Henan pumping sand tubes refers to ultra high molecular weight polyethylene pipe characteristics (1) wear ranks highest in plastic, carbon steel, stainless steel, 7 to 10 times; (2) the impact strength of plastic in the first column, 2 times for PC , ABS 5 times, and can be maintained at liquid nitrogen temperature (-196 ℃); (3) self-lubricating, anti-adhesion, non-fouling, low friction coefficient, with polytetrafluoroethylene (PTEE) comparable; ( 4) the value of the highest impact energy absorption in all plastics, and possessed a silencer; good (5) chemical stability, in a certain range of temperature and concentration ability of various corrosive media and organic media; (6) good low temperature resistance at liquid helium temperature (-269 ℃) remain ductility; (7) excellent compressive strength, resistance to environmental stress cracking resistance, resistance to rapid crack resistance; (8) health, non-toxic, can contact the Food and Drug . Working pressure: PN0.6-2.6MPa Flange Standard: figuring method UHMWPE pipe on HG20593-97 genuine market standards. First, the proportion of law: the proportion of pure ultra-high molecular weight polyethylene (UHMW-PE) products between 0.93-0.95, lighter than water and can float on water; add back fill material ultra high molecular weight polyethylene (UHMW-PE) product, its specific gravity will change (increase). Second, the temperature method: pure ultra-high molecular weight polyethylene (UHMW-PE) products at 200 degrees Celsius is not melted, not deformed, but become soft; add back fill material ultra high molecular weight polyethylene (UHMW -PE) products, at 200 degrees Celsius there will be deformed. Third, the visual method: pure ultra-high molecular weight polyethylene (UHMW-PE) products smooth surface, uniform, smooth, shiny black; filler material added back ultra high molecular weight polyethylene (UHMW-PE) products, surface roughness, and color gray, dark color. Fourth, flanging method: pure ultra high molecular weight polyethylene (UHMW-PE) products flange end face rounded, uniform, smooth; add back fill material of ultra high molecular weight polyethylene (UHMW-PE) products flange end surface cracks, and the dregs phenomenon occurs when heating flange.
