Gimbal Expansion Joints

The gimbal expansion joint is the most reliable expansion joint since it is capable of absorbing angular motion in all the planes. Although single gimbal bellows joint can be used in isolation the most common applications use a pair of gimbal bellows joints to absorb a complex multi-plane motion in a piping system. In adjacent figure Gimbal Expansion Joints are utilized in a pair to absorb the thermal expansion from the two horizontal piping arms. However note that the thermal growth of the vertical.

To avoid this deflection in the horizontal piping arms one or more hinged expansion joints can be installed in the horizontal arms of the piping system.
