Sanmenxia best use of wear-resistant pipe pumping sand

Sanmenxia preferably wear pumping sand tubes are State-run pipe industry production ultra-high molecular weight polyethylene pipe 1, ultrahigh molecular weight polyethylene high impact resistance impact resistance and absorb impact energy ranks first in plastic, both external strong impact, or internal pressure fluctuations make it difficult to crack. Its impact strength of nylon 66 10 times, 20 times PVC, polyethylene four times. Especially at low temperatures, the impact strength but higher value. UHMWPE of this flexibility for the delivery system provides a safe and reliable protection. 2, high wear resistance in many pipe materials, ultra-high molecular weight polyethylene smallest friction coefficient, combined with ultra-high molecular chain is particularly long, so that the wear resistance of ultra high molecular weight polyethylene pipe in the delivery of various slurries than when steel, stainless steel tube 4-7 times higher than the PVC pipe and PE pipe about 10 times higher, greatly improve the life of the pipeline. 3, corrosion resistance, ultra high molecular weight polyethylene is based on a structure of saturated molecules, so its high chemical stability, in a certain temperature and concentration ability of a variety of highly corrosive media (acids, bases, salts) and organic Erosion of the solvent. 4, scaling UHMWPE self-lubricating and non-sticking coefficient of friction to a minimum. A special process to produce the inner wall of the pipe corrosion, abrasion resistance, no scaling, and therefore the flow resistance is small, long-term retention rate and flow unabated. Design of comparable steel pipe inner diameter is reduced by 15.4%. 5, weathering and aging resistance I produced a black modified ultrahigh molecular weight polyethylene pipe has excellent weather and aging resistance. On the one hand, because of ultra-high molecular chain unsaturated pipeline molecular chains few molecular weight; on the other hand, adding a special modifier, making ultra high molecular weight polyethylene pipe life greatly exceeds the ordinary polyethylene pipe. About a 60-year, high pipeline still maintain more than 70% of the mechanical properties. 6, optimum temperature wide long-term work at a temperature of -269 ℃ to 80 ℃. 7, used in fire retardant special industry environment, adding flame retardant modified, special processing technology manufacturing, overcome UHMWPE itself flammability, flame retardant properties. 8, light weight, ease of installation of this product is flexible, able to adapt to a variety of geological conditions, can be directly laid bend; flange connection, no insert sheet, connection quick and easy
