摘　　要：热收缩带广泛应用于燃气管道3PE防腐层补口,良好的补口是燃气管道防腐层质量的保障。通过建立燃气管道热收缩带补口失效的故障树,运用布尔代数求出补口失效故障树的最小割集,计算出各个基本事件的结构重要度系数,并按照结构重要度系数的大小对各个基本事件进行了排序。文章通过故障树分析,得出了热收缩带补口失效的原因,得到了热收缩带补口失效的主要危险源,并从三个方面提出预防和控制热收缩带补口失效的建议。Heat shrinkable tapes are widely used in the joints of 3PE anticorrosion fuel gas pipeline,and good joint quality ensures anticorrosion quality of pipeline.This paper constructs a fault tree model of joint failure with heat shrinkable tapes,finds the fault tree minimal cut sets using Boolean algebra,calculates the structural importance coefficients of all basic events,then sequences the basic events according to the importance coefficients.Through the fault tree analysis,the causes and the main hazardous sources of the joint failure are found.Finally,suggestions for preventing and controlling the joint failure with heat shrinkable tapes are given in three aspects.
