Polyethylene pipe - smooth licensing HDPE (High Density Polyethylene) PEl00 environmental water pipe imported raw materials, according to GB / Tl3663 standards. Polyethylene pipe products have good weldability, resistance to environmental stress cracking resistance and resistance to rapid crack resistance, and its performance has reached international standards and national standards. To solve a long-term problem in China's water supply network and water in the process of secondary pollution problems steel mesh skeleton pipe price, and "Drinking Water" Target steel mesh skeleton tube construction, city water pipe can be widely applied, residential and commercial building water supply system. Factory outlets] polyethylene pipe Features: 1 health is good, no heavy metal additives, no scaling, no bacteria, solving the secondary pollution of drinking water, in line with GB / T17219 safety evaluation requirements. 2 excellent corrosion resistance, excellent abrasion resistance, flexibility Haonai impact, material stability aging up to 50 years of normal use. 3 reliable connectivity, easy construction, smooth wall flow, engineering and lower total cost. 4 unique fusion welded and Butt, hot melt technology enables interface plug the pipe body strength than to ensure the safe and reliable interface, which can be applied to trenchless crossing, river tube. Steel mesh skeleton plastic composite pipe, tube called PSP, is the use of high-strength steel wire coated after processing the existing wound HDPE pipe, the pressure performance than HDPE pipe has significantly enhanced, such as the PSP pipeline dn110 maximum pressure can reach 3.5Mpa, and pipe wall thickness was significantly lower than HDPE pipe. Invention and use of this new technology pipeline PSP has over eight years of history, is widely available in China and many international projects. Steel mesh skeleton plastic composite pipe insulation recommendations: small low temperature hot water pipes running heat loss and heat capacity of water is relatively large steel mesh skeleton tube, so water temperature drop is small, generally do not allow the temperature drop conditions by calculation. When the PSP ≥315mm nominal diameter pipeline, the proposal recommended maximum heat loss calculations. ? When the time accounted for a large proportion of the insulation or steel mesh skeleton process allows pipe manufacturers in an investment, according to the allowable temperature drop make insulation thickness calculations. At this point, steel mesh skeleton plastic composite pipe insulation thickness is slightly less than the thickness of pipe insulation, it should be checked whether the GB4272 in heat loss provisions;? Outdoor laying, seasonal operation, the external ambient temperature Ta take years running average maturity average temperature. ? When there are technical requirements, the external ambient temperature Ta values ??should be the most unfavorable conditions. ? Buried in the soil, when the center of the pipe is greater than twice the depth of the outer diameter of pipe insulation, the ambient temperature shall be taken as the natural center of the pipe buried in the depths of the soil temperature; when the center of the pipe is less than twice the depth of the outer diameter of pipe insulation, ambient temperature Preferably natural soil surface temperature. More than four times the depth of the pipeline proposal insulation outside diameter steel mesh skeleton composite pipe | steel mesh skeleton tube | Dongguan City unimpeded flow of building materials from the building materials Limited.
