The news comes from online sharing —————————— Report by the China Youth Daily app (Reporters: Sun Haihua from China Youth Daily and China Youth Network; Correspondents: Wang Minna, Li Shaobo) Hard work brings early spring, and the workshops are busy ensuring supply. On March 19, in the workshops of China National Petroleum Corporation Baoji Petroleum Pipe Co., Ltd., machines were humming and sparks were flying as the steel pipes needed for the China-Russia East Pipeline (Southern Section) project were being processed in an orderly manner on the production lines. Feeding, pre-welding, final welding, inspection… All teams work closely together to improve quality and efficiency while increasing production volume, working overtime to meet deadlines. To date, 2,779 tons of steel pipes for the project have been produced in total within 3 days before commencement, with 1,147.4 tons of these pipes shipped. The China-Russia Eastern Gas Pipeline Project is the first of its kind in China to feature an ultra-large diameter of 1,422 millimeters, a high steel grade of X80, and a high pressure level of 12 megapascals; it represents a world-class gas pipeline project. It is capable of transporting 38 billion cubic meters of natural gas from Russia each year, which is equivalent to one-seventh of China’s annual gas consumption. As a **key player in energy infrastructure development, Baoji Steel Pipe Company has pursued technological innovation and successfully developed straight-seam submerged arc welded pipe products with a diameter of 1422 millimeters and wall thicknesses of 21.4, 25.7, 30.8, and 38 millimeters. Since October 2017, over 600,000 tons of high-quality pipeline products have been supplied for the construction of the northern and central sections of the China-Russia East Route. In 2021, Baoji Steel Pipe won the bid for the 180,000-ton order related to the construction project at the southern end of the China-Russia East Route pipeline network, for the first time.

The China-Russia East Route Gas Pipeline: The China-Russia East Route pipeline project is a joint venture between CNPC and Gazprom, and it includes the Siberian Power Pipeline in Russia and the China-Russia East Route Gas Pipeline in China. The China-Russia East Route natural gas pipeline starts in Eastern Siberia, Russia, and enters Heihe City in Heilongjiang Province, China, via Blagoveshchensk. The total length of pipelines within Russia is about 3,000 kilometers; in China, 3,371 kilometers of new pipelines have been built, while 1,740 kilometers make use of existing pipelines. In May 2014, the project was signed for a period of 30 years. At 17:00 on the afternoon of December 2, 2019, following orders from the heads of state of China and Russia, the China-Russia East Gas Pipeline was officially put into operation. At 9:36 on December 3, 2020, the middle section of the China-Russia East Route project, which had been under construction for over 500 days, came to a successful conclusion and was put into official operation.
