Joining and expansion sockets with anchor point
The detachable push-fit coupler for absorption of axial movements in the pipe string
For non-underground pipe systems Reinert-Ritz offers, with the joining and expansion socket and the double joining socket, detachable push-fit couplers that are fully pressure-resistant thanks to the EPDM lip seal and are even designed for negative pressure. These fittings are manufactured as standard with an anchor point for the fixing of the pipe string. Optionally the clamp fitting can be omitted and/or the lip seal selected as an NBR variant. Transitions to pipes of other materials such as PVC and of the same size are thus possible.
PE100 joining and expansion socket, anchor point type
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 as a whole. The spigot must be designed for HE butt welding process and correspond to the pipe dimension.
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 pipe in the joining and expansion socket must be indicated. For calculation of the elongation value, the possible incursion of the front end of the pipe must be taken into account. If necessary, countermeasures such as pipe stiffeners, for example, are to be considered.
The fixing clamp must not exert any radial force on the body of the socket.
Joining and expansion sockets 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, design according to DIN EN 1092-1 PN 25, 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.
