天燃气管道设计常见问题的探讨

Discussion on Common Problems in Natural Gas Pipeline Design

近几年,城镇燃气管道敷设长度不断增加。天然气是经过生物化学、地质变质作用积存的可燃气体,由油气田开采后经过净化送入城镇燃气用户家中,因其主要成分为密度小于空气的甲烷,易燃易爆性较为突出。一旦管理不到位,就会引发燃气管道安全事故。因此,探究城镇燃气管道天然气安全设计以及运行管理策略具有非常突出的现实意义。

In recent years,the laying length of urban gas pipelines has been increasing.Natural gas is the combustible gas accumulated through biochemical and geological metamorphism.After being extracted from oil and gas fields,it is purified and sent to the homes of urban gas users.Because its main component is methane,which is less dense than air,its flammability and explosiveness are more prominent.Once the management is not in place,it will lead to gas pipeline safety accidents.Therefore,exploring the safety design and operation management strategies of natural gas in urban gas pipelines has very prominent practical significance.
