Hinge Expansion Joints

This expansion joint contains a single bellows element and is designed to permit angular rotation in one plane only, by utilizing a pair of pins through hinge plates that are attached to the expansion joint ends. The hinge hardware is designed to restrain the pressure thrust load, as well as, any additional customer specified external loads. The hinge hardware is rigid in the axial direction, therefore, the expansion joint is not able to accept axial movement. In a piping system application, the Hinged Expansion Joint is typically used in pairs or threes, or in combination with the Gimbal Expansion Joint. With the hardware restraining the pressure thrust loads, the anchor and support requirements are greatly reduced from the requirements for the Single Unrestrained Expansion Joint.
