...Feng Qingshan; Chang Qun; Jia Haidong; Wu Yi; Dai Lianshuang; Cao Yuguang The failure accidents in girth weld of pipelines occur frequently due to the combination of internal defects and external loads. However, the research on the fracture behavior of girth weld defects is relatively poor...

...Youn-Young Jang; Nam-Su Huh; Ik-Joong Kim; Young-Pyo Kim Long-distance pipelines for the transport of oil and natural gas to onshore facilities are mainly fabricated by girth welding, which has been considered as a weak location for cracking. Pipeline rupture due to crack initiation and propagation...

...; published online February 23, 2015. Assoc. Editor: Hardayal S. Mehta. 22 08 2013 07 01 2015 23 02 2015 A key influence factor in the strain-based assessment of pipeline girth weld flaws is weld strength mismatch. Recent research has led to a framework for tensile strain capacity...

... in components subjected to high plastic strains. In this paper, a combined numerical and experimental approach is used to apply the SB-FAD to predict failure from a series of API 5L grades X80 and X100 curved wide plate (CWP) specimens with shallow notches machined into the pipe girth weld. For the CWP...

... that the design of highly overmatching girth welds in high strength pipelines imposes challenges with respect to toughness and tearing resistance [ 8 ], but this issue is not addressed at this point. First, the finite element model and its analysis procedure are briefly introduced. Second, to gain confidence...

... for corrective actions are provided as a cost-effective life management process to maintain the piping system integrity. This paper provides examples demonstrating that the girth welds ranked below the top five to six welds are subject to significantly less applied stress and have substantially more creep...
