the flange, the flange spreaders can be driven into the newly vacant holes.

All remaining connection bolts are subsequently removed or loosened and the flange connection is opened using the pressure bolt in the flange spreader.

A rigid spacer should be inserted between the flange sheets for additional safety. The gasket can now be replaced. The system allows the flanges to be spread open enough to allow inspection. Any damage of the flange contact surface is pre-vented. Not only gaskets, but also measuring targets, blind gaskets, and other items be replaced easily.

AREAS OF APPLICATION FOR DIN FLANGES Flange spreaders can also be used with other flange types. We recommend using two flange spreaders concurrently, as a flange connection should always be spread parallel.
