1. Axial compensator for inserting in a pipeline, such as a long distance heating line, with at least one metal bellows, whose ends are in each case connected to a pipe section, the facing ends of the pipe sections having axially reciprocally displaceable, interengaging shape constructions with in each case at least three shape attachments arranged over the circumference of the pipe section and shape recesses arranged between adjacent shape attachments, characterized in that the shape attachments (18, 19) are T-shaped and with the same are associated T-shaped shape recesses (21, 22), that the depth defined by the T-cross beams of the shape recesses (21, 22) is more than twice as large as the height of the T-cross beam (23, 26) of the particular shape attachment (18, 19) and that cooperating shape attachments (18, 19) and shape recesses (21, 22) reciprocally engage behind one another and the shape attachments (18, 19) transferring the forces which occur directly from one pipe section (2 or 3) to the other (3 or 2) are constructed in one piece therewith. |
