Pipe Elbow Lining

Flotation machines wear their parts quickly. Our Flotation Wear Parts are essential spares for flotation equipment, including impeller covers, stators, rotors, and wear liners. These parts contact slurry and bubbles directly, enduring high-speed rotation and corrosion.

Product Introduction

5 to 10 Times Longer Life Than Unlined Pipes

Elbows wear faster than straight pipes. When material changes direction, it hits the wall hard, causing scratches, wear, and leaks. Our Pipe Elbow Lining solves this.

Installs inside steel or ceramic elbows
Absorbs impact directly, protecting the pipe
Lifespan 5–10 times longer than unlined elbows, 3–5 times longer than rubber-lined elbows
Fits coal, slurry, tailings, dust, and cement pipes
Pipe size range: DN50–DN800
Elbow angles: 45°, 90°, 180°, or custom

Centrifugal Casting for Even Thickness

Made from high-wear polyurethane (PU), optimized for high impact and abrasion.

Hardness: 75A–90A (ASTM D2240)
Abrasion loss: ≤25 mm³ (DIN 53516)
Temperature range: -40 °C to 100 °C
Resistant to acids, alkalis, and oils
Thickness: 5–10 mm, uniform thanks to centrifugal casting
Strong bonding with no bubbles
Ends can have flanges or clamp connectors
Tested: water pressure (1.5× working pressure, 30 min) and wear simulation

Smooth Inside, No Clogs

Key strengths:

Extremely wear-resistant

Abrasion loss ≤25 mm³ ensures 8,000–10,000 hours life on iron ore or coal slurry

Impact-resistant

PU absorbs shock; ceramic linings break, PU does not

Low friction & non-clogging

Surface friction <0.3; wet materials don't stick

Noise reduction

Working noise is 15–20 dB lower than metal pipes

Corrosion-resistant

High rebound, no leaks
