天然气场站动火连头技术探究

Study on the Butt Welding Technology of the Pipeline with Gas in Natural Gas Sites

天然气管道工程建设以及油气田改扩建的迅速发展,站场扩建、改建以及管道改造愈来愈多,使得管道动火连头成为必不可少的施工步骤。基于陕京三线榆林首站一期及二期两次扩建工程动火连头作业实例,选取特例,对场站动火连头施工技术措施进行进一步的分析,并提出了相关的处理措施.

With the quick development of natural gas pipeline construction and oil-gas field renovation and expansion construction, the application of the welding technology in natural gas sites will be more and more. Taking the application of the welding technology in Yulin Station in the once and seeondary expansion construction of Station in the third Shaanxi-Beijing pipeline as an example, the wehting technology in natural gas sites is analyzed further, some measures are proposed.
