This range is comprised of hinged expansion joints having stainless steel membranes, carbon steel flanges, and a single internal stainless steel sleeve. These expansion joints are designed to permit regular rotation in one plane only by the use of a pair of pins through hinge plates, attached to the flanges. The hinges and pins are designed to restrain the thrust of the expansion joint due to internal pressure. These expansion joints are used in sets of two or three or with gimbal expansion joints.
