... Abstract ASME Section III Div. 5 provides design rules for high temperature applications involving deformations in the creep range. The latest Code edition is mainly focused on component design and guidelines for piping analysis and design is very limited. For piping analysis, the Code refers...

... Abstract Based on a recently developed multi-scale fatigue-fracture-NDE reliability model for uncracked and cracked pipes (see Fong-Marcal-Rainsberger-Heckert-Filliben-Doctor-Finney, PVP2021-62169), we apply the same modeling technique to a comparative study of three approaches to fatigue-life...

... 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...

More precisely, the salient features investigated by shaking table testing are: i) the interaction between a primary moment resisting frame steel structure...

... technology by means of shaking table tests. The test structure is a three-story moment resisting steel frame with vertical and horizontal vessels and cabinets, arranged on the three levels and connected by pipes. The dynamic behaviour of the test structure and of its relative several installations...

... evaluation, the probabilistic fracture mechanics can be applied as a useful evaluation technique for aged piping systems with crack or wall thinning due to the age-related degradation mechanisms. In this study, to advance seismic probabilistic risk assessment methodology of nuclear power plants that have...

... components under BDBE. This paper discusses example applications of our proposed method to vessels and piping. As an example for vessels, the fracture controlled method of a fast reactor vessel was proposed to maintain coolant under high pressure and high temperature conditions. One of the important...

... Abstract Piping systems constitute the most critical portion of process plants. Proper blast and fire design of critical piping systems improve safety and resiliency. Design of piping and pipe supports are typically governed by operating and abnormal load conditions depending on the design...

... Abstract Transient fluid loads in process piping have gained renewed focus recently with the design and construction of many LNG plants. The case of the shockwave (waterhammer) in piping following the rupture of a tube in a STHE has been well studied. Less attention has been paid to the high...

... Abstract Large diameter non-metallic pipes, designed and engineered as conventional aboveground piping to various international standards, have extensive applications. The support points for such piping are designed with cautions such as smaller support spans and avoiding point loads...

The failure mode of piping systems exposed to excessive seismic loading was found to be ratchet deformation followed by fatigue failure through many experimental tests in the past, whereas the failure of Test #37 of Pipe-fitting dynamic reliability program (PFDRP) conducted...

... Abstract An LNG plant is essentially a variety of static and rotating mechanical equipment interconnected by piping. LNG plants contain a significant amount of piping that is characterised by one or more of the following: large diameter, high design pressure, cryogenic temperatures, stainless...

... Abstract Engineered enclosures for the repair of piping, often referred to as clamps, are used to restore the integrity of in-service piping components as an interim measure until the damaged components can be repaired. They are typically used in the petroleum refining and chemical process...

... Abstract The piping, welding and its fittings contributes to around 25–35% of the total material [1] of any process plant. The quantity of the piping and fittings required in critical pipes (lines) is largely influenced by the flexibility requirements to comply with applicable codes. Since...
