Abstract: This paper mainly discusses the insulation structure design and insulation material selection of petrochemical pipelines. Through the performance analysis of commonly used insulation materials, it is proposed that the selection of insulation materials should comprehensively consider factors such as thermal conductivity, service temperature range, engineering cost, and energy-saving benefits. Taking a steam pipeline of a petrochemical enterprise as an example, different insulation design schemes are compared. The results show that the use of new insulation materials with lower thermal conductivity and composite insulation structures can not only reduce the insulation thickness of the pipeline and lower heat loss but also have better life cycle costs and social benefits.
