Combining steel strength with UHMWPE durability for industrial-grade abrasion and corrosion resistance.

UHMWPE (Ultra-High Molecular Weight Polyethylene) lined steel pipes are high-performance composite pipes designed for tough industrial conditions. The steel shell provides structural integrity, while the inner UHMWPE layer—bonded via sintering, mechanical interlocking, or adhesive—offers superior abrasion and corrosion resistance.

With a lining thickness of 8–20 mm, UHMWPE pipes are ideal for conveying abrasive slurries, corrosive fluids, or high-pressure media in mining, dredging, chemical processing, and water treatment.

What is UHMWPE?

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.

Superior Wear Resistance

Offers 15× the wear resistance of steel and 4× that of stainless steel, ideal for high-abrasion conditions.

Lightweight Design

Weighs 8× less than steel (specific gravity 0.93–0.95), lowering transportation and installation costs.

Chemical Resistance

Excellent resistance to acids, alkalis, and organic solvents with zero corrosion in chemical environments.

UHMWPE is more durable and abrasion-resistant than HDPE. Its long polymer chains provide superior resistance to wear, allowing it to last up to 10 times longer than HDPE in high-wear applications. However, HDPE is easier to machine and weld, making it suitable for applications requiring fabrication.

Low melting point: Not suitable for high-temperature applications.
Limited UV resistance: Degrades under prolonged sunlight exposure.
Difficult to bond: Requires special adhesives or surface treatments.
Limited wear resistance in abrasive environments: Less effective than ceramics or metals.
Not ideal for high-load bearings: Low modulus may cause deformation.
Difficult to machine: Needs special tools due to high molecular weight.
Sensitive to oxidation: Degrades mechanical properties at elevated temperatures.
Water absorption: Can affect dimensional stability and strength.

Despite these drawbacks, UHMWPE remains useful for applications where its unique combination of durability and chemical resistance is advantageous.

The better material depends on the application:

UHMWPE: Ideal for industrial settings where friction, impact, and wear resistance are critical.
HDPE: Better for projects requiring welding or fabrication, such as chemical storage tanks or 3D-printed parts.

High abrasion resistance: Withstands significant wear, ideal for abrasive material transport.
Excellent impact strength: Absorbs high energy without damage.
Low coefficient of friction: Reduces friction and wear, lowering pumping costs.
Good chemical resistance: Suitable for various industrial chemicals.
Lightweight: Easier to install and transport than steel.
Low maintenance: Resists scaling and fouling.
Wide temperature range: Performs well in low to moderate temperatures.

Dredging and mining: Transporting slurries, sand, gravel.
Chemical processing: Transporting corrosive and abrasive chemicals.
Water and wastewater: Used in treatment facilities.
Food processing: FDA/USDA-approved grades used safely in food industries.
Construction: Used in tunnel escape routes and impact-resistant applications.

Low melting point: Unsuitable for high-temperature use.
Creep: May deform under long-term stress.
Cost: Higher initial cost compared to some alternatives.

Surface finish: Should be smooth, uniform, and bright.
Density: Pure UHMWPE floats in water; lower quality sinks.
End finish: Smooth, round ends with good verticality.
Flanging: UHMWPE can be flanged by heating; HDPE requires a stub end weld.

Yes, UHMWPE is available in several grades, each tailored for specific use cases:

Virgin UHMWPE: Standard grade for general use.
Reprocessed UHMWPE: Budget option for less critical applications.
Anti-static UHMWPE: Prevents static buildup.
Tivar: Designed for maximum wear resistance.
Tivar DrySlide: Combines anti-static and self-lubricating properties.
