Detailed introduction of "Ziyang prefabricated direct buried thermal insulation pipe DN400/426 polyurethane rigid foam prefabricated pipe"
Ziyang Prefabricated Directly Buried Insulation Pipe DN400/426 Polyurethane Rigid Foam Prefabricated Pipe Advantages and Features of Three Prefabricated Directly Buried Insulation Pipes: 1. Reduce the project cost. According to the calculations of the relevant departments, the direct-buried insulation pipe double-pipe heating pipeline can generally reduce the project cost by about 25% (using glass fiber reinforced plastic as the protective layer) and 10% (using high-density polystyrene as the protective layer). 2. Low heat loss and energy saving. The thermal conductivity of the high temperature prefabricated directly buried insulation pipe is: λ
