Abstract: Refining and petrochemical enterprises have a huge number and variety of thermal insulation pipelines. Therefore, the management is difficult and inefficient. Through the development of hierarchical management system for pipeline insulation, the functions of pipeline insulation data query, hierarchical management and evaluation, energy consumption management and online operation status monitoring are realized. The system can provide auxiliary decision support for technicians and managers, screen the pipelines in urgent need of transformation, and make efficient use of transformation funds. The system was applied to screen 16 steam pipelines in a refinery, which were in urgent need of transformation. After the transformation, the energy-saving effect was remarkable. The system can achieve the all-round monitoring and management of pipeline insulation conditions, improve the management level of pipeline insulation, and achieve significant economic and social benefits in the aspects of energy-saving, environmental protection and safety.
