[Objective] Girth welds are known to be vulnerable locations along high-pressure transmission pipelines due to their susceptibility to cracking accidents under the combined action of internal and external loads, as well as defects and stress concentr

The equal outer diameter design(the inner-tapered bevel design) of onshore high-grade large-diameter natural gas pipelines has effectively improved the quality problems of welding at place of pipeline with unequal wall thickness.However, the problems

Among the failure modes of high-grade steel pipelines, cracking or leakage failures of girth welds account for nearly 1/3 in total. Thus, different assessment methods are adopted for various types of indicators, and a risk assessment method based on

Nowadays, failure of girth weld is a main risk factor for the operation of high-grade long-distance pipelines.Through the analysis on girth welds of failed pipelines, it is found that the strength of girth welds lower than that of the pipe body is on
