China’s western region accounts for 12% of the country’s oil reserves and natural gas reserves of 26 trillion m3. The total length of the east-west gas pipeline from Tarim in Xinjiang to Shanghai is 4200km. From the Lunnan oilfield in Tarim, Xinjiang, the route passes eastward through Korla, Turpan, Shanshan, Hami, Liuyuan, Zhangye, Wuwei, Lanzhou, Dingxi, Liquan, Luoyang , Xinyang, Hefei, Nanjing and Changzhou, eventually reaching Shanghai. There are two parallel pipes, each with a diameter of 1.5m, each with a natural gas transmission capacity of 12 billion m ~ 3. The estimated amount of investment in trunk pipe exceeds 55 billion yuan, will use 2.07 million tons of steel, consumes 5100 tons of welding rod, and 30 million meters of earthwork for excavation, at the same time
