... piping circumferential flaw bending plastic collapse flow stress Abstract Allowable stresses for pipes are determined by combining failure stresses and safety factors. When predicting the plastic collapse failure stresses for high toughness ductile pipes, flow stresses of the pipe...

... Abstract Fire suppression piping systems play a crucial role in minimizing the impact of unwanted fires. These systems primarily consist of welded or threaded connections at the pipe/fittings interface. Previous research conducted on threaded connections used the rotation at the pipe-fitting...

... evaluated three steel pipes from industrial contacts to assess the susceptibility of seam welds to hydrogen embrittlement; these three pipes are made from API 5L X65M steel. The three steels were characterized in terms of microstructure, Charpy experiments (performed in air), and fracture toughness via...

... Abstract An inelastic response-spectrum analysis method for multi-degree-of-freedom systems was proposed. The method has lower analysis loads and predictable by the inelastic response-spectrum and is not an equivalent-linearization method. We propose a seismic evaluation method of piping...

... clarified. In a previous study, authors found that the CAV of the piping vibration response can relate to the vibration stress, using the velocity rule from the ASME standard for the Operation and Maintenance (OM) of Nuclear Power Plants. Using the velocity rule, a new evaluation method of cumulative...

... Abstract This paper provides a logical, step-by-step approach to address flow-induced vibration in piping systems and pipelines. Starting with immediate actions when significant vibration is observed, followed by root-cause determination with a description of the various sources of vibratory...

... Abstract Despite the fact that shell elements more accurately model a piping system, beam elements are mainly used to model piping systems. A beam model makes use of SIFs and flexibility factors to account for local geometries in a piping system. Recent advances in software and computer...

... Abstract One of the typical characteristics of high temperature piping systems is that they are more flexible. This is due primarily to expansion stress limits which cause the piping designer to add additional elbows and to minimize axial or lateral stops. The resulting high flexibility and low...
