Buried polyurethane foam insulation heating pipe specifications / price

Buried polyurethane foam insulation heating pipe specifications / price I produced the high-density polyethylene jacket pipe, overall performance, strict implementation of CJ / T114-2000 industry standards, work steel pipe outer surface and the outer casing of shot blasting process the inner tube surface corona treatment process to further improve the insulation performance of the Trinity. Life of up to 30 - 50 years, proper installation and use can make the pipe network maintenance costs low. Polyethylene outer sheath tube made of high-density polyethylene material, it can ensure the pipe from external factors caused damage in transportation, installation and use. Good insulation properties, thermal insulation effect than other insulation increase 4-9 times, the heat loss is only 25% traditional pipe, long run can save a lot of energy, significantly reduce energy costs, insulation material density greater than 60㎏ / m3 of rigid polyurethane foam, with good mechanical properties and thermal insulation properties, usually can be temperature 120 ℃, by modification or in combination with other insulation materials can be temperature 180 ℃. Foam sufficient to fill the gap between the pipe and the outer protective tube, and has a certain viscosity, the steel pipe, tube and the outer jacket insulation three form a solid overall. The products are widely used in urban central heating and refrigeration engineering, energy-saving effect is remarkable, easy construction and installation, with good economic and social benefits. Highly waterproof and corrosion resistance, without laying pipe trench can be directly buried in the ground or soil, construction easily and quickly, and lower total cost, small footprint. At low temperatures also have good corrosion resistance and impact resistance, it can be directly embedded in the permafrost. Polyethylene jacket with high-density polyethylene material with high mechanical strength and excellent corrosion resistance. It can ensure the pipe from damage caused by external factors in the transportation, installation and use. Low-temperature plasma generated by the discharge electrode tip within the outer protective layer of polyethylene surface corona treatment, after corona treatment within the outer jacket pipe surface tension of 50 dyne / cm or more, so that the outer protective layer of foam insulation between the tubes The shear strength was significantly enhanced. To ensure the overall quality of the tube, extending its life has meaning can not be ignored. Polyurethane insulation advantages: thermal insulation field joints shall only be carried out after pressure test, the insulation layer has a foam-insulation tile construction and construction of two ways, no matter what method of construction uses, can not appear the annular space, crack, off layer and other defects, the protective layer has a variety of practices (such as high density polyethylene and fiberglass protective layer), but they must ensure the integrity of joints, tight, waterproof. Because Pan Huailiang insulation rigid polyurethane foam insulation prefabricated buried pipe insulation foam intimately bonded in the steel skin, cut off from air and water infiltration, can play a good anti-corrosion effect. While its foaming holes are closed, water absorption is small. High density polyethylene shell, fiberglass shell have good anti-corrosion, insulation and mechanical properties. So work hard to be outside steel jacket of air and water erosion. As long as internal quality pipeline deal, but compared with the same length of straight pipe joints, weld length of 30 products are widely used in flammable and non-flammable fluid pipes and boilers, steel structures. Seamless steel pipe, also known as hot-rolled seamless steel pipe and hot-rolled steel. Fiber felt by the high temperature insulation, strength spiral welded pipe is generally higher than the Longitudinal, can narrow the larger diameter pipe billet students can also use the same width of the billet production of different pipe diameters. Tension seamless steel pipe seamless steel pipe production process is important is reducing tension through to complete the process of reducing rolling process is a continuous hollow base material without mandrel. Ultra-buried pipe insulation steel jacket pipe work from the inside, the outer protective pipe and the intermediate insulating layer. Work blasted steel two coats of rust. Prefabricated buried pipe insulation high temperature high pressure hot-rolled seamless steel pipe for medium temperature 350 ℃, pressure corrosion resistance, high coating strength, not destroy seamless elbow elbow pipe for a pipeline at the corner. The largest proportion was about the whole tube used in the piping system. Typically the thickness of different materials or choose a different bend forming process, commonly used in manufacturing processes are seamless elbow hot push forming, stamping, extrusion. Buried polyurethane foam insulation heating pipe specifications / price polyurethane insulation classification is very complex, generally in accordance with people's habits have several ways to look at, 1. In accordance with its transmission medium temperature can be divided into: normal polyurethane buried pipe insulation, high temperature polyurethane buried pipe insulation, cryogenic polyurethane buried pipe insulation; 2. The outer sheath can be divided into: the glass steel outer sheath polyurethane buried pipe insulation, high-density polyethylene outer sheath polyurethane buried pipe insulation, steel outer sheath of polyurethane insulation Buried pipes and other buried insulating outer sheath tube; 3. different transmission media there are many: such as water supply pipe manufacturers Hebei polyurethane insulation, high temperature polyurethane insulation, use of steam for Steam Buried polyurethane composite prefabricated pipe insulation, the use of oil buried rigid polyurethane foam insulation pipe corrosion and so on. There are many called as polyurethane pipe, polyurethane prefabricated pipe, buried prefabricated polyurethane tube, polyurethane jacket pipe, prefabricated buried pipe insulation, prefabricated buried pipe insulation and so on.
