Another section of the China-Russia eastern natural gas pipeline put into operation

The autumn breeze sent a good news, and the Sino-Russian east line was fruitful. Recently, in the general control room of the Beijing Dispatching Command Center, with the "ignition" command, the handle of the intake valve slowly turned, and a red fire dragon several meters high jumped up over the "torch". The Tai'an section was officially put into operation.

" China-Russia East Route Natural Gas Pipeline , as the first major third-generation natural gas pipeline project under construction in the country, is a major project to build the country's four major energy transportation channels." Province According to the person in charge of the Petroleum and Natural Gas Division of the Energy Bureau, the Sino-Russian East Line Natural Gas Pipeline starts from Heihe, Heilongjiang in the north, and reaches Baihe, Shanghai in the south, passing through 9 provinces, autonomous regions and municipalities including Heilongjiang, Jilin, Inner Mongolia, Liaoning, Hebei, Tianjin, Shandong, Jiangsu and Shanghai. 5111 kilometers long. Among them, 3,371 kilometers of newly-built pipelines have been approved for construction in three sections: north, middle and south. The northern section (Heilongjiang Heihe-Jilin Changling) and the middle section (Jilin Changling-Hebei Yongqing) have been put into operation. The section from Anping to Tai'an is an important part of the southern section of the China-Russia East Route Natural Gas Pipeline (Yongqing-Shanghai, Hebei). 1219 mm, the design pressure is 10 MPa, the designed annual gas transmission volume is 18.9 billion cubic meters, 23 large and medium-sized rivers, 41 highways and railways above grade, and 4 receiving stations are set up.

The China-Russia East Route Natural Gas Pipeline is the world's first cross-border long-distance natural gas pipeline project that simultaneously adopts large diameter, large wall thickness, high steel grade, high pressure, and the largest single-pipe transmission capacity. The pipeline is fully connected, with a maximum annual gas transmission capacity of 38 billion cubic meters, which can benefit 400 million people along the line. It has become the third cross-border long-distance gas pipeline to supply gas to China after the Central Asia Pipeline and the China-Myanmar Pipeline. , interconnecting the Northeast Pipeline Network, the Shaanxi-Beijing Pipeline Network, the Shandong Pipeline Network, the West-East Gas Pipeline, etc., initially forming a "one network in the country" pattern.

"As my country's first self-constructed and managed smart pipeline, intelligent elements of the Sino-Russian East Route Natural Gas Pipeline are everywhere. From pipe making to laying to operation, from material selection to welding to production, there are multiple factors behind every process. Intelligent technology support. The completed and put into production pipeline is no longer a cold steel pipe, but has the most intelligent 'brain'." The person in charge of the project of National Pipe Network Group introduced, anchoring "full digital handover, full intelligent operation, Full life cycle management " goal, integrate "mobile terminal + cloud computing + big data" and " Internet + unit" and other technical means, make every effort to build a full life cycle intelligent platform, and promote the transformation of pipeline data from scattered distribution to unified sharing , From passive risk management and control to active supervision, from isolation and dispersion to integration and interconnection, and fully realize the intrinsic safety of pipelines. In the progress of project construction, make full use of big data, Internet of Things, mobile application technology, deploy wireless local area network on site, combine QR code, electronic label , cameras, smart gates and mobile phones and other terminal equipment, real-time whole process monitoring, intelligent Perception and data collection to realize intelligent management and control of engineering construction.

According to reports, during the construction of the section from Anping to Tai'an, problems such as complex mountain construction and frequent flooding disasters were successively overcome. In view of the different characteristics of terrain slope and stonework grade, the "two-stage method" was innovatively adopted for design and construction, and the stonework section in the mountainous area was obtained. has made a breakthrough in welding technology; the application of DR digital non-destructive testing, station automatic welding, prefabricated building and other technologies has greatly reduced the construction period and significantly improved the quality and efficiency of the project. In the next step, the national pipeline network will take the opportunity of the completion and operation of the Anping-Taian section of the China-Russia eastern natural gas pipeline to accelerate the construction of the eastern energy channel, and strive to complete the production target of the Tai'an to Taixing section and the Taixing to Luzhi section within this year Task.
