A Hinged Metal Expansion Joint contains one bellow and is designed to absorb angular rotation in one plane only by one pair of hinges. The hinges and hinge pins must be designed to restrain the thrust of the expansion joint due to internal pressure and extraneous forces.. Hinged expansion joints should be used in sets of two or three bonded to absorb combinations of movements in the piping system.
