Webb1 nov. 1985 · Energy balance methods commonly in use for the design of pipe whip restraints are based on the solution for the motion of a rigid-plastic pipe before impact against the restraint, with the assumption that after impact, the whipping portion of the pipe continues to rotate about the plastic hinge location determined for conditions … Webb1 jan. 1984 · It is well recognized in the nuclear industry that the current methodology for pipe whip restraint design is overly conservative and not cost effective. This conservatism neglects to account for strain rate and geometrical nonlinearity effects associated with large deformation during the pipe whip and impact.

WebbA nonlinear dynamic Finite Element Analysis (FEA) is then conducted using ANSYS-LS DYNA program in order to simulate the smashing of a whipping pipe against its own restraint. Break locations will be identified, the thrust force will be computed, plastic hinge formation evaluated, stress-strain curve outlined. WebbWhip Checks can be attached hose to hose or hose to equipment. Whip Checks are highly resistant to rust and corrosion, additionally whip checks do not require any tools to install. We suggest using whip checks for air hose applications. CHC-CHOKER - Safety Cable Choker (Large Sizes 1-1/2" to 12") 6 Items HHT - Heavy Duty Hose Halters - Round One

WebbPipe Rupture Requirements" would allow elimination of a significant number of the arbitrary intermediate breaks and, thus, a large number of high energy pipe whip restraints are no longer required. The licensee argued that the safety factor of two for concrete expansion anchors for high energy pipe whip restraints should be acceptable because no 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 …
