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

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 requirements. 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).

Esta Rohr has the experience and production number 1.4401 and ferritic stainless steel with the material techniques needed to process the material properly. 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, molybdenum improves the pitting resistance of 1.4401 and 1.4521 by 2.0 to 2.5%.

Finally, any swarf must be removed from the swarf from inside the pipe. Steel brushes may not pipe‘s inner surface (so that no swarf becomes caught be used between seal ring and pipe) and outer surface (so that as few particles as possible enter the pipe system during installation).

60 INSTALLATION

Marking the insertion depth

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.

61 Slipping on the fittings

The fittings are slipped on by means of gentle rotation and Post-verification pressure toward the pipe axis until the marked insertion depth. In the case of sliding sleeves, the marked insertion After crimping, it is necessary to verify whether the marked depth must be reached at minimum. The fitting must be kept insertion depth is still given. The coupling must be renewed straight when slipped on. The seal ring may be damaged if in the event of any deviation from the specifications. 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.

62 INSTALLATION

Crimping 15 to 54 mm

Please note: Detailed information on operation is available in 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 mm Pressing jaws are used for these dimensions. The pressing jaw that fits the dimensions to be crimped is mounted on the 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 cannot be interrupted before the final force is reached.

Dimensions 42 and 54 mm Pressing collars are used for these dimensions. A ZB 203 adaptor jaw is used for the two pressing collars and inserted into the power unit then secured with the retaining pin.

The pressing collar with the right dimensions for the fitting is 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.

63 Crimping 76.1 to 108 mm

Dimensions 76.1 and 88.9 mm Pressing collars are used for these dimensions. A ZB 221 adaptor jaw is used for the two pressing collars and inserted into the power unit then secured with the retaining pin.

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

The ZB 221 adaptor collar is now opened using manual pressure and hooked into the pressing collar. Pressure is then applied until the power unit switches off.

Dimension 108 mm An appropriate pressing collar and adaptor jaw are also used for these dimensions. However, this involves two processes and two adaptor jaws. To begin with, the ZB 221 adaptor jaw (also used for 76.1 and 88.9 mm) is inserted into the press fitting tool and secured using the locking pin.

64 INSTALLATION

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

The ZB 221 adaptor collar is now opened using manual pressure and hooked into the pressing collar. Pressure is then applied until the power unit switches off.

The adaptor jaw is unhooked and removed from the power unit. The 108 pressing collar remains firmly on the fitting and cannot be removed. The ZB 222 adaptor jaw is then inserted into the power unit and secured with the retaining pin.

The ZB 222 adaptor jaw is now hooked into the pressing collar and pressure applied again until the power unit switches off. The adaptor jaw is then unhooked. The pressing collar can now also be removed without much effort.

All metallic materials expand Io = 15000 mm when heated and contract when cooled.

Pipe attachments that support pipework and for the deflec- tion of temperature-induced length variations are implemented as fixed points (pipe and fitting are permanently connected) 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. Elastic Floor padding No mounting hardware may be attached to the press fittings.

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.

Their proliferation optimum is only in the temperature range 25-45°C. The pathogenic properties emerge if concentrations are high enough. It is beyond doubt that there are fatalities every year in Germany due to heated drinking water. With that in mind, it is advisable to plan, assemble, and operate domestic drinking water installations appropriately.

Flushing

Piping is flushed prior to commissioning according to DIN 1988 and DIN EN 806. The ZVSHK has summarised the only possible methods of flushing and thermal disinfection in its fact sheet 'Spülen, Desinfektion und Inbetriebnahme von Trinkwasser-Installationen' (washing, disinfection and commissioning of drinking water installations – publ. in German) issued in 2014. This fact sheet also contains templates for flushing log, disinfection log, commissioning and briefing log for drinking water installations.
