Ultra-high molecular weight polyethylene UHMW-PE pipe are made of ultra-high molecular weight polyethylene raw materials with a viscosity average molecular weight of 3.5 million to 9.2 million. They are extruded under high temperature and high pressure by special machinery. They are widely used in blow filling, dredging, and mine tailings. Mine, ash and slag transportation and other fields.
Compare with existing plastic pipes, Wear resistant UNMWPE pipe has the most excellent wear resistance which is 4 to 7 times that of Q235 steel pipe and 2.7 times that of wear-resistant steel 16Mn. Therefore it increases pipe flow rate and improves the transmission efficiency of more than 20%. The working life of UHMWPE pipes is more than 3 times that of wear-resistant steel pipe.
Ultra High Molecular Weight Polyethylene (UHMWPE) pipes are ideal for slurry and dredging pipelines because of their high abrasion and wear resistance.
The low friction of UHMWPE pipes allows solid particles to slide easily over the surface, avoiding scaling and fouling.
The smooth inner surface of UHMWPE pipeline ensures low friction loss and high flow rate. UHMWPE pipe has great advantages to replace traditional metal pipes in delivering abrasive media.
UNMWPE Pipes
UHMWPE pipe is high pressure resistant and highly flexible. The compressive strength of UHMWPE pipe is 2 times to that of PE100 pipe and 2.5 times to that of PE80. UHMWPE pipes can withstand wide fluctuate of water pressure in the pipeline.
At the temperature of -70 ℃，UHMWPE pipe can work with normal mechanical performance. It is suitable for water supply and drainage in cold area.
Wear resistant UHMWPE pipe is self-lubrication and non-adhesive. Its coefficient of friction resistance is 0.009 while that of steel pipe is 0.013. With the same diameter, flow rate of UHMWPE pipe is larger than steel pipe, and with the same flow rate, UHMWPE pipe can save 25% energy.
Wear resistant UHMWPE pipe is greatly impact resistant which is 5 times that of HDPE pipe, 2 times that of PC pipe and 10 times that of PTFE pipes. With extraordinary impact resistance, UHMWPE pipe can withstand great water hammer impact when starting up pump.
UNMWPE Pipes
With roughness of 0.00022 and smooth pipe inner wall, it can efficiently avoid scaling without acid cleaning, which save a lot of maintenance cost.
With characteristics of corrosion resistance, low temperature resistance, non-scaling, no leakage, etc, UHMWPE pipe can work without extra anticorrosive coating, cleaning and maintenance which save more than 95% energy.
The manufacturing and processing of wear resistant UHMWPE pipe is low carbon and environment friendly with low emission of carbon dioxide which is 15% that of steel pipe and without discharge of wasted water, exhausted gas and waste residue which saves 20% energy compare with the traditional steel pipes.
With high toughness and elongation of no less than 350%, the UHMWPE pipe and the connection site will not crack when crust settling which maximally ensure to supply water normally.
