PE/PP Compen­sators

Defined compensation for length changes in the piping system

Reinert-Ritz compen­sators for absorbing axial movements in piping systems are manufac­tured from homoge­neously extruded half-finished materials. They are charac­terised by high tensile strength and a plastic compatible design. They are built to resist tensile forces in accor­dance with ISO 3501. These fittings can be also be subse­quently integrated into a piping system via the HP flange connection. The seal system consists of the tried-and-tested, drinking water quality EPDM lip seal. An integrated clamp seat as fixation for a compen­sator side enables the defined axial movement to be limited to one side.

PE100 compensator, anchor point type, longitudinally force-locked in accordance with ISO 3501

General preliminary remark

The fittings to be offered must be manufactured from material in compliance with the PE100+ Association and according to DIN EN 12201 with respect to dimensions, tolerances and quality requirements. Proof must be provided that they were manufactured on the basis of a quality assurance system in accordance with DIN EN ISO 9001. For all fittings a certificate in accordance with DIN EN 10204 must be submitted by the manufacturer. The body of the fitting must be manufactured in the injection moulding process or alternatively, in the case of more complex structures, from a piece of homogeneous semi-finished material so as to ensure the required reinforcement and therefore high stability of the fitting. Semi-finished materials manufactured from wound rods or the subsequent application of other forms of reinforcing are not permitted.

The fitting must be pressure class-compatible and longitudinally force-locked as a whole. The flange connections must be pressure class-compatible and the hole pattern must comply with DIN EN 1092-1 PN 10 or PN 16. Depending on the mating flange type, the flange connection must be implemented as an HP flange or a special flange of the same nominal diameter.

The backing flanges must be manufactured from corrosion-free, fibre-reinforced plastic or from steel with a plastic coating in accordance with DIN EN 10310.

The sealing function must be provided by a system 3S lip seal that allows axial movements of the pipe and is manufactured from an elastomer material appropriate to the medium. EPDM lip seals must be used for drinking water applications and NBR seals for waste water applications.

The maximum elongation value of the compensator must be indicated.

The fixing clamp must not exert any radial force on the body of the socket.

Compensators are designed for aboveground use in pressure pipelines. Installation in underground pipeline construction is only possible under certain conditions.

Optionally available:versions: without anchor point clamp seat, stainless steel backing flange, galvanised backing flange, flat sealing without groove and O-ring or with long holes in the PE stub for perfect alignment of the accessories to be connected.
