天然气长输管道安装关键过程存在的问题及应对措施

Problems and Countermeasures in the Key Process of Installing Long-distance Natural Gas Pipelines

天然气长输管道安装施工过程涉及诸多重要环节,每个环节的施工质量都会对管道本体产生重要影响,给管道的运行留下安全隐患。文章就天然气长输管道安装施工过程中的焊接、无损检测、防腐补口、压力试验及交工技术资料的编制等关键环节存在的一些问题进行了总结分析,提出了相应的解决应对措施。

The installation and construction process of natural gas long-distance pipelines involves many important links,and the construction quality of each link will have an important impact on the body of the pipeline,leaving safety hazards for the operation of the pipeline.This paper summarises and analyses some of the problems in welding,non-destructive testing,anti-corrosion patching,pressure testing and the preparation of technical data for delivery in the installation and construction of long-distance natural gas pipelines,and proposes corresponding measures to effectively improve the quality of work.
