Natural gas from the Bay of Bengal and Central Asia natural gas meet at Tongliang, marking the basic formation of the unified natural gas dispatch pattern in our country with a substantial increase in its guarantee capability. Zhonggui Line, as a national key project for building a national oil and gas trunk pipe network, connects the West-East Gas Pipeline and Shaanxi-Beijing System in the north and Sichuan-Chongqing Pipeline in the south and the Sino-Burmese natural gas pipeline in the south to jointly form large-scale circular pipe networks of different levels , To enhance the flexibility of our pipe network deployment and gas supply security is of great significance. At present, the completion of natural gas pipelines such as the east-west gas transmission project, the east-west gas transmission project and the Shaanxi-Beijing-Sino-Myanmar Burundi and Zhonggui gas pipeline have enabled China to basically achieve natural gas pipe network and diversified gas source
