The ends of two double pipes (1), each with an inner (3) and outer (2) pipe, are joined by a protective plate (8) between the outer and inner pipes. Connected to the edge of the plate located against the inner pipe is a female-type outer connection (10) for joining the plate to the outer pipe. Tracks outside the inner connection (9) and the outer connection serve to fasten the plate and seals. In the track (13) outside the outer connection (10) is connected a fixture fillet (6) which in conjunction with a clamp fillet (7) fastens the two double pipes axially. |
