Polyurethane buried thermal insulation pipe, full name: high density polyethylene plastic outer protection polyurethane foam prefabricated buried thermal insulation pipe, by the transmission medium of the working steel pipe, polyurethane insulation layer, polyethylene plastic outer protection pipe, through the equipment in order to the outside combined and become. Polyurethane insulation pipe has a light weight, high strength, insulation, sound insulation, flame retardant, cold, corrosion, non-absorbent, easy and fast construction and other excellent features, has become the construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors of adiabatic insulation, waterproofing, leakage, sealing and other indispensable materials.
Small thermal conductivity:
The thermal conductivity of polyurethane foam is the lowest among the thermal insulation materials, so the heat loss of the material can be reduced to the minimum.
Waterproof, anticorrosive, age-resistant.
As the closed cell rate of polyurethane foam reaches more than 92%, therefore, using polyurethane foam as the thermal insulation layer of directly buried pipeline can not only play the role of thermal insulation, but also effectively prevent water, moisture and other kinds of corrosive liquids and gases from penetrating, and prevent the breeding and development of microorganisms.
Polyurethane buried pipe insulation with its excellent performance, convenient construction and long service life and popular.
