Abstract

Abstract:

Taking pipeline files and test reports as original materials, and with spot investigation and observation, the pipeline rupture failure was analyzed by adopting “ failure analysis system for in -service pressure pipeline” .The safety situation of pipeline defects was combined with its failure risk.Based on current test data of defects, a rational probability model was chosen to calculate failure risk probability of the pipeline .It' s very helpful to know the safety situation of pipeline , make a proper plan for examining and repairing , enhance pipeline maintenance and ensure the equipment working safely and stably .

Key words: Pipeline , 　Rupture failure risk , 　Defect , 　Probability model

摘要： 　以相关管道档案、检验报告作为原始资料, 配合现场调查及观测, 采用“ 在役压力管道失效风险分析系统(SAPP)” , 对管线断裂失效风险进行分析。将管线中各缺陷安全状况与失效风险有机地结合起来, 在当前检测缺陷数据基础上, 通过适当选取概率模型, 计算管线的失效风险概率。对于准确了解管线的安全状态, 制定具有针对性的检修计划, 加强管线维护, 保障装置的安全稳定运行有重要的现实意义。
