Hinged expansion joints

Hinged single expansion joint consists of metal bellows, flanges or pipe ends and restraint system with axis of rotation. The hinged expansion joint can only accept angular movement. The pressure load produced by internal pressure is constrained by hinged parts and it is not necessary to install strong fix points and robust guiding in piping system. The pair of hinged expansion joints is convenient for pipeline with long movements.
