Title: Connection method for polyethylene pipe for supply water
Inventor: KITAGAWA MASAYOSHI
IPC: B29C65/00
Filed: 1991-06-17
Abstract: PURPOSE:To perfectly weld a polyethylene pipe, especially suitable for a pipeline for supply water to a polyethylene pipe coupling without fail. CONSTITUTION:A low density polyethylene pipe 2 for supply water is inserted in the inner surface of a high density polyethylene pipe coupling 1 for supply water. Further, a core tool 3 adhered on the inner surface of a pipe is engaged throughout the length of a weld part. Through energization of a heating wire 4 embedded in the weld surface of the pipe coupling, slight surplus welding is effected. Thermal expansion generated by heating is constrained between a high strength of the outer surface side and the core tool on the inner surface side and converted into reaction which strongly presses a contact surface. Thus, a dense and complete weld part is provided. Fine management of a work is eliminated. A piping work at a site is carried out without an individual difference and failure.
