The steam pipe network has the characteristics of high temperature and large consumption of transmission medium. There is large space for optimization in the heat loss of pipeline and the economic loss caused by it. The selection of advanced and efficient insulation materials and structure and application of advanced insulation technology are the effective ways for enterprises to save energy and create efficiency. This paper summarizes the commonly used thermal insulation materials and their research progress, introduces the basic experimental research or steam pipe network optimization and transformation carried out by different oil field mining companies and refinery enterprises, and the results show that aerogel silicate composite thermal insulation materials have better insulation performance and long-term economy than traditional thermal insulation materials, and have gradually been widely applied.
