Xionggu Electrical Continues Serving Sino-Russia Pipeline

The Sino-Russia gas pipeline project has a mainline length of more than 3000 km including three phases. Phase 1 and 2 were put into operation in 2019 and 2020. Phase 3 starts from Yongqing in Hebei Province, passing through three provinces from the north to the south all the way to Shanghai City. The length of the mainline to be constructed is 1243 km and it is expected to be put into operation in 2025, resulting in natural gas being transmitted from Russia to Shanghai.

In the meantime, the pipeline will connect the completed Northeast China, North China and East China pipe networks. The daily gas transmission capacity will exceed 50 million cubic meters. Sixty spreads of Xionggu internal welding machines plus dual torch external welding machines have been in service in this project up to April 2021. Phase 3 of the Sino-Russia pipeline passes through four provincial administrative regions with developed economies, dense populations and a dense water network. There are 94 large and medium-sized rivers across the whole line, 46 environmentally sensitive points such as an aquatic germ plasm resources reserve and wetland park, 2 cultural relics and 83 ecological protection red line areas. The construction technology is complex and the requirements of safety and environmental protection are very high.
