ABSTRACT:
A pipe restraint and methods for its use are disclosed. The pipe restraint includes a hollow cylindrical housing of varying diameter. A shaft having first and second wedges is received by the housing. The housing is attached to a fixed structural member, such as a wall and the shaft is attached to the pipe. Depending on the force being applied to the pipe, one of the wedges engages the housing at a point where the diameter changes. The housing's resistance to movement of the wedges varies between two points of differing diameter of the housing. In one embodiment a disc spring assembly is located at one end of the housing. In one method a gapped restraint is attached to a pipe and the size of the gap in the restraint is less than the anticipated movement of the pipe due to a static load.
