Gimbal Expansion Joint

A Gimbal Expansion Joint can absorb angular deflection in any plane. It consists of two pairs of hinges connected to a common floating ring. Gimbal Expansion joint can consist of a single bellow, where there is no lateral deflection, or two bellows connected by a common connector where it can permit a lateral deflection also. The pairs of hinges, gimbal pin and the gimbal floating rings should be designed to restrain the pressure thrust.Advantages: Permits angular movement in any plane. Gimbal pins are designed to withstand the pressure thrust, so the load on the anchors is reduced. Prevent torsional movement of expansion joint as the two pairs of the hinge pins are connected to the gimbal ring. Reduced forces on the piping system and main anchors. Resists extraneous forces created form wind loads, piping loads, dead weight of the machinery, etc.
