High Density Polyethylene (HDPE) insulation steel pipe is composed of working steel pipe, polyurethane insulation layer and polyethylene plastic outer protective pipe, which is used for insulation and cooling of indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical industry, medicine and long-distance transportation pipelines of petroleum.
HDPE Jacket pipe makes secure a waterproof, durability and UV-resistance of pre-insulated pipe. The high density polyethylene outer layer has good anti-corrosion, insulation performance. The rigid polyurethane foam is tightly bonded to the outer layer of the steel tube to prevent the infiltration of air and water, which can play a good role in anti-corrosion without considering the problem of adhesion to the anti-corrosion layer. The closed-hole ratio of polyurethane foam is over 92%, which is not only thermal insulation, but also can effectively prevent penetrating from water, moisture and a variety of other corrosive liquids and gases.
