TYPES OF EXPANSION JOINTS
1
EXPANSION JOINT
 
Mainly single expansion joint is designed to absorb axial & small amount of lateral & angular movements of the piping system in which it is installed. A DOUBLE expansion joint is consist of two or more bellows joined by common connectors
 
 
2 UNIVERSAL EXPANSION JOINT
 
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)
 
 
3 PRESSURE BALANCED EXPANSION JOINT
 
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. This type of Expansion joint can usually be used only where change of direction occurs in the piping system .
 
4 HINGED EXPANSION JOINT
 
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 ° apart and joined to the end connection. The hinged hardware is designed to absorb the pressure thrust of the Expansion joint assembly. A pair of Hinged Expansion Joints shall absorb lateral deflection.
 
5 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.
