Impact Analysis of Three Types of Insulation Materials Cold Heat Transfer in the Pipeline

Abstract:

The good and bad effects of cryogenic equipments and pipe cold directly affect the energy consumption of the device as well as light hydrocarbon production. Therefore, the low temperature pipeline laying cold layer is necessary to analyze the cold material impact on the structure of the heat transfer of cryogenic piping cold, it can be able to provide a scientific basis for the future related to the transformation of low-temperature device and pipes. Through the establishment of the low-temperature piping cold heat transfer model, analyzing the impact of different pipeline medium temperature, cold material under low temperature piping cold heat transfer. The results show that : (1) Under the conditions of the same cold thickness ,the temperature of the medium in the pipe decreases , the heat flux becomes large , the cold loss becomes larger ; ( 2 ) Same medium temperature and the thickness of the cold , the cold effect of the insulation material order LT> polyurethane> foam glass .
