  • Pipe Joint Restraint
    Publication number: 20200256488
    Abstract: A pipe restraint utilizes a wire grip about an exterior surface of a pipe section to be joined to another structure. The grip applies a gripping force to the pipe section to retain it from outward movement relative to the structure. Some embodiments utilize an internal surface of the structure to assist in applying a force through the grip to the exterior surface. Some embodiments utilize a separate gland to assist in applying force through the grip to the exterior surface. Still other embodiments direct forces through a flange on the structure to pull wires about the exterior surface of the pipe section.
