Defects in pipeline insulation layer
To enable the smooth flow of "three-high" crude oil with high wax content, high pour point and high viscosity in the oil pipeline, the oil products are usually heated at the oil transportation station to keep the temperature of the oil products above the pour point or at an even higher temperature. Considering energy conservation, consumption reduction, cost reduction and efficiency improvement, insulation measures are usually added to the outer shell of the oil pipeline. When the outer surface temperature of the normal insulation layer is close to the ambient temperature, it indicates good insulation, which can achieve excellent energy-saving and heat preservation effects.
