Abstract

Changes in length of a district heating pipeline which arise as a result of temperature changes are absorbed by inserting axial compensators, said compensators being provided with a flexible metal bellows (1) secured in a gas-tight manner to each its tube piece (3, 4) inside the compensator. The variations in length which arise are taken up by the metal bellows. This construction ensures a completely closed compensator, thus preventing the ingress of water, steam and foreign matter between the tube ends, and thereby ensuring undisturbed operation of the bellows. By forming the tubes (3, 4) in such a way that they act as a telescopic guide, optimum stiffness and thus protection of the bellows is achieved. The bellows (1) is protected externally by a casing consisting of a cylinder (10) which extends between two flanges (7, 8), thus totally enclosing the bellows. Furthermore, the compensator can be provided with a pair of rails (9) having a sliding engagement with recesses in a guide (11), this guide being secured to the casing cylinder (10). This prevents torsion of the bellows during installation work, when the compensator is twisted to provide access for welding between the compensator and the district heating pipeline.
