S jointaccording to joint system C, glazed inside and out (DN 200 glazed inside)
DN 200 S joint, unglazed on the outside
L joints consist of a profile ring to align the spigot; the seal is made of SBR and EPDM.
K joints consist of a compensating element within the joint (polyurethane, rigid) and
a sealing element attached to the spigot (polyurethane, soft).
Pipe systems fitted with an S joint consist of a ceramic-rubber seal. After firing, the socket and the spigot are ground with high
precision to the required size. An EPDM sealing ring is attached to the spigot during the manufacturing process.

KERAPORT | Manholes
Extremely corrosion-resistant and leakproof.
Manholes, like every other sewer system component, need to meet increasingly greater requirements. For a number of reasons, effluent is now significantly more aggressive than even just a few years ago. A major aspect, to name just one example, is the fact that people use more warm water than in the past, which has led to changes in the chemical reactions that take place in the sewer system. In addition, wastewater now often has to be transported across further distances. Reliable sewer systems must therefore provide maximum levels of corrosion-resistance and tightness on a permanent basis. As such, there is a growing focus on the quality of manholes in sewer systems, both for public sector and private customers.
For sewage treatment plants to work efficiently, sewer infiltration water from leaky sewer manholes must be avoided at all costs. Steinzeug-Keramo optimally meets this requirement profile with its KeraPort range of manholes. Like no other material, vitrified clay stands for corrosion-resistance and tightness in wastewater transport. Every vitrified clay manhole is manufactured according to individual specifications.

BASICS | Planning principles
36
PLANNING.IMPORTANT BASIC PRINCIPLES.
Reliable quality
Pipes and fittings that comply with prevalent standards are characterised by their invariable prop-erties – above and beyond their service life as sewer pipelines. This is subject to the one essential condition that they must be planned, installed, operated and maintained – inside and outside buildings – in accordance with the requirements stipulated in EN 752, EN 1610 and EN 12056.
37
Hydraulic technology
In the hydraulic planning of vitrified clay pipelines, the values of wall roughness correspond to the values of all the other raw working materials. This applies to the entire service life of drains and sew-ers that are affected by deposits and biological slurry. Either the Colebrook-White (Prandtl-Cole-brook equation) or the Manning/Strickler method can be used as calculation methods.
Static calculations
Vitrified clay pipes and fittings are considered bend-proof for the static calculation of drains and sewers according to the methods defined in EN 1295-1. Due to their own load-bearing capacity, they can directly bear soil and traf-fic loads. Throughout the entire service life of drains and sewers, there should be no cases of pipe deformation or changes to the pipe diameters caused by external or in-ternal load effects.
The manufacturer provides information on the nominal wall thickness and/or the wall outer diameter. The strength of vitrified clay pipes and fittings remains invariable through-out the entire service life of drains and sewers. Further-more, vitrified clay pipes are resistant to alternating stress from road and rail traffic.

INFOPOOL
STATICS CALCULATOR
INFOPOOL
38
Operation and Maintenance
Drainage and sewer systems made of vitrified clay pipes and fittings meet the requirements of EN 752 and EN 12056. They are considered as ready-to-use and fully functional at all times.
Reasons: . The high chemical resistance of vitrified clay pipes and fittings and their joints . The functional properties of the pipes, that remain unaffected by effluent . Easy removal of existing deposits from the smooth ceramic inner lining of the pipe, which remains unchanged throughout the system’s entire life cycle . High resistance to high-pressure water jetting . High resistance to the effects of mechanical cleaning equipment and other maintenance devices . High mechanical resistance to abrasive wear . No restrictions of daily operations during rehabilitation measures – either when replacing pipes in open or trenchless construction, or in repair or renovation processes
Additional information can be found in 1610, EN 12889 and EN 752.
Installation
Installation of vitrified clay pipes and fittings in open trenches is to be done in compliance with EN 1610. Using flexible joints ensures flexibility in underground drainage systems – the pipe system can adapt itself to soil settlements and movements. Suitably flexible joints are also used for connecting pipelines to entry and inspection manholes and buildings, and help to counter additional strains and stresses from uneven settlements between the pipes and the building structure.
BASICS | Planning principles
39
Environmentally soundSafety, tightness and reliability are important factors for environmental soundness. Vitrified clay pipe systems comply: they behave neutrally in soil and groundwater, i.e., no exchanges take place between sewage/soil/groundwater via the material. Resistance to abrasion and corrosion are also ensured. It goes without saying that the natural character of this raw material, its mining, and the 100 percent recyclability also speak for the eco-friendliness of vitrified clay.
Intergenerational equityUsing vitrified clay pipes for sewage system construction saves future generations the constant financial burden of maintenance and renovation work. The expected life cycle that exceeds a century represents significant savings in terms of resources and capital.
Cradle to Cradle®-certifiedCM
In contemporary manufacturing processes, used materials typically end up in the “grave”, i.e., the waste container or incinerator. With the implementation of Cradle to Cradle®, products and all their components flow as resources in infinite material cycles. The program marks a mindset change from a linear system with a beginning and an end to an infinite “loop” system.
Read more on page 58.
EconomicalThe long service life of more than 100 years and the low maintenance requirements of vitrified clay sewage systems are crucial parameters for their cost-efficiency. With only minimum asset erosion, they maintain their value as a fixed asset. Local authorities ultimately have a social duty to ensure that sewage disposal is financed via the wastewater charges. With vitrified clay pipe systems, the sewage system is refinanced over the long service lifetime with low depreciation rates (1.0 – 1.5 percent) and consequently low fees. Affordable and one-time establishment of wastewater disposal is a special obligation.
Installation guide according to EN 295 and ZP WN 295. The installa-tion of drains and sewers is regulated on a European level by EN 1610 “Construction and testing of drains and sewers.” In some areas, these regulations are additionally amended with manufacturer specifications.
Without exception, all installations of vitrified clay pipes and fittings for drains and sewers and all ensuing tests for tightness are carried out in compliance with EN 1610. Please read on for more details..

DELIVERY
Components Vitrified clay pipes are standardised according to EN 295, parts 1 to 7, “Vitrified clay pipes and fittings and pipe joints for drains and sewers.” Furthermore, the products are manufactured according to the certifica-tion program ZP WN 295, which includes even higher requirements than EN 295.
Due to the implementation of the norm in building regulations, a special authorisation of the products by Deutsches Institut für Bautechnik (DIBt, German Institute for Civil Engineering) is not necessary.
Quality assurance is provided by self-monitoring and external monitoring, with DIN CERTCO as the external monitoring body for vitrified clay prod-ucts. The DINplus mark on all products (label on every pipe and fitting) guarantees the technical properties according to EN 295 and ZP WN 295. It also verifies that a quality management system according to ISO 9001:2008 is in place and has been applied.
CONSTRUCTION WORK | Delivery
42
UNLOADING AND TRANSPORT
STORAGE
Pipes are safely stored at the con-struction site with the aid of the mini-in-maxipack packaging system. Individual pipes need to lie on timber beams; fittings are stored either on mesh pallets or individually upright on the socket.
CONSTRUCTION WORK | Unloading and transport, storage
In cooperation with our business partners, we can directly deliver to any con-struction site efficiently and on time using our safe reusable packaging sys-tem.
At the construction site, the pipes and fittings can be unloaded with ease and examined for possible transport damage. This examination is done by dust-ing the shaft ends with talcum powder. Any further transport of pipes and fittings on the construction site itself also has to be carried out with suitable machinery.
43
INSTALLATION
Avoiding errors
As a matter of principle, only the original KeraMat lubricant that is included in every delivery may be used.
Vitrified clay pipes of small and medium diameters can be inserted with a wooden timber and a crow bar. Pipes with larger diameters are assembled with a grip hoist or winch.
When manufacturing pipe joints in DN 200 and above, it must be ensured that the marking of the pipe crown is face up. When installing junctions in DN 350 and above, it is important to differentiate between the junctions that feed in from the left and the right.
The vitrified clay pipes must be installed in such a way that they are on a level with the shaft and positioned centrally in the trench. Socket holes have to be dug for the sockets.
In case of frost, the trench floor has to be protected as vitrified clay pipes must not be installed on frozen surfaces. Installation can still take place in temperatures below 0°C as long as the necessity for slightly higher insertion forces, depending on the outside temperature, is taken into consideration. Comparably, the seals are tested up to a temperature of -10°C.
For nominal sizes larger than DN 1000, the pipes are inserted horizontally into the guide ring.

The method of supporting and bedding the pipes has a major influence on the positioning and load-bearing capacity of the pipeline.
The vitrified clay pipes must be installed in such a way that they are on a level with the shaft and that neither linear nor selective support occurs and a uniform load distribution is guaranteed. As mentioned before, pipes should be placed centrally in the trench. The minimal width of the trench according to EN 1610 must be adhered to.

Recommendation:Use the total trench width to install the concrete bedding
INSTALLATION | Embedment and Support
In special cases, hydraulically bound material such as concrete is used as bedding material. Construction measures or static conditions may have an impact on determining the concrete bedding.
Concrete bedding with an effective support angle of 90°, 120° or 180° cor- responds to bedding type 1 according to EN 1610. The width is calculated via the a value (a = 10 cm + DN/10) or the trench width.

COMPACTION AND BACKFILLING
Mechanical compaction is carried out in layers of 15 to 30 cm.
When using vitrified clay pipes, for grain sizes >40 mm in the first layer of the main filling to be compacted, the cover layer has to be at least 300 mm thick.
Recommendation:If possible, use the in-situ soil as filling material for the trench.
Manhole connections and connectors
Supple short pipe connectors are used to compensate for settlements/ground irregularities between, for in-stance, manholes and the pipeline. The flexibility of the pipe joints can incorporate any settlements.

IMPORTANT REGULATIONS.CLEAR RECOMMENDATIONS.
TESTING | Regulations
Warning:Due to the increased risk of danger in pressure tests, particularly when testing air pressure, no persons are allowed to stand in the area of the fixing device while such tests are taking place.
Testing the installed pipelinesAfter the pipelines have been installed, the following inspections and/or tests according to EN 1610, section 12, need to be carried out: visual inspection, tightness, embedment zone, main filling, compaction and pipe deformation (not necessary for vitrified clay pipes). Tightness tests for pipelines, manholes and inspection chambers are to be done according to EN 1610, section 13.1, either by means of the air testing method (L) or the water testing method (W). A preliminary test can be carried out before the side bedding is added. Approval tests require the testing of the pipelines after filling and removal of the trench lining material. When performing the test for open trench construction, the connections can be tightly sealed with stoppers and spring clips or rapid-fit stoppers (only testing method W). Fixing devices are to be secured against movements and must be form-fit! Leakages in the sealing devices and the testing device must be avoided. With testing method W, proof of tightness is determined via the water loss under test pressure during the testing time (value W30), and with testing method L, via the value of pressure drop during the testing time.
Recommendation: Use air pressure test method LC 100
Test method (W), water pressure test for EN 1610Test pressure: 0.1 up to 0.5 barTesting time: 30 minutesPreliminary testing time: 60 minutes
Water addition limit W30Pipeline: 0.15 l/m2 Pipeline and manholes: 0.20 l/m2 Manholes and inspection chambers: 0.40 l/m2
In a water pressure test, the section to be tested is to be filled without pressure from the lowest point. Air is expelled at the highest point of the test section. The test pressure is applied at the lowest point.

TESTING | Regulations
Pipe deformationIt is not necessary to test vitrified clay pipes for pipe deformations.
Individual socket testsIf a socket test is necessary for technical reasons, all used test devices should be double packer devices to minimise leaks between packer and pipe wall.
Due to the complex and error-prone measurement tech-nology, all results from individual tests are assessed in a deviation evaluation, in relation to the pipeline length.
CCTV sewer inspectionTesting and assessment of the findings are two separate CCTV sewer inspection services. The assessment must take into account the technical conditions of the pipes, fittings and joints at the time of delivery.
Recommendation:Settling time for the air pressure test: up to DN 500: min. 5 minutesfrom DN 500: DN/100/minutes
N.B.:EN 1610: The test protocol has to be prepared individually for each test. As a service for our customers, we provide protocols for air and watertightness tests upon request.

STEINZEUG-KERAMO COMPACT | Standards
Resistance to chemical/physical attack mechanical stresses
The functionality of the pipes is not affected in any way at all by external factors – both in terms of safety and their reliability for sewage water transport.
Naturalness of the raw materials Clay, water and grog – the mixture is as natural as it gets. And the environment benefits right from the word go.
Strength, tightness and hardness All three properties stand for the long service life – no other pipe material can lay claim to practical experience spanning around 3,000 years.
Abrasion and corrosion resistance Even long-term stress has no impact on the reliable functional properties, whether in the form of acid attack, abrasion or sewage deposits.
Stability of the properties under the influence of wastewater, groundwater and soil The properties of vitrified clay are literally “set in stone” – irrespective of the surrounding environment.
Neutral behavior towards groundwater and soil Drinking water comes from groundwater, our ground serves agriculture – it is therefore all the more important to make no impact, to trigger no reactions, to leave no deposits.
Service life Vitrified clay stands for a success story that goes be-yond a lifetime – in terms of the environment, economic viability and sustainability.
Maintenance and repair costs Both are low – which is not only good for public funds, but also saves future generations from investment back-logs.
Recyclability Natural raw materials are returned to the natural cycle, thus relieving the strain on nature, resources and pro-duction.
Environmental aspects Vitrified clay meets all the requirements of an environ-mentally relevant material – from the mining of the raw material to the manufacturing process to recycling.
Sustainability With vitrified clay products, the three pillars of ecology, economy and social responsibility stand on a firm foun-dation. No other material is so sustainable.
Cradle to Cradle® Like nature, vitrified clay undergoes a closed cycle – without any waste, with only a minimum use of resourc-es, and without burdening the environment.
