Supply Buried polyurethane insulation products exhibited, [] GB Bohai polyurethane insulation pipe products Daquan Generally, buried pipe insulation, polyurethane pipe insulation, pipe insulation, etc. are often prefabricated high-density polyethylene material is precisely because of this material makes the buried insulating pipe with high mechanical strength and excellent corrosion resistance, and can protect the pipe during transportation, installation and use of the process, and so is not affected by other factors. Moreover, with the scientific and technological innovation and economic development, innovation buried insulating pipe will also find a new way out. Buried pipe insulation according to different insulation materials is divided into two: the first polyurethane insulation pipe, buried pipe insulation composite insulation materials, its structure is close to the pipe insulation and thermal insulation layer and the polyethylene jacket The polyurethane foam pipe insulation layer between the composite components. Because polyurethane foam molding can layer and the outer tube to heat to generate sufficient pressure to ensure the integrity of the composite tube, pipe insulation make this compound can be used for direct burial, this compound buried insulating pipe temperature +300 ℃. The second use of modified Niaopao ester hard as insulation layer, this rigid polyurethane foam with a similar, fully enclosed uniform foam blowing agent and the thermal conductivity of the formation of such tiny foam superior insulation performance, buried pipe insulation thermal conductivity less than 0.023W/mk, prefabricated pipe insulation tensile strength greater than 200Kpa, polyurethane insulation obturator rate greater than 97%, temperature 150 ℃ buried insulating pipe heat loss when less than 2%, the thermal deformation of less than 1 %, in line with the ASTM standard, suitable for handling not more than 150 ℃ heat medium, such insulation pipe insulation thickness is also divided by two series of the same specifications and ordinary pipe insulation can be suitable for different user requirements.
