Centrifugal glass wool pipe shell specialized for various types of pipes (including: insulation of refrigeration, hot water, steam) system, can work properly -4 ℃ -454 ℃ ambient temperature, exposed or covered. As the sleeve of this material with a waterproof, anti-corrosion, not moldy, protozoa characteristics, can effectively prevent condensation and prevent pipe freeze, for civil construction, heating pipes, air conditioning, and refrigeration equipment and insulation. Insulation, energy-saving effect can be increased by 15-30%. This product is glass wool applying a resin binder, and heating solidified into a tubular insulation materials, the surface can be pasted aluminum foil, with a moisture-proof, radiation characteristics. Bulk density: 30 to 80 kg/m3 tube shell diameter: ф22 to 1220mm thickness: 30mm to 100mm Usage: mainly used in petroleum, chemical, electric power, industrial heating, civil heating insulation, cold
