Our company – Esta Rohr GmbH – has been producing stainless steel pipes in our factories for 40 years on behalf of exacting customers with an array of different require-ments. As a German pipe manufacturer, we are committed to offering products of the highest quality.

Such sectors as the automotive industry, process engineering, forming technology and design engineering have been using Esta Rohr pipes successfully for years. All the machining and finishing processes essential for our stainless steel pipes are incorporated into the production flow. This includes laser welding, post-weld dressing (inside and out) and solution annealing. In-production quality controls that go far beyond the standards required complete our 'Made in Germany' production profile.

Our expertise in installation technology was demonstrated from the very first moment our proven simplesta® ST stainless steel piping system for drinking water lines and numerous other applications was used.

Pipe dimensions from 15 to 108 mm and the practice-driven fitting programme are processed using the latest pressing technology (M-profile).

First-class and proven:Our products build on 40 years of experience.

'Stainless steel' has become a generic term for the large group of corrosion-resistant steels. VA, inox or rust-proof steel are other colloquial names or trademarks. Improving or adapting the properties to meet new requirements by mixing (alloying) iron with other metals or materials has been a continuous goal since the Iron Age (eighth to the fifth century BC).

The research laboratories of Friedrich Krupp discovered the solution in 1912. Alloys with a chromium content of more than 12% or combined with nickel and carefully balanced heat treatment delivered the foundation for technical application.

The process was submitted for patenting on 17 October ofthe same year. To this day, these steels do not need to be

painted, coated, galvanised or undergo any other corrosion protection measures when treated properly.

The simplesta® ST stainless steel piping system capitalises on system piping made using stainless steel with the material number 1.4401 and ferritic stainless steel with the material number 1.4521. The defining main alloying elements are chromium and nickel in the case of 1.4401 and chromium and molybdenum in the case of 1.4521. In particular, mo-lybdenum improves the pitting resistance of 1.4401 and 1.4521 by 2.0 to 2.5%.

Stainless steel has a future:1.4401 / 1.4521

1.4401 and 1.4521 are materials that enable the user to draw on more than 40 years of experience in a multitude of different applications.

These materials deliver good value for money and the gre-atest degree of safety in sanitation installations. Esta Rohr pipes made using 1.4521 ferritic stainless steel are also a cost-efficient and stable foundation for combating price fluctuations on the commodity exchanges.

The materials are optimised for the simplesta® ST stainless steel piping system during the normal analysis. The molybde-num values at Esta Rohr are above the minimum values and special solution annealing increases the corrosion resistance of the pipes. The high degree of corrosion resistance is achieved through an extremely dense and stable chromium oxide layer of only a few atoms in depth, preventing the oxidation of the underlying base material.

We deliver the laser-welded pipes in the sizes 15 x 1 mm to 108 x 2 mm. Esta Rohr has the experience and production techniques needed to process the material properly.

Perfectly compatiblecoupling technology

The simplesta® ST stainless steel piping system consists of the 1.4401 or 1.4521 stainless steel pipe and the accompanying 1.4401, 1.4404 and 1.4408 stainless steel press fittings.

The M-profile crimped joint has been a technical and economic step forward compared to conventional joining techniques, such as soldering, welding and screwing, for more than 50 years.

Application is perfectly safe and hygienic, as well as satis-fyingly durable if the guidelines and recommendations are

observed. All the components needed for proper connection are part of an integrated system, are designed for compa-tibility as per the DVGW‘s (German technical and scientific association for gas and water) W 534 worksheet and are certified in accordance with the DVGW‘s DW-8501CM0584 system approval. Safe, simple and quick to process, the system offers durable stainless steel quality and all the com-monly known benefits of pressing technology.

Application is perfectly safe and permanently corrosion resi-stant if the guidelines and recommendations are observed.

The blue press indicator at the end of the fittings makes your installation even safer. It is a simple means of visual control for the installation engineer. The press indicator will only drop off if the pipe‘s crimped joint is secure.

The wording of the warranty statement and indemnification agreements with the ZVSHK (German sanitation, heating and air conditioning association) confirm the safety of the simplesta® ST stainless steel piping system.

Sound advice and practice-driven service by the manuf-acturer (Esta Rohr GmbH) not only round off the system, but also the requirement for certainty in all technical and commercial questions.

7

Working on the safe side –simplesta® system pressing tools

Pressing tools are a combination of pressing device (power unit) with pressing jaws and/or pressing collars and adaptor jaws.

The system pressing tools designed for the simplesta® ST stainless steel piping system are made by Novopress and can be purchased through the Esta Rohr GmbH. Press fit-tings, pipes, and pressing tools have been specially designed for compatibility to ensure the reliability of the entire sys-tem.

With that in mind, we recommend the use of Novopress pressing tools to prevent possible complications arising from the use of tools not belonging to the system. The pressing jaws and pressing collars must have the M- profile.

The pressing tools must be serviced regularly to ensure their safe operation. See the operating instructions of the pressing tool for more information on the above, as well as for general handling and safety notes. We strongly recommend that you read the operating instructions and follow the information provided before using for the first time. Servicing is carried out by Novopress directly (with service log and labels).

Cutting and deburring for all dimensions from 15 to 108 mm

Cutting The pipes can be cut using the following tools:• pipe cutter• fine-toothed hand saw• metal cold circular saw

Unsuitable:• plasma arc cutting/burning• cutting with an angle grinder (this includes

discs classified as suitable for stainless steel)• saws with oil cooling/cooling lubricants

Deburring The piping must be carefully deburred internally and externally after cutting. To do this, use: • hand deburrer (available in various versions)• electric pipe deburrer External deburring is of particular importance so that the seal ring on the fitting to be slipped on is not damaged. Finally, any swarf must be removed from the pipe‘s inner surface (so that no swarf becomes caught between seal ring and pipe) and outer surface (so that as few particles as possible enter the pipe system during installation).

The following generally applies: • separation cuts must always be made completely.

Partly cut pipes may not be snapped off, as the partially high degree of strain hardening in the area of the break reduces corrosion resistance

• there must be no heat tinting on the surface of the material. Heat tinting is surface discolouration caused by the oxidation of atmospheric oxygen on heated areas. The colouring consists of light shades of yellow to begin with then turns blue followed by brown

• As a simple yardstick for the work site, the surface must have a bare and typically steel-grey appearance for full corrosion resistance.

• the tools must be suitable and approved by the respective manufacturer for stainless steel

• the tools should not be used for working with other materials. In particular, they should not come into contact with normal, non-alloy steel (carbon steel). Corrosion may occur if normal steel particles transfer to the stainless steel surface

• a plastic bottle brush may be used to remove any swarf from inside the pipe. Steel brushes may not be used

61

Marking the insertion depth

INSTALLATION

The appropriate insertion depth must be marked on the pipe or male end of the fitting using a felt-tip marker. The correct insertion depth is shown on the table below. Only correctly mounted fittings guarantee full pull-out force, as the crimp produces the strength behind the seal ring‘s bead. Minimum spacing (also shown on the table below) must be maintained when fittings are placed one directly after another.

ADimensions in mm Insertion depth in mm Spacing between fittings in mm 15.0 20.0 10.0 18.0 20.0 10.0 22.0 21.0 10.0 28.0 23.0 10.0 35.0 26.0 10.0 42.0 30.0 20.0 54.0 35.0 20.0 76.1 53.0 20.0 88.9 60.0 20.0 108.0 75.0 20.0

Verification

Verify the seal ring is present before slipping on the fittings. Furthermore, any foreign particles in the vicinity of the crimping site or on the seal ring must be removed.

62

Slipping on the fittings

The fittings are slipped on by means of gentle rotation and pressure toward the pipe axis until the marked insertion depth. In the case of sliding sleeves, the marked insertion depth must be reached at minimum. The fitting must be kept straight when slipped on. The seal ring may be damaged if the fitting or pipe is tilted.

Due to the matched tolerances, simplesta® system pipes are always the correct size for the fitting. Suds or water can be used as a lubricant to improve the antifriction properties. Oil or grease may not be used as a lubricant (we recommend: Bechen Berulub Sihaf 2). Pipes or prefabricated structu-ral elements should be aligned before crimping. Piping components may be moved (e.g. raised) after crimping. If straightening is necessary, no load must be placed on the press fitting‘s coupling (also applies to couplings that have already been crimped). Threaded and flanged couplings should be sealed and positioned prior to crimping. This prevents inadmissible loads on the crimp sites.

Post-verification

After crimping, it is necessary to verify whether the marked insertion depth is still given. The coupling must be renewed in the event of any deviation from the specifications.

Crimping 15 to 54 mm

Please note: Detailed information on operation is availablein the operating instructions supplied with each device. We strongly recommend that you read the specific instructions, including those of the pressing jaws and pressing collars with adaptor jaws, carefully before using for the first time.

Dimensions 15 to 35 mmPressing jaws are used for these dimensions. The pressingjaw that fits the dimensions to be crimped is mounted onthe device and secured with the retaining pin.

The pressing jaw is placed around the press fitting bead. The pressing device’s start button is then pressed and the pressing jaw closed completely. Since the pressing device has a built-in forced return, the pressing operation cannotbe interrupted before the final force is reached.

Dimensions 42 and 54 mmPressing collars are used for these dimensions. A ZB 203

adaptor jaw is used for the two pressing collars and insertedinto the power unit then secured with the retainingpin.

The pressing collar with the right dimensions for the fittingis then placed over the press fitting bead and closed.

The ZB 203 adaptor collar is now opened using manual pressure and hooked into the pressing collar. Pressure is then applied until the press fitting tool switches off.

All metallic materials expand when heated and contract when cooled. The thermal coefficient of linear expansion (α) for stainless steel with the material number 1.4401 in the temperature range 200°C and below is 0.0000165 m/mK.

Accordingly, the linear expansion is calculatedas follows:Io = length before heating It = length after heating ∆t = temperature difference between initial and final temperature (K)

α = coefficient of linear expansion

Example: It = Io x (1 + α ·∆t)

Pipe attachment and installation

Length variations during operation must be consideredwhen the piping is installed. This means the establish-ment of expansion chambers and possibly expansion compensators. Fixed and floating points must be set correctly.

It is possible to balance out small length variations through the existing expansion chamber and elasticity

of the pipework. If this is not possible in larger pipeworksystems or for any other reasons, then expansion com-pensators must be used. Examples here are pipe arm or U-bend expansion compensators.

If the piping is installed in front of a wall or in installationshafts, the expansion is usually large enough for the implementation of compensatory measures.

If the piping is concealed, then it is essential to place itinside an elastic padding, such as mineral wool or in aclosed-cell insulation tube.

With regard to piping installed in the impact sound insulation beneath screed, it is important to pay atten-

tion to outlets/wall breakthroughs and the screed itself. This must be padded as appropriate with insulating material. This generally applies to other wall or floor breakthroughs, too.

One anomaly is the enclosure of piping beneath masticasphalt screed, where the exposure to heat may damage the seal ring. For this reason, the piping has to be cooled down with cold running water. In addition, the entire piping must be protected with suitable insulation.

Pipe attachments that support pipework and for the deflec-tion of temperature-induced length variations are imple-mented as fixed points (pipe and fitting are permanentlyconnected) and floating points (pipe and fitting are both able to move axially). It is essential to ensure that the pipe attachments are suitable for use with stainless steel.

No mounting hardware may be attached to the press fittings.

*Connecting pipes must be long enough to absorb

any possible linear expansion in the piping system..

With regard to long pipe sections, we recommend the placement of only one fixed point in the middle of the section for linear expansion in both directions. This only subjects the branches to about half the load as opposed to a fixed point at the end of the piping.

This use case is typical when riser pipes cover several floors. Floating pointsFixed point

SoundproofingPiping does not represent an additional source of noise. However, it carries noise caused by appliances and other fittings and therefore has to be soundproofed when in-stalled. When installed as per the norm, the sound pres-sure level in drinking water installations must not exceed 30 dB(A). The increased sound insulation in residential construction requires 27 dB(A) and the comfort sound

insulation 24 dB(A). Compliance with these requirements in all parts of an installation can only be guaranteed with extensive knowledge. It is advisable to consult an acoustical engineer during the planning phase.

Fire protectionThe pipes and fittings in the simplesta® ST stainless steel piping system are non-flammable. However, the relevant provisions must be observed for installation in the vari-ous building types. The requirements for pipe systems in buildings are laid down in Germany‘s prototype building regulation, federal state building regulations, and spe-cial building regulations. Depending on federal state, the design details are laid down in implementing regu-lations, administrative provisions or technical building regulations. Special requirements for technical building service pipe systems are laid down in Germany‘s guide-line on pipe systems (MLAR/LAR/RbALei3), as amended. The MLAR/LAR/RbALei3 has been implemented in all the federal states within the framework of the technical building regulations.

Wall and ceiling ducts

Single non-flammable piping without insulation insideits own breakthrough/hole: The piping may be concealed in mortar. The spacing to the next piping must corres-pond to the diameter of the largest pipe.

An annular space of up to 15 mm may be closed with fo-aming material. An annular space of up to 50 mm may beclosed using mineral wool with a melting point and density of at least 1000°C and 120 kg/m3 respectively. Single non-flammable piping without insulation in shared breakthroughs: The pipes are installed side by side at a distance of at least the diameter of the largestpipe and concealed in mortar.

Single piping with insulation in shared breakthroughs or its own hole: Mineral wool (see above) may be usedfor insulating the duct. If non-flammable lagging (A1 or A2) is also used, then the spacing between piping can be reduced to 0 mm.

Heat emission and insulationIn addition to conveying fluids, piping also emits heat when the ambient temperature is different to that of the fluid – it practically acts as a heating device. The same applies vice versa. When the ambient temperature is hig-her, the piping absorbs heat and cools the surrounding environment. This can be used for underfloor heating, electric blankets, heating panels, and concrete core cooling. Unintended heat transfer has to be minimised by suitable insulation, however. This is provided for by applicable standards and regulations: DIN 1988, DIN 4108, DIN EN 14303 and Germany‘s regulation on energy saving.

Low-temperature piping also needs to be insulated to prevent condensation and it being heated by high-temperature piping (see Hygiene).

Please note that the concentration of chloride ions in any material used for thermal insulation should be as low as possible. DIN 1988 states a value of no more than 0.05% for water soluble chloride ions. We recommend AS grade insulants as defined by DIN EN 13468 and AGI-Q 132, which are significantly less than this value. The use of felt is not allowed, as this insulant absorbs moisture quickly. We recommend the use of closed-cell insulation tubes that do not absorb moisture.

*German regulation on water for human consumption

ApplicationsThe simplesta® ST stainless steel piping systemwith the EPDM seal ring is suitable for thefollowing types of water:

Continuous chlorination/disinfectionof drinking water

The simplesta® ST stainless steel piping system is suitablefor temporary continuous disinfection pursuant to Article 11 of Germany‘s regulation on drinking water, as amended. 1.2 mg/l of chlorine may be added to the disinfectant as free chlorine pursuant to Germany‘s regulation on drinking water. The tolerance limit in treated drinking water is 0.3 mg/l of free chlorine.

Up to 6 mg/l of chlorine may be used in the disinfectantas free chlorine in exceptional cases. The maximum to-lerance limit in treated drinking water is 0.6 mg/l. The simplesta® ST stainless steel piping system can be used without any complications if these tolerance limits are complied with.

Disinfecting the piping/basic disinfection

Different chemical substances can be used if piping systems need to undergo basic disinfection for variousreasons. The piping system may not be used for the supply of drinking water while such work is ongoing. If chlorine is used for disinfection, the concentration of free chlorine for 16 hours may not exceed 100 mg/l.

For 24 hours, no more than 50 mg/l is permissible. These concentrations and periods must be strictly compliedwith. Pitting corrosion may occur if the material is over-loaded, which may result in the need to overhaul the entire installation.

Therefore, and in the interest of environmental pro-tection and handling safety, we recommend the use ofhydrogen peroxide, in particular, or otherwise potassiumpermanganate.

The disinfecting action of potassium permanganate in alkaline media is low where the action of hydrogen peroxide is relatively unaffected by the concentration of hydrogen ions up to pH values of eight. Such mediaare approved only for system disinfection, not for addingto drinking water continuously.

For procedure, concentrations and periods, we recom-mend the DVGW‘s W 291 and W 557(A) worksheets.

Not only the process-based measures outlined in brief combat the contamination of an installation, planningand operational measures can also significantly reducethe bacterial count in drinking water systems. See the 'Hygiene' section for more information on the above.

Other media

The green FPM seal ring is used in the simplesta® ST stainless steel piping system for the media listedbelow:

Compressed-air systems class 6-10 Mineral oil, vegetable oil, light fuel oil Solar installations up to +180 °C Concrete core cooling General fuels*

*after consulting with the application technology department

The operating temperatures are between -20°C and +180°C (+200°C for short periods) and the maximum operating pressure is 16 bar.

These seal rings are purchased separately. The installingengineer then exchanges them with the black EPDM seal rings locally.

Notes on corrosion resistance

Internal corrosion

The austenitic and ferritic steel made using the material 1.4401, 1.4404, 1.4521 or 1.4408 (press fitting parts, e.g. threaded pieces), which is used for the simplesta® ST stain-less steel piping system, is suitable for any type of water pursuant to Germany‘s regulation on drinking water, as amended, without any restrictions, i.e. hygienically safe and corrosion resistant. Furthermore, it is non-active in drinking water and there are no problems with heavy-metal contamination. Needless to say, the materials are suitable for softened and desalinated water.

There must be no formation of increased halogen concen-trations, e.g. due to seals that release chloride into water or lead to a local concentration of chlorides. Chloride-free hemp or plastic sealing tape that does not release halogens should be used for sealing threaded transitions. EPDM tape (Teflon tape) must not be used. Furthermore, there must be no external or internal heat transfers for the same reason. Deposits could form on the inside, causing a localised increase in chloride concentration and pitting corrosion.

The use of trace heating is limited to 60°C maximum. Non-recurring heating to 70°C for no longer than one hour is permitted at 24-hour intervals for thermal disinfec-tion, however.

The piping must be kept full at all times to prevent the

three-phase boundary of water/material/air. This instruction corresponds with DIN 50930 and applies for all metallic pipes to prevent corrosion damage.

In particular, this must be considered after pressure testing or if the water pipe has to be fully or partly emptied. We recommend a pressure test with air for reasons of hygiene alone (see Hygiene) if the piping is emptied again after pressure testing or there is a possibility that water will evaporate from openings in the installation.

External corrosion

External corrosion may occur if stainless steel piping is exposed to building materials or insulants that are moist and contain halogens or if moisture forms on the piping permanently and evaporates there. High-temperature pi-ping is particularly affected. A concentration of halogens could form there, causing pitting. Moreover, the piping must not be exposed to chlorine gases, salt water or other waters containing high levels of chloride.

The pipes should be given a coating that is resistant to heat, non-ageing and, most importantly, permanently waterproof if stresses of this nature are unavoidable. Plastic binders as per DIN 30672 or closed-cell insulationtubes with seams that are permanently sealed and waterproof can also be used. The insulant itself must not

release any chloride ions, either. DIN EN 13468 and AGI-Q 132 AS grade insulants are suitable. If the conditions in the building materials in which the pipes and components are installed are such that moisture and the inclusion of halogens cannot be ruled out over an extended period of time, then a surface- mounted installation should be considered.

Additional notes on corrosion resistance

The simplesta® ST stainless steel piping system is suitable for all mixed installations without limitation. Different materials can be connected to the stainless steel in any order (no flow rule).

There is no risk of contact or bimetallic corrosion when stainless steel and non-ferrous metals (brass, copper, red brass) are assembled with one another directly.

In mixed installations comprising stainless steel and hot-dip galvanised ferrous materials, contact corrosion can occur on the latter material.

The installation of a component or shut-off valve made of non-ferrous metal ≥50 mm between the stainless steel and hot-dip galvanised steel prevents the spread of any contact or bimetallic corrosion.

Hot bending techniques may not be used on stainless steel pipes, as heat tinting forms and the structure sensitises critically after prolonged heat exposure, each of which reduces corrosion resistance and may result in leakage.

The pipes must not be cut by means of grinder, burning or plasma torch (see 'Cutting and deburring'). The pipes and fittings must be stored and machined such that no foreign materials, e.g. normal steel particles, sparks from grinders or building materials containing chloride (setting accelerator), are able to settle on or inside them.Stainless steel pipes may not be soldered or brazed, as they may be prone to knife-line attack when the corre-sponding temperatures are too high. Knife-line attack has also been observed even in the case of soldering or brazing techniques regarded as suitable.

Stainless steel pipes may not be welded on site becauseall the necessary conditions for reliable welded joints, such as making the weld site and heat-affected zone completely inert, are generally not given.

Pressure loss

The flow of any fluid within pipework is affected by friction and various single resistances. Friction in this case refers primarily to internal friction (particles withinthe fluid rubbing together) and the friction of the fluid on the wall of the pipe.

Single resistances consist mainly of the preforms withinthe pipework, such as bends, tees, and reducers. The loss of pressure in water meters, filters and other such appliances is not recorded as a single resistance but se-parately depending on peak flow. Pressure loss is then determined according to set values or pressure loss curves from the manufacturer.

For any questions regarding methods of calculation and associated formulas, we recommend the relevant

standards and such technical literature as 'SanitärtechnikBand 1 und 2' (sanitation installations volumes 1 & 2 – publ. in German, Krammer Verlag Düsseldorf publishinghouse) by Hugo Feurich.
