对天然气管道焊接检测标准的讨论——以西气东输中卫黄河跨越工程为例

以国家重点工程西气东输中卫黄河跨越工程为例，对比分析了钢结构对接焊缝的质量检测标准中行业标准与国家标准的差别，认为行业标准严于国家标准且更具有针对性。在中卫黄河跨越工程钢结构焊缝质量检测标准中，采用的焊接检测方法达到了国内先进水平，对今后类似工程的设计施工标准选用具有重要参考意义。

A discussion on the gas pipeline welding inspection standard: A case study of the West-to-East Gas Pipeline in Zhongwei crossing over the Yellow River

aking the Zhongwei project of the West to East gas pipeline crossing over the Yellow River as a case of study, this paper discussed in detail on the ultrasonic test standard of steel structure's welding line, and then pointed out that there is difference on the standard between this sector and the national, demonstrating that the former is stricter than the latter. The adopted ultrasonic test method in the above mentioned project has reached up to a national advanced level, which will provide good references for better standard selections on similar engineering design and operation works.
