Mine supply pipe 6 on the wear resistance is 4-7 times stronger than steel, polyethylene, polypropylene, 10 times, 2.3 times the PE of a class of small particles of fly ash conveying slurries better. Resistance to environmental stress cracking, anti-carved capacity ranks first in all kinds of plastic, which is more than 10 times the PE100, the lower the ambient temperature, impact resistance stronger impact strength at room temperature. Contact: Li phone number: 155 1795 7863 130 14741272 QQ: 2778205341 high wear pipeline: http: //www.grcggc.com/ steel lined pipes: http: //www.60692521.com/ Address: Luoyang Mengjin County Municipal Airport Industrial Park, true and false identification method of ultra-high molecular weight polyethylene: a specific gravity method: pure supply pipe 65 with the mine ultra high molecular weight polyethylene (UHMW PE) products, the proportion between 0.93-0.95, more than water, light, can float on water. Filling material back ultra-high molecular weight polyethylene (UHMW PE) products, its share will change. Second, the temperature method: true ultra high molecular weight polyethylene products, at 200 degrees Celsius is not melted, will not be deformed, but become soft. Filling material back ultra-high molecular weight polyethylene pipe, at 200 degrees Celsius there will be deformed. Third, the visual method: true ultra-high molecular weight polyethylene pipe surface smooth, uniform, smooth, shiny black and very uniform density section, filling material back ultra-high molecular weight polyethylene pipe surface roughness, and the color gray, the color of dark , cut uneven density. Fourth, flanging method: using a real mine supply pipe 65 UHMWPE pipe flange end face rounded, uniform, smooth filling material back ultrahigh molecular weight polyethylene pipe flange end surface cracks, and in turn heating side dregs phenomenon occurs when five, another way is to go to the manufacturer's plant to observe the production of pure high molecular weight polyethylene pipe per hour can produce 20 --- 30cm in length, if you find the tube production speed too, indicating that not pure UHMWPE pipe. Sixth, look at manufacturers Qualifications: see manufacturers have no raw material provided by the manufacturer of ultrahigh molecular weight polyethylene pipe inspection reports Inspection reports and related molecular testing. Seven, allow manufacturers to provide samples, to get the relevant departments to do their own tests to see if the molecular weight of the test report is not more than 2 million. If that is true, whether it false.
