Cast Basalt Tile Lined Pipe

Interlocking cast basalt tiles inside steel pipes ensure outstanding resistance to wear, corrosion, and high temperatures in harsh industrial flows.

Cast basalt tile lined pipes are advanced composite piping systems designed to withstand the most abrasive and corrosive industrial environments. These pipes feature a robust carbon steel shell internally fitted with interlocking cast basalt tiles that form a smooth, wear-resistant lining. The basalt tiles, formed from naturally occurring volcanic rock, are cast at high temperatures (over 1300°C) and precisely cut for seamless fitting.

Key Features:

Exceptional Abrasion Resistance: With a Mohs hardness of 7–8, basalt tiles provide a long-lasting internal surface that resists aggressive wear from particles such as ash, slag, ore, and sand.
Chemical Corrosion Protection: Cast basalt is naturally resistant to acids, alkalis, and chemical fumes, ensuring pipe longevity even in chemically aggressive flows.
High-Temperature Stability: Suitable for continuous operation in environments up to 450°C, making it ideal for hot ash or exhaust dust transfer.
Smooth Internal Surface: The polished basalt lining minimizes flow resistance, reduces buildup, and promotes efficient transport of materials.
Modular & Flexible Design: Customizable for various pipe diameters (DN50 to DN800+), with options for flanged, welded, or socket connections.
Extended Service Life: Typically lasts 5–10 times longer than steel or rubber-lined alternatives in comparable service conditions.

Key Advantages

8–15× Longer Service Life

Far exceeds unlined steel, AR plate and most ceramic linings in severe sliding abrasion.

Superior Corrosion Resistance

Resists almost all acids, alkalis and saline solutions (except HF).

High Temperature Tolerance

Continuous service up to 350–450 °C (grade dependent).

Low-Friction Smooth Surface

Prevents material adhesion and reduces pressure loss & energy consumption.

Easy Installation & Maintenance

Steel outer shell allows normal welding. Damaged sections can be cut out and replaced individually without dismantling the entire line.

Typical Applications of Cast Basalt Tile Lined Pipe

Cast basalt lined pipes (also known as玄武岩铸石衬里钢管) offer exceptional abrasion resistance, corrosion resistance, and smooth flow characteristics, making them ideal for hydraulic & pneumatic conveying of abrasive slurries in medium-impact environments.
