ABSTRACT:
A pipe restraint having a helical isolator (I.sup.1) coupled to a housing (16) and including a central cylinder (4) coupled to a central rod (2). Connecting rods (34, 36) are located at opposite ends of the restraint to attach the restraint between a pipe and an adjacent structure. Wire energy absorbing rope bights (32) are used to form the isolator I.sup.1. The bights (32) are placed in a state of precompression and have bi-linear spring properties which may be adjusted by adjusting the diameter of the housing (16) and spacer bar ( 30).
