Factory Direct Sale Cast Stone Lined Pipe
Cast Stone Lined Pipes are abrasion-resistant pipes with an inner lining made of cast basalt or synthetic stone composites, offering superior wear protection in slurry transport, ash handling, and mining applications. These pipes combine the durability of natural stone with engineered bonding systems for reliable performance in harsh environments.

Advantages
Extreme Abrasion Resistance – 5–10x longer lifespan than steel pipes in slurry applications.
Corrosion Resistance – Inert to acids, alkalis, and chemicals (pH 3–12).
Low Friction – Smooth inner surface reduces energy loss in material flow.
Thermal Stability – Withstands temperatures up to 450°C (basalt) / 300°C (synthetic stone).
Lightweight – Easier to install compared to steel-reinforced ceramic pipes.
Typical Applications
Cast stone lined pipe is used in industries where abrasion is the primary destroyer of piping:
Mining & Mineral Processing: Tailings lines, mill discharge, hydro-transport of ore, cyclone feed/underflow.
Coal-Fired Power Plants: Bottom ash slurry lines, fly ash transport (especially high-carbon/hot ash).
Steel Mills: Scale slurry lines, dust slurry transport.
Dredging: High-concentration sand and gravel lines.
Industrial Waste: Conveying abrasive industrial sludge.
