Hinged Expansion Joint

When a Our Apex Hinged Expansion Joint is used, movement is limited to angulation in one plane. Hinged Assemblies are normally used in sets of two or three to absorb large amounts of expansion in high pressure piping systems. Only low spring forces are transmitted to the equipment. The hinge hardware is designed to carry the pressure thrust of the system. Slotted Hinged, Expansion Joints are a varient of the standard Hinged Expansion Joints that allow axial and angular movement. Be careful! Once Slotted Hinge is introduced torison in the piping system is still resisted but the hinge no longer carries pressure thrust.
