PIPE FITTING
This invention concerns a pipe fitting which consists of a press fitting of corrosion-resistant material which has at least one section extending outwards or inwards and having a seal ring and a cylindrical area adjacent to it. This cylindrical area has a crease at the end of the extension and has a line pipe out of corrosion-resistant material, the end of which can be pushed into or onto the press fitting up to the mating edge. To that effect, the thin-walled line pipe (5) has a tightly fitting non-metallic jacket (7) shape-mated with it which, together with the line pipe (5), forms a compound pipe and the end area of the line pipe (5) has a supporting bushing (9, 11, 18).
