Buried polyurethane insulation of steam
|
Buried polyurethane insulation consists of three parts. (1) Pipe work: according to the technical requirements of the transmission medium were used pipe joints, seamless, double-sided spiral submerged arc welded steel pipe. (2) Thermal insulation layer: rigid polyurethane foam. (3) protective shell: high density polyethylene or fiberglass. Buried polyurethane insulation tubes are made of high density polyethylene outer protective layer of polyurethane rigid foam plastic pipe and pipe components. Insulation material density 60kg / m3 to 80kg / m3 rigid polyurethane foam, fully fill up the gap between the pipe and the casing, and has a certain adhesive strength, the steel pipe, the outer sleeve and insulation among forming a solid overall. Buried polyurethane foam insulation tubes with good mechanical properties and thermal insulation properties, generally the case may be modified by temperature or other insulating material combinations can be temperature 120 ℃ 180 ℃. Polyurethane insulation is widely used in liquid, gas pipeline network, chemical pipe insulation works in petroleum, chemical, central heating network, central air conditioning and ventilation ducts and municipal engineering. High temperature prefabricated buried pipe insulation prefabricated buried pipe insulation is a good insulation properties, plus safe, reliable, low cost project. Features high temperature pipe insulation prefabricated buried pipe insulation - Advantages 1 has high corrosion and water capacity, and lower total cost, according to an estimate, 2 control heating pipes, under normal circumstances can be reduced to 25% of project cost (using FRP protective layer) and 10% (high-density polyethylene protective layer) around. 2 low heat loss and save energy. Heat loss of only 25% of traditional pipe buried pipe insulation thermal conductivity 0.022kcal / mh ℃ hydrophobic rate 0.03kg / cm3 3 long life make the proper installation and use of network life expectancy of 30 - 50 years, and maintenance costs extremely low. 4 small footprint and fast construction conducive to environmental protection to reduce the amount of earth excavation for more than 50% reduction in civil engineering and concrete masonry units amount to 90% technical specifications insulation capacity Kg / m3 45-60 Thermal conductivity W / mk 0.016-0.024 use Temperature ℃ -90- + 120 obturator water absorption rate% ≥97 Kg / m2 ≤0.2 oxygen index h ≥26 compressive strength Mpa ≥200
