Hinged Universal Expansion Joints
Hinged Universal Expansion Joints have two bellows separated by a pipe spool to accept large lateral movements. The ability to resist pressure thrust is provided by a hinge assembly at each bellows, which also permits angular movement in a single plane. Unlike the tied universal, the thermal expansion of the entire expansion joint is applied to the piping as if the joint was just another length of pipe.
