ABSTRACT In a pipe coupling according to the invention through material sele- ction the outer sleeve is optimized with respect to linear and radial strength and positive connection and the inner portion or liner of the pipe with respect to chemical inertness and the tightness of the connection The design of the pipe and coupling part is optimized with respect to a material-correct joining procedure. The compound pipes 1 comprise a rigid, relatively thin pipe outer sleeve 3 for absorbing and transferring forces and a softer, relat- ively thin liner or inner pipe 4 for the tight connection and inert sealing with respect to the rigid outer wall. Like the pipe, the coupling part 2 is made from a rigid joining outer sleeve 5 and a weldable socket 10, preferably from the same material as the liner 1. The welding energy is preferably introduced electrically. In order to bring about a frictional connection on the one hand and a tight connection on the other between the two pipes, it is necess- ary for the inner pipe or liner to protect by approximately half the length of the socket 10 at the joining point in the form of a free pipe end 9, which in the assembled state comes to rest in the electrically weldable socket 10 and that on the outer sleeve and on both sides of the joining part 2 is shaped a socket-like portion 6, so that following the introduction of the pipes into the coupling part 2 it embraces the corresponding areas of the pipe outer sleeve. The free pipe ends 9 are welded in full-circum- ference manner in the vicinity of the filament winding 12 and the coupling outer sleeve 5 is bonded frictionally to the pipe outer sleeve 3 in the vicinity of the socket-like portion 6. The logical separation of the frictional and sealing connection into a simultan- eous, but independently optimizable procedure, without any reciprocal negative influencing and whilst retaining the advantages of both, leads to a hitherto unachieved result.
