摘要
Abstract
Taking PE-RT Ⅱ plastic pipelines as the research object,heat loss tests are performed on insu-lated and noninsulated PE-RT Ⅱ plastic pipes to ana-lyze their thermal insulation performance.The equiva-lent roughness of PE-RT Ⅱ pipes is calculated from testing data,and the dragreduction performance is ana-lyzed by comparison with steel pipes.With the same insulation and external protective layer,the overall thermal resistance of the insulation system for PE-RTⅡ pipes is 4.7%higher than that of steel pipes.The polyurethane foam layer is the main guarantee of ther-mal insulation performance for directly buried heating pipelines.Compared with steel pipes,PE-RT Ⅱ plas-tic pipes exhibit increasingly prominent drag-reduction performance as the flow rate rises.关键词
