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

introduction of polyurethane insulation steel pipe:

1. Anticorrosive layer: protect the outer steel pipe from corrosion and prolong the service life of the steel pipe.

2. External protection steel pipe: protect the insulation layer from groundwater erosion, support the working pipe and can withstand certain external loads to ensure the normal operation of the working pipe.

3. Polyurethane foam layer: to ensure that the medium temperature, to ensure that the surface of the outer tube to maintain normal temperature.

4. Barrier, reflective layer: to ensure that the organic foam material does not enter the inorganic hard high temperature resistant layer; reflect part of the heat of the high temperature resistant layer.

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

6. Drag reduction layer: ensure the thermal expansion and contraction movement of the working steel pipe.

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

Polyurethane thermal insulation steel pipe has excellent characteristics such as high-efficiency thermal insulation, waterproof, anti-corrosion, thermal insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, light capacity, high strength, simple and fast construction, and not afraid of plant roots. It has become an indispensable material for thermal insulation, waterproof plugging and sealing in industrial departments such as construction, transportation, petroleum, chemical industry, electric power and refrigeration. Polyurethane thermal insulation steel pipe is used for indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical industries, and other industrial pipelines, such as thermal insulation, cold insulation projects, oil pipeline projects, steam and other pipeline projects. Polyurethane thermal insulation steel pipe can be directly buried in 0.6-1.2 meters of permafrost. The heat loss can be reduced by more than 40% compared with ordinary pipelines. The working life is 3-5 times higher than that of other thermal insulation and anti-corrosion materials, and the service life can reach 30-50 years.
