Summary

A single expansion joint is designed to permit angular rotation in any plane by the use of two pairs of hinges affixed to a common floating gimbal ring.

Unlike the hinged joint, which can absorb angular rotation in a single plane only, the gimbal joint can absorb angular rotation in any plane. The ability of the gimbal expansion joint to absorb angular rotation in any plane is most often applied by using two gimbal joints which act together to absorb movement. Gimbals, like hinges, are designed to transmit the pressure thrust and are used in pairs, or in conjunction with a hinged joint. A gimbal ring is either round or square. For round gimbals the torsional moment shall be considered and for square gimbals the instability due to the bending shall be considered.

Features

· Absorbs angular rotation and low forces on piping system
· Withstand pressure thrust load and no main anchors required
· Transmits shear loads and prevents torsion on bellows

Types of Movement

· Angular rotation in any plane

Summary

Double gimbal expansion joint is designed to absorb lateral and angular movements in any direction. This model is made up of two bellows joined together by a linking pipe and a double universal connection system. The benefit of having these expansion joints are to absorb pressure thrust in the system.

A double gimbal expansion joint is basically a two single gimbal expansion joints and an intermediate pipe that joins them. This type of expansion joint can absorb a large lateral movement in any plane and angular movement in any direction. Double gimbal expansion joints are being designed and produced based on customer needs.
