CAESAR II Version

Specifies a single hinged expansion joint. This type of joint can only angulate about one axis. Pressure thrust is retained internally by the hinge mechanism. Hinge joints are often used in pairs to absorb considerable displacement in a single plane while transmitting very little load to any attached equipment. The piping system must be designed to assure that displacement into the hinges is planar for all types of thermal and occasional loadings to be experienced by the system. Where pressure loads to be absorbed by the hinge mechanism are high, considerable friction forces can be generated that somewhat limits further flexing of the joint. This transmits larger loads than expected back into the piping system.
