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 pe water pipeline construction, and pipe wall thickness was significantly lower than HDPE pipe. Invention and use of this new technology pipeline PSP has more than eight years pe water supply wholesale, widely used in many projects in China and internationally. Steel mesh skeleton plastic composite pipe insulation recommendations: hot water pipes running low temperature heat loss is small pe water pipe material, and the heat capacity of water is relatively large, so the 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 holding in an investment account for a large proportion or process allowed when the temperature can drop to allow thermal 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 polyethylene pipe and pipe fittings products company leading steel mesh skeleton polyethylene pipe and fittings (SRTP), with the current domestic industry leading level, the company has the industry standard CJ / t189-2007 and CECSl81: 2005 two members of the writing group, plastic pipe, fittings product design expert three people registered at the national level construction division 2, plastic molding and auxiliary machinery designed to process high abrasive intermediate professional and technical staff of 15 people, The company can independently SRTP product development production, engineering design, construction and after-sales support for integrated projects, namely EPC engineering, Industrial and R & D pipeline is a combined set of specialized production, personnel training, technical services coordinated development The modern enterprise. The company successfully developed dn200 following 5.OMpa, dnl40 following 6.OMpa / 8.OMpa steel mesh skeleton polyethylene pipe and supporting connectors, broke through the bottleneck of the original industry standard for the maximum pressure 3.5Mpa. The company's products with its unique antiseptic, wear-resistant, high temperature resistance, cold, pressure, creep resistance, good stability, easy installation, and gradually replace all kinds of metal and plastic pipe fittings are widely used in petroleum chemical, gas, water, mining, marine transportation and other fields. pe water pipe prices, smooth building materials (certified), Fuzhou pe water pipe Ltd Dongguan City unimpeded by building materials.
