Anti-corrosion layer: protect the outer steel pipe to avoid corrosion of steel pipe, extend the service life of steel pipe.
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 protection steel pipe: protect the insulation layer from groundwater erosion, support the working pipe and can withstand a certain external load to ensure the normal work of the working pipe.
3. Polyurethane foam layer: to ensure the temperature of the medium, to ensure that the surface of the outer protective tube is maintained at normal temperature.
4. Barrier and reflection layer: to ensure that organic foam materials do 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: ensure the normal flow of the conveying medium.
Polyurethane insulation steel pipe has the best insulation, waterproof, anti-corrosion, insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, light capacity, high strength, simple and fast construction, not afraid of plant roots and other excellent characteristics, has become the construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors of insulation and insulation, waterproof plugging, sealing and other indispensable materials. Polyurethane insulation steel pipes are used for indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical and other industrial pipelines of insulation, cooling engineering, oil pipeline engineering, steam and other pipeline projects. Polyurethane insulation steel pipe can be directly buried in 0.6-1.2 meters of frozen soil layer heat loss than ordinary pipes can be reduced by more than 40%, the working life than other insulation and anti-corrosion materials increased by more than 3-5 times, the life can reach 30-50 years.
Polyurethane insulation steel pipe has good mechanical properties and thermal insulation properties, usually can withstand 120 ° C, through modification or combined with other thermal insulation materials can withstand 180 ° C.
