基于雷-菲法的油气管道可靠性分析
Reliability Analysis of Oil and Gas Pipeline Based on R-F Method
摘要
Abstract
Factors that affect pipeline safety and reliability are numerous and randomness,so directly solving the limit state equation is difficult.The solving process of using R-F method is simple and high precision.Based on reliability theory and B31G-1991 standard,comprehensively considering the randomness of the corrosion defect length,radial depth of defect,thecorrosion rate,wall thickness,pipe yield strength and pressure pipelines,using R-F method established a mathematical model for the reliability analysis of corrosion piping.The computer program for this method was developed.The results show that reliability index of the pipe decreased with the increase of defect length,defect depth,and the radial in corrosion rate and that the defect depth is the main factor of pipeline failure.The pipeline reliability index with the pipe yield strength increases in a linear increased,and rapidly reduces with inside pressure increasing.关键词
