Angular rubber expansion joints

Structure: Rubber bellows with tie bar and flanges.  

Movement absorption: Angular movements of the expansion joint are absorbed. The angular joints regulate a defined angular movement, absorb axial stresses and relieve the load on the pipeline fixed points. A distinction is made between hinged angular expansion joints (angular movement of the bellows is diverted on one level) and cardan-joint angular expansion joints (angular movement of the bellows is diverted on two levels).  

Fixed points: Only light fixed points are required to absorb angular displacement and friction forces.
