Product Overview
Ultra-High Molecular Weight Polyethylene (UHMW-PE) pipe is a new type of engineering plastic wear-resistant pipe extruded at high temperature with ultra-high density polyethylene (molecular weight 3.5-7.5 million). It boasts the best comprehensive performance among industrial polymer pipes, featuring super wear resistance, ultra-low friction, high impact resistance, low temperature resistance, corrosion resistance and anti-scaling performance. Its wear resistance is 4-7 times that of ordinary carbon steel, and its impact resistance ranks first among plastic pipes. It is widely used for conveying slurry, sediment, particles and corrosive media, effectively solving common problems of traditional metal pipes such as wear blockage, corrosion cracking and low-temperature brittleness.
Product Structure
Integrated homogeneous solid structure without delamination, with uniform and stable overall performance. Custom flange, steel lining and cladding structures are available.
• Homogeneous Polymer Main Layer：Integrally formed with high-purity UHMW-PE raw materials. The intertwined ultra-long molecular chains ensure uniform wear resistance, impact resistance and toughness, no weak areas, no deformation or cracking under long-term high-pressure conveying.
• Optional Steel Protective Layer：Custom outer steel casing for harsh working conditions, combining the wear & corrosion resistance of plastic and the pressure & impact resistance of steel pipes, suitable for complex outdoor and buried working conditions.
Reinforced Connection Structure：Integral injection molding flange with no splicing gaps, equipped with anti-corrosion flange gaskets, featuring high sealing performance to avoid slurry leakage and interface scouring.
Product Advantages
• Super Wear Resistance & Long Service Life: The unique ultra-long molecular chain structure provides far better wear resistance than steel pipes and ordinary PE pipes. Its service life is more than 4 times that of carbon steel pipes under strong scouring conditions of tailings and sediment, greatly reducing replacement and maintenance costs.
• Self-lubrication & Anti-scaling for Efficient Conveying: The friction coefficient is only 0.07-0.11 with near-zero friction. The inner wall avoids material adhesion, sludge accumulation and scaling, ensuring stable flow rate for long-term operation and reducing equipment energy consumption without frequent pipe cleaning.
• Excellent Low Temperature Resistance & High Toughness: It remains non-brittle and non-deformable at an extreme low temperature of -80℃, operating stably in northern winter, outdoor buried and underwater environments, completely solving the low-temperature freezing cracking problem of metal pipes.
• Strong Corrosion Resistance for Complex Media: Stable chemical properties resist acid, alkali, salt spray and sewage corrosion without rust or oxidation, suitable for complex working conditions such as chemical corrosive slurry, mine tailings and seawater transportation.
• Light Weight & Easy Construction: The weight is only 1/8 of steel pipes. No large equipment is required for handling and installation. It can be cut, welded and butt-connected arbitrarily with short construction period and low engineering cost.
• High Impact & Aging Resistance: Excellent toughness resists high-speed impact of stones and large-particle materials. With UV and aging resistance, its outdoor service life can exceed 15 years.
