摘要
长输天然气管道工程比较复杂,一旦出现事故,将不能向下游正常供气。因此,天然气管道的安全问题显得尤为重要。根据国内外天然气管道事故的统计数据,对事故原因进行了分析。分析结果表明:外部干扰、腐蚀、施工和材料缺陷是国内外天然气管道事故的三大主要原因。对这些原因的特点作了具体的描述,为国内天然气管道安全管理工作提供了借鉴材料。
Gas transmission pipeline is a complex system. Once an accident happens, it can not provide gas for down line.Therefore, the safety issue of gas transmission pipeline becomes quite important. Statistic data on overseas and internal gas transmission pipeline show that external interference, corrosion and construction defect/material failure are the main causes of gas pipeline accidents . Meanwhile, the characteristic of every cause is analized, so that it can provide some experience for the safety of internal gas transmission pipeline.
