概述随着全球能源产业的迅猛发展,油气储运工作显得尤为重要,长距离输油输气管道的维护工作也成为重点工程。油气管道泄漏不仅会造成油气损失,而且污染环境,甚至有可能引发火灾、爆炸等事故,因此,确保管道的安全使用非常重要。油气管道发生泄漏的原因是多方面的,主要可分为3大类:腐蚀穿孔、 Overview With the rapid development of the global energy industry, oil and gas storage and transportation work has become particularly important. Maintenance of long-distance oil and gas transmission pipelines has also become a key project. Leakage of oil and gas pipelines not only causes the loss of oil and gas, but also pollutes the environment and may even cause accidents such as fire and explosion. Therefore, it is very important to ensure the safe use of pipelines. Oil and gas pipelines leaks are many reasons, can be divided into three categories: corrosion perforation,
