Piping system of the installation and repair of the method and apparatus

摘要

The invention relates to a method of joining or repairing piping system (1) comprising at least two pipes (2) made of a weldable plastics material, the sleeve consisting of weldable plastics material (5 ) comprising the sleeve (5) of the length a is greater than the distance B between opposing pipe (2) to each other, each pipe end (2a, 2b) and so as to overlap a predetermined range C, between the two pipes a method comprising a step of fitting the sleeve to the distance. The method has two ends (6a, 6 b) placing electrically conductive band (6) on one periphery of the inner pipe (2) having a band end portion (6a, 6 b) as to overlap each other by placing a step of connecting the band end portion (6a, 6 b), the pipe (2) a step of fitting the sleeve (5) and over the band (6) and against them predetermined time, current is applied band (6), whereby the time determined a band (6) is heated to-determined temperature, is placed adjacent band (6) in the pipe (2) and the pipe dissolved together with the plastic surface of the sleeve (5), comprising the step of forming the inner and welded junction sufficiently performed pipes surrounding (2) and the sleeve (5). The present invention further relates to apparatus for use when working according to this method (12)FIELD 1
