District Heating Expansion Joints

Ayvaz’s highly flexible metal bellowed expansion joints are designed to absorb large axial movements specially for installation in district heating pipe systems.

The highly flexible bellow of the compensator ensures absorption of large axial movements. The cover, guides and rings of the compensator contribute high stability. The cover likewise absorbs eventual misalignments in the pipeline, which can occur if the pipeline hangs a bit in the compensator.
