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.
