The continuous improvement of the current economic level has led to a continuous increase in energy demand, rapid development of heating industry, and an increase in heating scale. Directly buried heating pipelines have become the main components in the current energy transportation process due to their advantages of low cost, short construction time, and small footprint, and are widely used in urban heating pipeline networks, petrochemical, urban gas and other projects. With the development of directly buried heating pipeline systems, the technology and scale of directly buried pipeline networks have also increased. Due to reasons such as stress concentration, corrosion, and large deformation, pipelines are prone to leakage and rupture. The increasing demand for energy transportation has led to higher requirements for the diameter and pressure of directly buried heating pipelines, and various safety issues are becoming increasingly prominent. Therefore, the safety of pipelines, as an important link in the transmission process, has received great attention; At the same time, in response to the proposal of energy-saving and environmental protection policies, smart energy systems and the fourth generation of regional heating and cooling technologies are new research hotspots. In response to the energy-saving and efficient needs of various countries, it is particularly crucial to further improve the system efficiency of regional heating systems, reduce energy loss during heat transfer, and improve the economic benefits of pipeline networks. Therefore, it is necessary to innovate the applicability of their new pipeline network systems, and predict its energy consumption loss.
