Oil And Gas Pipeline Rupture Safety Analysis

The history of pipeline fracture is as long as the history of pipeline. The people put forward all kinds of criterion such as the Energy Release Ratio criterion and Stress Intensity Factor criterion for brittle fracture and COD criterion and J Integrity criterion for ductile fracture by studying the fracture of pipeline.Because that brittle fracture and ductile fracture can't be taken apart thoroughly, British Centric Electricity Department and British Standard Association put forward Bi-judge criterion, and it suit not only for brittle fracture but also for ductile fracture. On the basement of Bi-judge criterion, this artic improve it and pose Bi-coefficient method.In Fracture analysis, considering the random of the parameters which are taken as ones with statistics regularity, this is Statistics Fracture analysis .In Fracture analysis, not only the parameters have random but also the other factors have fuzziness. When the random of the parameters and fuzziness of the other factors are both being considered, Fuzzy Probability Fracture analysis is born, and it make the analysis of the fracture accidents in pipeline accord to the fact.
