Functional characteristics of steel insulating pipe with steel sleeve
Polyurethane steel insulating pipe, Jinan Haolin insulating material, has first-class consumer technology and many high-end experimental equipment. Our company has also introduced professionals who specialize in consuming polyurethane steel sleeve insulation pipe, and professional consuming polyurethane pipeline insulation material. It is a manufacturer integrating research, development, consumption and operation of polyurethane series products. Our company's secondary operation of polyurethane steel insulating pipe, in the polyurethane steel insulating pipe industry, good quality and low price concessions.
The prefabricated polyurethane insulation pipe is made up of the steel pipe, the polyurethane rigid foam insulation layer and the high density polyethylene sheath pipe. The product is mainly used for the urban central heating network, the petroleum delivery pipeline, the high cold area water delivery pipeline and the industrial pipeline project in the factory area. It is highly efficient thermal insulation, waterproof, anti-corrosion and application. It can be directly buried in 0.6-1.2 meters of frozen soil layer without trench laying. The heat loss can be reduced by 40% compared with the traditional technology. The service life is more than 3-5 times longer than other insulation and anti-corrosion materials. The service life can reach 30-50 years.
Functional objective of prefabricated polyurethane insulating pipe: All the functions of directly buried insulating pipe are excellent, and the treatment technology of shot blasting and rust removal on the surface of steel pipe and corona treatment on the outer and outer surface of protective pipe are strictly carried out, so as to further improve the bonding function of insulating pipe. The insulation layer material is rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which fully filled the gap between the steel pipe and the casing, and has certain bonding strength, so that the steel pipe, the outer pipe and the insulation layer can form a solid whole among the three.
Polyurethane foam has good mechanical function and adiabatic function. Under normal conditions, it can withstand temperatures of 120 degrees Celsius. After modification or combination with other thermal insulation materials, polyurethane foam can withstand temperatures of 180 degrees Celsius.
