different types of expansion joints
GIMBAL EXPANSION JOINT. A gimbal Expansion joint is an assembly designed to absorb angular movement in any plane. The gimbal hardware consists of two sets of hinges, connected to a common floating gimbal ring, which is designed to absorb the pressure thrust of the Expansion joint assembly.
A Universal Expansion joint is an assembly containing two bellows connected by a centre pipe and equipped with tie rods. Universal Expansion joints are mainly used to absorb any combination of the three basic movements in the piping system. (Axial, Lateral, Angular).
A Hinged Expansion joint is an assembly designed to absorb angular rotation in the plane perpendicular to the hinge pins. The hardware consists of two hinged plates 180 Â° apart and joined to the end connection.
A pressure balanced Single or Universal Expansion joint is an assembly designed to absorb axial movement and /or lateral deflection while the pressure thrust is balanced by means of an additional bellows and tie rods.
