On February 26, the cumulative gas transmission volume of the Shan-Jing Pipeline System, operated by the National Pipeline Network Group, exceeded 800 billion cubic meters, injecting strong momentum into safeguarding public welfare and promoting regional coordinated development. The system currently transmits an average of approximately 200 million cubic meters of gas per day, with a peak daily transmission volume surpassing 309 million cubic meters. This robust operation reliably meets over 95% of Beijing's natural gas demand.
As a vital component of China's integrated national natural gas network, the Shan-Jing Pipeline System primarily consists of Lines 1, 2, 3, and 4, spanning a total length of 5,599 kilometers. Its supply network covers more than 70 cities across multiple provinces and regions, including Beijing, Tianjin, Hebei, Shaanxi, Shanxi, and Inner Mongolia, serving thousands of large and medium-sized enterprises.
In recent years, the system has continuously enhanced its layout, including the "Five Major Channels into Beijing" and the pipeline network surrounding the capital. It annually transports 97.2 billion cubic meters of commercial natural gas, cumulatively reducing social energy costs by nearly 3 billion yuan and providing substantial support for the coordinated development of the Beijing-Tianjin-Hebei region. Since the commissioning of Shan-Jing Line 1 in 1997, the system has maintained safe and stable operation for 28 consecutive years without interruption.
A representative from Beijing Pipeline Company stated that achieving the 800 billion cubic meter milestone reflects a commitment to public supply security, a contribution to green development, and a testament to technological innovation.
Calculations indicate that the cumulative transmission of 800 billion cubic meters of natural gas is equivalent to replacing approximately 1.07 billion tons of standard coal, reducing carbon dioxide emissions by 1.17 billion tons. The environmental benefits are comparable to planting broad-leaved forests covering 3.633 billion hectares. In 2025, Beijing recorded 311 days of good air quality, an increase of 21 days year-on-year, with the excellent air quality rate reaching 85.2%, exceeding 80% for the first time. This improvement has translated into a tangible sense of "blue sky happiness" for residents.
The continuous enhancement of supply assurance capabilities, particularly at compressor stations, is supported by both the coordinated allocation of interconnected pipeline resources and the application of intelligent operation and maintenance technologies. In Hebei, the Anping Operation Area, a critical hub of the system, utilizes a "seven-inlet, ten-outlet" process layout to achieve interconnection with major national pipelines, including the "North Gas to South" energy corridor. This setup enables an additional daily transmission capacity of nearly 100 million cubic meters of gas to downstream regions.
In Beijing, the Miyun Operation Area has innovatively implemented a model integrating intelligent inspection robots with manual patrols. This approach, combined with an AI video analysis system and a smart management platform, has significantly reduced repetitive tasks by 70%. It enables real-time monitoring of equipment status and intelligent early warnings for safety risks, ensuring stable and secure natural gas transmission.
