China–Russia East-Route Natural Gas Pipeline in Operation

The China–Russia East-Route Natural Gas Pipeline was officially put into operation on December 2, 2019. The Pipeline includes the section Russia, often referred to as Power of Siberia gas pipeline, the cross-border section and the section in China. The gas is mainly supplied from the Kovyktinskoye Gas field in Irkutsk Oblast and the Chayandinskoye Gas field in Sakha Republic (Yakutia) in East Siberia, Russia.

The Chinese section of China–Russia East-Route Natural Gas Pipeline with the largest diameter and the highest pressure currently in the country, starts from Heihe city, Heilongjiang Province in the north winding all its way to Shanghai municipality in the south. As planned, it will be constructed and put into operation in three subsections. The north subsection (Heihe City - Changling County) was put into operation this time, and the middle subsection (Changling County - Yongqing County) and the south subsection (Yongqing County - Shanghai City) are scheduled to be launched in 2020 and 2023 respectively.

In May 2014, Gazprom and CNPC signed the Sales and Purchase Agreement for gas to be supplied via the China-Russia East-Route Natural Gas Pipeline. According to the contract, Russia will export gas to China for 30 years via the route since it’s put into operation, and the volume will gradually increase to 38 bcm per annum.

The China–Russia East-Route Natural Gas Pipeline is a landmark project of China-Russia energy cooperation and a paradigm of deep convergence of both countries' interests and win-win cooperation. The operation of the pipeline will further optimize China’s regional gas consumption structure and enable a multisource supply of gas, which is of great significance for China to ensure gas supply in winter and win the Blue Sky Protection Campaign. The construction and operation of the pipeline have also driven the development of infrastructure and supporting industries, created job opportunities, and promoted the economic growth in places along the route.

Technological Innovation & Intelligent Pipeline Construction

To build China's first long-distance gas pipeline of 1,422mm in diameter, the company initiated research on applicable technologies of X80 steel pipes. It took three years to overcome difficulties in pipe manufacturing, fracture control, welding and construction equipment development, and formulated 13 technical standards.


The China–Russia East-Route Natural Gas Pipeline is the company’s first pilot program on intelligent pipeline systems. The project integrates real-time data acquisition and transmission system, intelligent site monitoring system, lifecycle project management system, crew and project management platforms to enable standardized design, intelligent detection, IT-aided management and digital hand-over along the entire pipeline, which has promoted a shift from digital to intelligent pipeline construction for the company.

A Green Project

The Pipeline is also a green project in China. Construction and operation of the Chinese section faced remarkable challenges from the complex geological and topographical conditions, including permafrost, rivers, forests, and natural reserves. During initial pipeline design, the company took into full consideration the potential environmental impacts, and took tailor-made measures for different regions with regards to water protection, forest-fire prevention or layered backfill, in order to minimize the environmental footprints. In particular, culvert and shield crossing techniques and measures were applied in environmentally-sensitive areas such as rivers, lakes, forests, roads and bridges.

When it reaches its full capacity, i.e. 38 billion cubic meters per year, the China–Russia East-Route Natural Gas Pipeline will reduce CO2 and SO2 emissions by 162 and 1.82 million tons respectively each year and significantly contribute to the optimization of China’s energy consumption mix and improvement of air quality in regions along the route.
