长输油气管道并行敷设合理距离分析

文章介绍了国内、欧美及前苏联国家规范中管道并行间距的有关规定,在深入分析了影响管道并行间距的安全、施工、维抢修、阴极保护、爆破施工、管道爆炸等因素后,提出了长输油气管道并行敷设的合理间距:在采用机械化施工的一般地段其合理距离为施工间距,在无法采用机械化施工的地段其合理间距为维抢修间距,局部难点段在采取安全措施后可以采用同沟敷设。

The article describes the regulations of distance between parallel pipelines in China, Europe and American, and countries of former Soviet Union. Based on deeply analyzing the elements which influence the security, construction, maintenance and repair, catholic protection, blast working, it suggests the reasonable distance between parallel pipelines for long distance oil and gas transmission pipeline projects. The conclusion is that the reasonable distance in general areas where the construction equipment can work is the construction distance; the reasonable distance in special areas where the construction equipment can not work is the distance for maintenance and repair, and dual laying in one ditch for pipelines can be used in some hard areas by security measures.
