本文以山东管道为例,对引起长输管道失效的内因和外因进行分析。首先根据引起管网失效的四个最直接的原因(第三方破坏,管道腐蚀,管道材料缺陷和管道附属设备失效)展开分析,用故障树对山东管道失效进行定性分析,确定故障树的最小割集,找出事故发生的薄弱环节。其不仅可以作为编制HSE检查表的重要依据,同时故障树分析的结果可为山东管道老管网的维护和济青二线的设计提供理论指导,又可达到预测和预防事故发生的目的。
In this paper, Shandong Pipeline is taken as an example to analyze the internal and external causes of the long-distance pipeline failure. First of all, according to the four most direct causes (third-party damage, pipeline corrosion, pipeline material defects and pipeline attachment failure) that cause the network failure, the paper analyzes the failure of Shandong pipeline by fault tree and determines the minimum cut of the fault tree Set, identify the weaknesses of the accident. It can not only serve as an important basis for compiling HSE checklist, but also provide the theoretical guidance for the maintenance of the old pipeline network in Shandong and the design of Jiqing second-line. The results of fault tree analysis can also achieve the purpose of forecasting and preventing accidents.
