Webb1 nov. 1974 · A pipe whip restraint utilizing the dissipative capacity of a plastically deforming element has been developed. The transient dynamic behavior of the pipe and the restraint is studied using a discrete mathematical model consisting of nonlinear spring, mass, and damper elements.

WebbIt is concluded that progress in the design of piping systems in compliance with current regulatory requirements for such a postulated event depends primarily on the … WebbPipe Whip Protection Measures Measures for the protection of structures, systems, and components important to safety should be provided after piping break locations are …
WebbPipe whip restraints should, by means of deforming components, be able to absorb the energy of a ruptured pipe accelerated by the fluid reaction force. Since the elastic deformation of the restraint material is not sufficient for this purpose, or would result in excessive anchor loads, pipe whip restraints must generally be designed to work in the …
