长输管道安全技术浅析

Security Analysis of Long-distance Pipeline

长输管道系统是一个复杂的系统工程,涉及上游的气田、输气站场、管道、储气库和下游的各个用户,其任何一处出现问题都将影响整个系统的安全运行。天然气具有易燃、易爆和毒性等特点,一旦管道系统发生事故,将很容易引发重大火灾,甚至产生爆炸、中毒、污染环境、人员伤亡等恶性后果,不仅会造成严重的人员伤亡及重大经济损失,同时也会造成非常恶劣的社会影响。因此对长输管道的安全技术进行分析具有重要的意义。

Long-distance pipeline system is a complex systematic project, connecting the upstream gas field, gas stations, pipelines, gas storages to the downstream users. The malfunction of any part could adversely affect the entire system, causing the problems in gas supply. Moreover, since the natural gas is explosive and toxic, once the pipeline system breaks down, it will cause severe consequences, leading to not only heavy casualties and serious economic losses but also negative social and political influences. Hence, the security analysis of the long-distance pipeline is of great value.
