Polyurethane insulation steel pipe has good mechanical properties and thermal insulation properties

Introduction of polyurethane insulation steel pipe:

1. Anti-corrosion layer: protect the outer steel pipe to avoid corrosion of steel pipe, extend the service life of steel pipe.

2. Outer steel pipe: protect the insulation layer from groundwater erosion, support the working pipe and can withstand certain external load, to ensure the normal work of the working pipe.

3. Polyurethane foam layer: ensure the medium temperature, ensure the surface of the outer sheath pipe to maintain room temperature.

4. Barrier and reflection layer: ensure that the organic foam material does not enter the inorganic rigid high temperature resistant layer; reflect part of the heat of the high temperature resistant layer.

5. Inorganic rigid insulation layer: high temperature resistance, to ensure the interface temperature between the organic insulation layer, to ensure that the foam is not carbonized.

6. Resistance reducing layer: ensure the thermal expansion and contraction movement of the working steel pipe.

7. Working steel pipe: to ensure the normal flow of conveying medium.

Polyurethane insulation steel pipe has high efficiency insulation, waterproof, anti-corrosion, adiabatic, sound insulation, flame retardant, cold resistance, anti-corrosion, light capacity, high strength, easy and quick construction, not afraid of plant root thorns and other excellent features, has become an indispensable material for construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors such as adiabatic insulation, waterproof plugging, sealing. Polyurethane insulation steel pipe is used for various indoor and outdoor pipelines, centralized heating pipeline, central air conditioning pipeline, chemical industry, and other industrial pipeline insulation, refrigeration engineering, oil pipeline engineering, steam transmission and other pipeline engineering. Polyurethane insulation steel pipe can be buried in 0.6-1.2 meters of permafrost layer direct heat loss than ordinary pipeline can be reduced by more than 40%, working life than other insulation anti-corrosion materials to improve more than 3-5 times, life can reach 30-50 years.
