Method and apparatus for installation and repair of piping system

摘要

A method for joining or repairing a pipe system that comprises a least two pipes made of weldable plastic material, comprising: fitting a sleeve made of weldable plastic material the distance between the two pipes, the sleeve having a length A that exceeds the distance B between the mutually opposing pipes, such as to overlap each pipe end to a given extent C; placing an electrically conductive band around one of the pipes, the band having two ends; connecting the band ends to each other by placing the band ends overlapping each other; fitting the sleeve over and against the pipe and the band, and applying an electric current to the band over a given period of time, thereby heating the band to a determined temperature for a determined time and fusing the band with the plastic surfaces of the pipe and the sleeve lying in abutment therewith to form a welding joint being fully executed around the pipe and inside the sleeve.
