Performance comparison between insulated steel pipes and traditional pipes: Compared to traditional pipes, insulated steel pipes exhibit significant advantages in multiple aspects. In terms of energy-saving efficiency, the heat loss of insulated steel pipes is only 25% of that of traditional pipes, mainly due to the low thermal conductivity of its polyurethane foam layer, which is as low as 0.022 - 0.033W/(m・K). Moreover, the structure with a closed cell content of ≥92% effectively prevents heat transfer. Over long-term operation, it can save energy costs by more than 30%, significantly reducing energy consumption. In terms of overall cost, the direct burial installation method of insulated steel pipes reduces earth excavation by more than 50% and saves 90% of concrete usage, resulting in a reduction of the overall project cost by 10% - 25%.
