Pipe system for sanitary and heating systems, entirely or predominantly made of plastic.

摘要

A pipe system for sanitary and heating systems, which consists entirely or predominantly of plastic, in particular polypropylene, and serves for providing water, is equipped with a welding device for welding together parallel plastic pipes, with which an end-side length adjustment of the plastic pipes can be brought about, and which has a rider body (3), which can be mounted on the plastic pipes (1, 2) which are arranged parallel to one another, with a stirrup body (4) which in its mounted position can be pivoted downwards over the pipe ends (5, 6) transversely to the longitudinal axis of the pipes and has an end plate (7), against which the end sides of the pipe ends come into contact.
