The raw materials of yellow jacket insulation steel pipe mainly include seamless steel pipe and seamless steel pipe. The commonly used heat preservation material of yellow jacket polyurethane heat preservation pipe is rigid polyurethane foam plastics, the applicable temperature is - 185 - 120 C. In order to improve its strength, a layer of high density polyethylene (HDPE) is added outside the insulation layer to form a composite data structure to avoid the infiltration of open water into the insulation layer. Yellow jacket insulation pipe structure mainly includes working steel pipe layer, polyurethane insulation layer and high density polyethylene maintenance layer. One of the outer layers is covered by black or yellow polyethylene plastic materials prefabricated to a certain wall thickness. Black jacket insulation pipe is called black jacket insulation pipe, yellow jacket insulation pipe is called yellow jacket insulation pipe. Its function is to maintain the polyurethane insulation layer from the destruction of mechanical hard objects, and the second is anti-corrosion and waterproof.
The yellow jacket polyurethane foam insulation tube foam has good mechanical properties and insulation polyurethane insulation pipe application: polyurethane insulation pipe for indoor and outdoor pipes, central heating pipes, central air-conditioning pipe, chemical industry, and other industrial pipelines insulation and cold insulation works. Overview? Polyurethane foamed insulation pipe has been developed rapidly as an excellent thermal insulation material since the birth of polyurethane synthetic data in the 1930s, and its application scope is becoming more and more widespread. It is also widely used in various heating, refrigeration, oil transportation, steam transportation and other pipelines because of its cumbersome construction and remarkable energy-saving and anticorrosive effect.
The Yellow lined thermal insulation steel pipe directly buried prefabricated heat preservation 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 in the urban central heating network, the petroleum delivery pipeline, the cold water pipeline and the industrial pipeline project. It has the characteristics of high efficiency insulation, waterproof, antisepsis and construction, and is not afraid of plant root thorn. Advantages: construction without trench laying, can be directly buried in 0.6-1.2 meters of frozen soil layer, heat loss can be reduced by 40% compared with traditional technology, service life is more than 3-5 times higher than other insulation and anti-corrosion materials, and service life can reach 30-50 years.
