The Technology Status of Fracture Propagation and Crack Arrest of Pipelines

In recent years, the pipelines of oil and gas developed rapidly, but a variety of risks were accompanied. Fracture and crack propagation in pipelines are complex and changeable, which can cause particularly serious consequences. In this paper, underlying causes and outside factors to cause the oil and gas pipeline ruptures were described, the research status and progress in terms of pipeline ruptures were also introduced, and the research achievements in the field of crack propagation and fracture control were summarized.
