EXPANSION JOINTS

In some district heating pipelines, the movements are very large and therefore calling for customised district heating expansion joints. Belman are experienced in the design and manufacture of customised solutions – also for district heating expansion joints. In this special case, the owners of an Eastern European district heating pipeline profited directly from our expertise.

Special design to absorb large movements
The expansion joints had to absorb +0/-300 mm axial movements, a very large movement for a DN 150 pipe. For this reason, a special solution was required, the optimum result being a double expansion joint, comprised of two standard district heating expansion joints. These two were mounted opposite each other making the absorption of the large movements possible. This resulted in a build-in length of 1460 mm. To absorb these large pipe expansions (-300 mm) the expansion joints were also pre-stressed.
