Oil and Gas Pipeline Residual Strength Research Based on Reliability Analysis

摘要：

　　Strength of residual wall thickness reliability was studied by Monte-Carlo and finite element method, based on 40in X70 steel and 48in X80 steel which were often used in oil and gas transport pipeline.Pipe with defects in different residual wall thinkness, calculated the critical residual value of wall thickness, and analysed the defect depth and width of influence on pipe reliability.The results provide basis for pipeline safety evaluation and reasonable replacement.
