In the case of a fixing point for prestressing remote-heating lines, two rows of ribs (2, 3) are welded onto the medium pipe (1). Annular flanges (4, 5) are welded onto the ribs, which annular flanges (4, 5) clamp a metal ring (13) in between them. The metal ring (13) has an annular groove (14) into which a clamping ring (15) is inserted which, in the prestressed state of the pipeline, is supported in a groove (21) in the outer pipe (19, 20) (Fig. 1). <IMAGE> |
