ABSTRACT:
A force absorbing restraining system for a number of pipe sections, each having an integral restraining system which is subsequently connected and works in conjunction with the integral restraining system of adjacent pipe sections. It is known that during an explosive failure either of a pipe section or a joint between pipe sections, a tremendous amount of reaction force is generated by escaping effluent flow. This force, in turn, may energize equipment such as pipes, pumps, and the like to exhibit uncontrolled motion often at a rate of several hundred feet per second. The restraining system of the present invention is designed to absorb a sudden burst of explosive energy and to lessen the reaction forces generated by the explosion so as to ensure that equipment does not move about a service site in an uncontrolled manner which could injure people and damage buildings or other equipment. In short, the force absorbing restraining system in accordance with the present invention reduces the effects of impact loading during explosive failure by dissipating energy in the permanent mechanical deformation of an integral restraining tube assembly attached to each pipe section.
