Ultra-high molecular weight polyethylene (UHMW-PE) pipe is a new type of plastic pipe that is wear-resistant, impact-resistant, corrosion-resistant, non-absorbent and self-lubricating. It is widely applied across various fields:
Resists harsh acidic soil, seawater, and internal sulfur-containing oil. Handles high viscosity crude oil efficiently and improves pipeline transmission and lifespan.
Used for tailings water grouting filling, ground drilling, and high-pressure reinforcement to mitigate surface subsidence and improve project economics.
Transports highly corrosive media like strong acids, alkalis, brine, salt slurry, and raw salt in the chemical sector.
Transports sediment in dredging projects across rivers, lakes, ports, and docks.
Suitable for seawater transportation in seawater desalination systems.
Applied in sewage treatment, domestic water supply, and gas or natural gas transmission.
Processed into wear-resistant bearing bushes, sliding bearings, bushings, rollers, and gaskets to replace metal parts.
Hygienic, non-toxic, wear-resistant, and cost-effective pipeline solution preventing blockage during high-speed conveying.
Lining Technology: UHMWPE oil well lining pipe is an alloy material based on high molecular polymer. Lined tubing reduces sucker rod and tubing wear, limits downhole failures, improves anti-corrosion performance, and extends the pump inspection cycle and overall service life.
Molecular weight exceeds 2 million, yielding low sliding friction. Wear resistance is 6.6 times higher than alloy steel and 27.3 times higher than stainless steel.
Exhibits high impact toughness (GB1843 standard). Resists damage from severe external impact, internal overload, and high pressure fluctuations.
Saturated molecular structure prevents chemical corrosion. Remains stable in under 80% hydrochloric acid, 75% sulfuric acid, and 20% nitric acid.
Friction coefficient is only 0.219MN/m (GB3960). Excellent dry lubrication performance prevents wear and strain in dusty, sediment-heavy environments.
Maintains impact and wear resistance at -269°C. It is capable of stable, long-term operation within a temperature range of -269°C to 80°C.
Low friction and non-polarity prevent scaling even in media with a pH level above 9. Ideal for transporting crude oil and mud.
Boasts high fatigue resistance (over 500,000 cycles) and environmental stress cracking resistance (>4000h). Retains over 70% mechanical strength after 50 years buried.
Weighs only one-eighth of steel pipes, reducing labor. Safe, reliable, and convenient connection via welding or flanging without anti-corrosion treatments.
Features high energy and noise absorption, antistatic behavior, electronic shielding ability, non-absorption, and light specific gravity.
UHMWPE pipes offer exceptional wear resistance, high impact toughness, chemical corrosion resistance, self-lubrication, anti-scaling properties, and unique stability at extreme temperatures (from -269°C to 80°C).
It isolates the sucker rod from direct contact with the oil pipe using a low-friction anti-wear pair. System rotation and anchoring technologies are also implemented to guarantee uniform wear distribution and keep components properly tensioned.
Yes. UHMWPE is highly chemically stable and saturated, resisting strong acids and alkalis. Its non-polar surface and low friction coefficient effectively prevent scaling even when conveying fluids with a pH level above 9.
Buried UHMWPE pipelines can serve for approximately 50 years while maintaining over 70% of their mechanical properties due to their exceptional fatigue resistance and environmental stress cracking resistance.
No. UHMWPE pipes are very lightweight (about 1/8 of the weight of steel pipes), simplifying transportation and handling. They can be installed above ground or buried, and connected securely via flanged joints or welding without extra anti-corrosion coatings.
