Experimental and Numerical Simulation Research on Underground Insulated oil Pipes
The density,hardness,compressive strength,thermal conductivity,and hydrophobic corrosion resistance of three insulation materials were tested in the laboratory.CHGB/MPE composite insulation materials were selected,and a finite difference method was used to establish a heat transfer model for insulation oil pipes,and their thermal performance was evaluated.the results indicate that the insulation performance of insulated oil pipes is positively correlated with the thickness of the internal insulation layer.
