The outer layer is black polyethylene material, called the black jacket insulation tube.A high-pressure foaming machine is used to inject rigid polyurethane foam liquid into the cavity between the steel pipe and the outer protective layer at one time, and then the surface of the steel pipe is treated with polyethylene to form the outer protective layer. Polyethylene buried directly buried heat insulation pipe, high density polyethylene insulation pipe directly buried precast insulation pipe is made up of conveying medium steel tube, polyurethane rigid foam insulation layer and high density polyethylenene coat pipe, directly buried insulation pipe is mainly used for urban central heating network, oil transportation pipeline, high cold area water conveyance  pipeline and production area. Industrial pipeline engineering. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, the  infiltration of air and water can be isolated, and good anticorrosion effect can be achieved.
