摘要

Two composite pipes (20) with a metal core (26) between synthetic outer (24) and inner (22) layers are joined by welding into a junction sleeve (10). The pipes (20) fit into sections (14) equipped with resistance heating elements (32). Each section (14) has an interior abutment surface (18) formed on the interior of the junction sleeve (10). The resistance heating element (36) of each section has a further part (38) in the vicinity of the abutment surface (18).
