In addition, the China-Russia East Route natural gas pipeline project has also set a number of new records in the history of pipeline construction in China: for the first time, the combination of 1422 mm caliber, X80 high steel grade and 12 mpa high pressure has been built into the largest single natural gas long-distance pipeline project in the world. This is also the first pipeline in the history of China's pipeline to fully realize the localization of key equipment and core control system.
