Polyurethane insulation structure and price

1: Buried polyurethane insulation: polyurethane insulation pipe buried pipe insulation, also known by the transport medium, working steel, polyurethane insulation, polyethylene plastic outer sheath tube, followed by combination of equipment out. Features: 1, lower project cost. 2, low heat loss and save energy. 3, anti-corrosion, insulation performance, long service life. 4, small footprint, and fast construction, favorable environmental protection. 5, safety. 2: Fiberglass insulation: fiberglass pipe insulation Buried by the transport medium steel, polyurethane rigid foam insulation and fiberglass reinforced plastic outer sheath (FRP) closely together. It has good mechanical strength and excellent corrosion resistance. Features: 1, with good physical properties, high strength steel, cast iron and plastic. Expansion coefficient of the glass tube steel roughly, only 0.5% of the thermal conductivity of steel, is a good thermal and electrical insulator. 2, good corrosion resistance, long life, up to 30 years. 3, low thermal conductivity, is 0.028W / mK, excellent insulation properties, temperature drop of less than 0.5 ℃ / km.
