Rubber Expansion Joint

20HG, Hinged Expansion Joint

Hinged type rubber expansion joints are designed to permit angular rotation in one plane. The arrangement consists of a pair of hinge plates connected with pins and attached to the expansion joints’ external or internal hardware. The hinge assembly must be designed for the internal pressure thrust forces of the system. Hinged type rubber expansion joints can be used in sets of two or three to absorb large lateral movement in one plane.
They are commonly used when the support structure or adjacent equipment have load limitations.
