Net forming a resistance, its application to the welding of tubes edge and to the transverse connection of pipe, the assemblies thus constituted and branch offtake electrofusion thus equiped.

摘要

This is an electrically conductive heating net which is adapted to form a resistance and which is substantially in the shape of a collar (30) defining, by construction, a central orifice (35). The net may comprise one or more single- or multi-strand wires (31). Application in particular to the thermal butt-welding of tubes or of pipelines and of tap-offs, made of plastic. IMAGE
