An approach to the problem of predicting reaction forces that can occur during pipe failure is provided. Use is made of experimental data measuring crack propagation speed to determine the pipe rupture forces. The results of this paper are for pipelines carrying subcooled liquid water, but may be applied to other fluids. The reaction forces during pipe

Failure Analysis on a Ruptured Petrochemical Pipe
Practical Metallography, 2010Abstract The failure took place on a welded elbow pipe which exhibited a catastrophic transverse rupture. The failure was located on the welding HAZ region, parallel to the welding path. Branching cracks were detected at the edge of the rupture area. Deposits of corrosion products were also spotted.

‘Plug and pipe’ strategy for treatment of ruptured intracranial aneurysms
Journal of NeuroInterventional Surgery, 2018BackgroundAneurysmal subarachnoid hemorrhage is a potentially devastating condition, and among the first priorities of treatment is aneurysm occlusion to prevent re-hemorrhage. An emerging strategy to treat patients whose aneurysms are not ideal for surgical or endovascular treatment is subtotal coiling followed by flow diversion in the recovery phase ...

Pneumatic Rupture of a Brittle Pipe: The Depressurization Transient Adjacent to the Ruptured Zone
Journal of Pressure Vessel Technology, 1981A simple theoretical model is developed to predict the pressure transient within a gas-pressurized pipe when an adjacent section shatters into many fragments. Comparison with experiment shows that the model correctly predicts the general form of the transient over a wide range of bursting pressure and rupture zone lengths, though the measured initial ...

Rupture strength of welded T-joints on pipes
Strength of Materials, 1992Results are presented from experimental studies of the rupture strength of models of welded T-joints made of heat-resistant steel. Rupture strength is determined while the joint is subjected to internal pressure. The finite-elements method and a modification of the Neuber method are used as a basis for a new approach to predicting the strength of T ...

Probability of Rupture for WWER-1000 Main Piping
Volume 2: Nuclear Policy; Nuclear Safety, Security, and Cyber Security; Operating Plant Experience; Probabilistic Risk Assessments; SMR and Advanced Reactors, 2020Abstract A probability of rupture for WWER-1000 main piping was calculated based on the Failure Assessment Diagram (FAD), treating material properties of welds (the most likely zone for crack growing and its nucleation) and crack morphology parameters as stochastic values.

Development of a Probabilistic Pipe Rupture Assessment Code
ASME 2010 Pressure Vessels and Piping Conference: Volume 6, Parts A and B, 2010Appendix A, General Design Criteria (GDC) 4, of 10 CFR Part 50 states, in part, that the dynamic effects associated with postulated reactor coolant system pipe ruptures may be excluded from the design basis when analyses reviewed and approved by NRC demonstrate that the probability of fluid system piping rupture is extremely low under conditions ...

Design and Experimental Research on a New Pipe Rupture Valve
Frontiers of Mechanical Engineering in China, 2006A new pipe rupture valve for hydraulic elevator is designed. Mathematical models established for the hydraulic elevator system are used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameters, inlet pressures of pipe rupture valve, and elevator loads on the hydraulic elevator system’s ...

Numerical Modeling of Full-Scale Pipe Rupture Tests
Journal of Pressure Vessel Technology, Transactions of the ASME, 1992The split-ring model is used to simulate full-scale pipe rupture experiments. Using experimentally measured pressures and pipe material characteristics, the model correctly predicts crack extension histories and depressurization rates. The model is also successful in predicting the occurrence of crack arrest and the arrest length.
