In order to fulfill the construction task of the second-line oil pipeline project of China and Russia on time with high quality and quantity

the project Department of the second-line oil pipeline of China and Russia has organized and held many process evaluation seminars and put forward a scheme to guarantee the construction task of the second-line oil pipeline of China and Russia. Efficient and fast CRC automatic welding process is adopted as a feasible solution for the main line welding process in a feasible location. According to CRC automatic welding process and construction site characteristics

the project department carried out CRC pipeline automatic welding process assessment before the start of construction

optimized the configuration of CRC automatic welding machine personnel and equipment

CRC automatic welding process after the start of the project site inspection and field application showed that CRC automatic welding process square. The case is completely feasible and applicable in the second-line project of Sino-Russian crude oil pipeline. Its successful application improves the construction efficiency and progress of the project

and verifies the characteristics of rapid and efficient construction technology

which accumulates experience for future pipeline construction.
