NON-ANODIC CONNECTING PIPE WITH DETECTING WIRE

摘要

The invention relates to a non-anodic connecting pipe with detecting wire, used for branching the consumers to the natural gas distribution systems, said connecting pipe consisting of polyethylene pipes. According to the invention, the connecting pipe comprises a high density polyethylene pipe (1) joined by electro-fusion with an electric fitting (4) on which a connecting valve (11) is mounted, said elements being accommodated in a metal tube (5) provided with some spacing rings (3) which secure the assembly inside the tube at both ends, and to the outer side the tube (5) is protected with an anticorrosive polymer insulation (6) provided with an electric detecting wire (7) accompanying the pipe on its whole length and at the end is inserted in an electric terminal (8).
