Abstract
A double-walled pipe which is corrugated in the form of a helical line is connected to a double-walled rigid pipe or pipe connecting stub. The metallic inner pipes (10, 20), which carry hot or cold media, and the outer pipes (22, 30), which consist of plastic or Eternit are held coaxially, and the annular cavity located between the pipes is filled with insulation material (48). A supporting bush (34) consisting of a material which is mechanically stable up to temperatures of at least 200 DEG C and is thermally and electrically insulating forms the holder of the pipe connection. The suitably shaped outside of the supporting bush (34) is screwed into the outer pipe (30), which is corrugated in the form of a helical line, and engages with the bearing surface (40) of the supporting ring (14) in the direction of the rigid inner pipe (10), along the entire circumference of a coaxial recess. An opposing bearing (abutment) (42) prevents the welded inner pipes moving apart from one another axially. <IMAGE>
