[History of the Haichuan Pipeline] my country’s first comprehensive domestic natural gas project - the China-Russia East Route Natural Gas Pipeline

The Heihe-Changling section project faces many difficulties and challenges: First, this project is currently the largest long-distance natural gas pipeline project in my country. The project also uses a combination of 1422mm ultra-large diameter, X80 high steel grade, and 12MPa high pressure. This combination is the first in my country's pipeline engineering construction and has world-class scale and level. Second, construction is difficult. There are dense forests along the pipeline, and the lowest temperature in winter is -40 degrees Celsius℃ ； In summer, large areas of swampy wetlands, poor social support, extremely high construction difficulty, and complex and diverse natural environments pose huge challenges to pipeline construction. Third, this project is my country's first smart pipeline pilot project. It has the most new materials, new technologies, and new processes, and has the highest degree of informatization, automation, and intelligence. It requires a lot of exploration and practice from "0" to "1".

The Heihe-Changling section of the China-Russia east-line natural gas pipeline has been fully connected, marking the full entry into production and laying a solid foundation for the official receipt of Russian gas on December 1. This project is my country's first fully domestically produced natural gas pipeline project, and its project quality has reached the world's first-class level. Among them, the core equipment known as the "heart" of the pipeline - the natural gas long-distance pipeline compressor is provided by Shengu Group.

In fact, negotiations on the construction of the China-Russia east-route natural gas pipeline have been going on for a long time. China and Russia started negotiating on the project in the 1990s, but it was not until May 2014 that the gas supply contract was officially signed. Although the pipeline project consultation took 18 years, since full-scale construction began at the end of 2017, the construction of the northern section was completed and put into operation in just a few years. This ultra-large-diameter pipeline using world-class construction standards once again proves China's speed. The first contract period for the China-Russia east-route natural gas pipeline is 30 years. The initial plan is to transport 5 billion cubic meters of natural gas to my country within one year, eventually reaching an annual input scale of 38 billion cubic meters.

20200724 Construction of the southern section of the China-Russia east-route natural gas pipeline officially started#] Reporter from* * Pipeline Network Group learned that the Yangtze River Shield crossing project of the southern section of the China-Russia East Line Natural Gas Pipeline (Yongqing-Shanghai Section) started on the 28th, marking the official start of the construction of the southern section of the China-Russia East Line Natural Gas Pipeline. The Yangtze River Shield Crossing Project is scheduled to be completed and put into operation in June 2025. By then, Russian gas passing through Northeast China, North China and other places can be transported to the Yangtze River Delta region, and it can supply 18.9 billion cubic meters of natural gas to the Yangtze River Delta region every year.

2018-01-16 · On January 16, the official account of "Liaoshen Evening News", the reporter learned during an interview at Anshan Iron and Steel that since May 2017, Anshan Iron and Steel has accumulated a total of”* * The key project - the China-Russia East Route Natural Gas Pipeline Project provides 18,000 tons of ultra-wide, thick-walled, high-performance X80M pipeline steel, accounting for more than 60% of the project's first batch of supply, providing strong support for the world's largest onshore energy channel to "gas through China and Russia" as soon as possible.

According to reports, the China-Russia east-route natural gas pipeline project is my country's first cross-border long-distance natural gas pipeline project with the largest single-pipeline transmission volume in the world, using 1422 mm ultra-large diameter, X80 high-performance pipes, and 12 MPa high-pressure grade. The total length of the project pipeline is about 3,371 kilometers, starting from Heihe, Heilongjiang in the north, to Shanghai in the south, passing through 9 provinces, autonomous regions and municipalities. After completion, it is expected to provide 38 billion cubic meters of natural gas to my country every year. It is understood that starting in May 2017, the Anshan Iron and Steel Pipeline Steel Production, Sales and Research Team made full use of the equipment and technical advantages of the 5500 mm wide and thick plate production line of the Bayuquan Branch of Anshan Iron and Steel Co., Ltd. to overcome many technical problems such as high rolling load and poor performance uniformity of ultra-wide and thick-walled pipeline steel. In order to ensure that the products meet the harsh conditions of the engineering site, the Angang Pipeline Steel Production, Sales and Research Team improved the low-temperature impact test standards, strengthened steel plate shape control and improved dimensional accuracy, and successfully developed ultra-wide and thick-walled X80M pipeline steel, which successfully passed user inspection and achieved batch supply.
