油气管道线路工程设计中的几个问题

Several problems in the engineering design of oil and gas pipeline

指出油气管道线路工程在管道设计压力、管道试压、钢管选择、山区选线与敷设、大开挖埋管穿越河流、埋地管道涂敷内涂层6个方面需要注意的问题,并给出解决办法。

With the development of pipeline,more stringent requirements for pipeline engineering design are put forward. Six problems needed to pay attention to in oil and gas pipeline design,including design pressure and test pressure of the pipeline,steel pipeline selection,mountain line selection and laying,pipeline crossing-river with large excavation and coating inner layers for buried pipeline,are pointed out. The corresponding solutions are also proposed.
