随着管道输送工艺的不断发展,管道输送以其输送成本低、管理方便等优势,在各个领域的应用越来越广。一、我国油气管道的安全管理现状管道泄漏是长输管道平稳运营的重要安全隐患。根据泄漏量的不同,管道泄漏一般分为小漏、中漏、大漏。小漏亦称砂眼,泄漏量低于正常输量的3,主要是由于管道防腐层被破坏,管壁在土壤电化学腐蚀作用下出现锈点,腐蚀逐渐
With the continuous development of pipeline transportation technology, pipeline transportation has been widely used in various fields due to its advantages of low transportation cost and convenient management. First, the status quo of China’s oil and gas pipe safety management Pipeline leakage is an important long-distance pipeline operators an important security risk. According to the different amount of leakage, pipeline leaks are generally divided into small leaks, leakage, leaks. Small leaks, also known as trachoma, the amount of leakage is lower than the normal output of 3, mainly due to the destruction of the pipeline coating, the wall corrosion of soil under the action of electrochemical corrosion, corrosion gradually
