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. A minimum of two and a maximum of three angular expansion joints form a static defined system. The function depends on the ability of the bellows to rotate and the amount of rotation is stated in the technical data sheets as permissible angular rotation. Angular expansion joints are usually installed with 50% pre-stressing. This is accomplished by pre-stressing the entire expansion system after its completion.
