中低压燃气管道占压的综合管理

Comprehensive Management of Occupation in Medium and Low Pressure Gas Pipelines

燃气管道占压通常会造成管道受力不均匀和燃气管道受损的情况,比如燃气管道接口松动、变形、断裂等,极易引起燃气泄漏或遇明火爆炸等事故。分析了管道占压的类型、形成原因和占压的危害,并基于GIS地形进行占压辨别、建立占压分析模块和创建隐患台账。同时,探讨了占压燃气管道的综合管理措施及取得的进展,为地下燃气管道巡检及安全评价提供借鉴。

Occupation in gas pipelines usually cause unbalanced force and damage to gas pipelines,such as gas pipeline interface loosening,deformation,fracture,etc.,which can easily cause gas leakage,fiery explosion and other accidents.It analyzes the types,causes and hazards of occupation in pipelines,identifies the occupation,establishes the occupation analysis modules and creates hidden danger accounts based on GIS terrain.At the same time,the comprehensive management measures and progress of occupation in gas pipelines are discussed,which can provide reference for inspection and safety evaluation of underground gas pipelines.
