Gimbal Expansion Joints have a single bellows and a unique pressure thrust resisting structure which permits angular movements in any plane.

The structure contains two hinge mechanisms which allows simultaneous rotation about two perpendicular axis which intersect at the centre line of thebellows.

Pressure Balanced Expansion Joints are devices which produce no pressure thrust forces in the piping system on the main anchors. In addition to eliminating the pressure thrust,

The expansion joint can accept axial compression, axial extension, lateral and angular movements. The balancing thrust is created by using a balancing bellows.
