With the call of energy saving and emission reduction, natural gas, as a kind of clean energy with abundant green and environmental reserves, has gradually become the main source of domestic fuel for Chinese residents. The urban gas pipeline network system has also become a part of the urban basic service facilities, providing energy for the city. The safe operation of the gas pipeline network is closely related to the daily production and life of the people. Because of the economic and other reasons, there are many old gas pipelines in the central city of Changling County. In addition, there is no effective renewal for a long time. These pipelines are running ill, the overall gas distribution is seriously reduced, and there is a leakage phenomenon. There are great potential safety hazards, which also causes a great waste of energy. Therefore, in this context, the government of Changling County takes active measures to solve the problem of the old gas pipeline network in the central city, and promotes the task of gas pipeline network transformation.
