Repair of major damage is done by so-called repair linings. Their distinguishing feature include the following: the presence of a welded zone, not only on the surface, adjacent to the tube, but also on the lateral shoulder. Thus, it is possible to repair damage from extended areas, restoring the old pipeline performance (in particular, the full working pressure), because this design makes it possible to weld together an arbitrarily large amount of overlap.
Installation is carried out in the application of welding technology of saddle parts. Preliminary pressing of repair clamps are using special clamping devices or devices of its own making.
If the damaged PEX pipe beyond the central zone of the cold saddle component or weld zone overlaps the location of damage, you must close the gap between the pipe and the surface of the saddle element of PEX material, such as using hand-held extruder.
Thus, polyethylene piping is well proven in the field of plumbing and gas supply. Despite the excellent performance of the PEX network, completely avoid the production of damage is impossible. Presented in this article possible repair of networks of PEX by means of mechanical fittings or parts of mortgages PEX radiant heating element offers a technically elegant and cost-effective alternative to traditionally used technology repair.
