Universal Hinge Expansion Joint

A universal hinge expansion joint consist of a universal bellow with two pairs of hinges. This type of expansion joint is used to accommodate large amount of lateral deflection in one plane. By providing a special arrangement of hinge box, the universal hinge expansion joint can also accommodate angular movement and lateral deflection in more than one plane.

  
Advantages

	Lateral motion in one/or more than one plane.
	Eliminates pressure thrust as it is restrained by the hinge pins.
	Prevents torsional movement of the expansion joint.
	Eliminates requirement of the main anchors.
	Requires minimum guiding supports.
	Reduces forces on the piping arrangement.
	Designed to restrain extraneous forces like wind loads, dead loads, weight of machinery, etc.
	Movement can be controlled.
	Angular deflection, if designed.
