发明名称 PROCESS FOR PRODUCING A PIPE FITTING CONSISTING OF THERMALLY WELDABLE MATERIAL
摘要 To produce a pipe fitting applicable to pipes by welding, a heating wire is laid in the region of the contact surfaces and connected at the end to contacts. The pipe fitting consists of thermally weldable material in which both the heating wire and the contacts are secured by an injection moulding process. For a fast and reliable welded bond, it is proposed to arrange the heating wire at least in sections in a plane corrugated form, thus producing a corrugated heating strand. This heating strand is then arranged in windings in the desired welded regions of the pipe fitting. Here, the broad side of the corrugated line lies on the contact surface of the pipe fitting.
