Inline Pressure Balanced Expansion Joints
Features
The two bellows of expansion joint has an intermediate balancing bellow with a large diameter. The balancing bellow and associated components may absorb the internal pressure thrust. Thus it can constrain the pipes’ thrust. Generally it is applicable to straight pipeline segments where it is impossible to set up a main fixed support, and it is to absorb axial displacement only.
