Angular expansion joints

Angular expansion joints are suited for the compensation of both long pipe sections of district heating systems as well as short boiler and turbine room pipelines in one or more planes.

For installations with very limited space one should also check the possibility of the installation of tied universal or pressure balanced expansion joints.

Contrary to axial and universal expansion joints that are suited to compensate for movements independently, angular expansion joints are only elements of an expansion system.

Angular expansion joints are usually installed with 50% pre-stressing. This is accomplished by pre-stressing the entire expansion system after its completion. The pre-stressing amount can be determined taking into account the installation temperature.
