    This paper analyzes the steady thermal state of PIR LNG cryogenic pipeline insulation structure using ANSYS Workbench software and studies the numerical simulation of PIR internal temperature changes with the thickness of insulating layer by the method of coefficient of thermal conductivity. The relationship between the internal temperature of PIR cold insulation layer and the thickness of cold insulation layer is then obtained. The results of the research provide a theoretical basis for cold structure optimization of LNG pipeline.
