一般来说,长输天然气管道的工程建设都比较复杂,需要一定的基础和经验,如果真要出现了事故,那就会造成极大的影响,最直接的影响就是下游无法正常供气。所以,可以看出天然气管道对人们供暖问题是多么的重要,其安全性能更是我们应该重视的方面。根据多年来国内外各方面专家统计的事故情况来看,事故原因经常是多种可能性。通过总结,我们可以得到以下几点重要影响因素:外部干扰、腐蚀、施工和材料缺陷这三个原因,本文中,作者对这些原因都做出了较为详细的介绍,为国内天然气管道安全事故的预防工作提出一点意见和建议。
In general, the construction of long-distance natural gas pipelines are complex and require some foundation and experience. If an accident really occurs, it will have a huge impact. The most direct impact is that the downstream can not supply gas normally. Therefore, it can be seen how natural gas pipeline heating issues for people is so important, and its safety performance is more important aspects that we should pay attention to. According to statistics of many domestic and foreign experts over the years the accident situation, the cause of the accident is often a variety of possibilities. By summarizing, we can get the following important factors: external interference, corrosion, construction and material defects of these three reasons, the author of these reasons have made a more detailed introduction for the domestic natural gas pipeline safety accident Preventive work put forward a few comments and suggestions.
