Exceptional Wear, Impact, And Corrosion Resistance For Slurry, Dredging, And Material Transfer Systems
Uhmwpe pipes offer outstanding resistance to abrasion, corrosion, and impact, making them ideal for demanding slurry and dredging applications.
Ultra-High Molecular Weight Polyethylene (UHMWPE) pipes are advanced thermoplastic pipes engineered for abrasive and corrosive fluid transport in mining, dredging, chemical processing, and bulk material industries. With a molecular weight exceeding 2 million g/mol, UHMWPE offers exceptional abrasion resistance—up to 7 times greater than steel and more than 4 times that of conventional HDPE pipes.
Features a low friction coefficient, self-lubrication, and a non-scaling surface to reduce energy consumption in slurry transport systems and prevent clogging.
Maintains flexibility and mechanical strength from -269°C to +80°C, with excellent impact resistance even in extreme cold.
Lightweight design simplifies installation and handling, providing longer service life in transporting sand, coal slurry, tailings, fly ash, pulp, and chemical effluents.
Offers superior corrosion resistance, making UHMWPE pipes ideal replacements for metal pipes in dredging and mine backfilling applications.

Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.
With a molecular weight typically between 3.5 and 9.2 million g/mol, UHMWPE exhibits superior wear resistance, impact strength, and chemical stability, far exceeding conventional polyethylene or metal pipes in durability and performance.
Offers 15× the wear resistance of steel and 4× that of stainless steel, ideal for high-abrasion conditions.
Weighs 8× less than steel (specific gravity 0.93–0.95), lowering transportation and installation costs.
Excellent resistance to acids, alkalis, and organic solvents with zero corrosion in chemical environments.
The specifications of Ultra-High Molecular Weight Polyethylene (UHMWPE) pipes can vary based on the manufacturer, application, and specific requirements. However, here are some common specifications that are often associated with UHMWPE pipes:
