Expansion Joint: Hinged

This expansion joint contains a single bellows and it is designed to permit angular rotation in one plane only by the use of a pair of pins running through plates attached to the Expansion Joint ends. The hinge hardware is designed to restrain the pressure thrust load and other additional specified external loads. The anchors and supports requirements are greatly reduced from the required for the Single Unrestrained Expansion Joints. This Expansion Joint is not able to accept axial movement because the hinge hardware is rigid in the axial direction. Hinged Expansion Joints should be used in sets of two or three or in combination with two Gimbal Expansion joints.
