Wear-resistant materials such as alumina ceramic, silicon carbide, and cast basalt are selected based on specific industrial needs and operational scenarios. These materials are engineered to combat abrasion, corrosion, high temperature, and chemical attack, extending equipment service life and reducing maintenance.

Typical applications include power plants handling fly ash and bottom ash, mining slurry pipelines transporting abrasive ores, cement plants processing raw materials, and chemical factories requiring corrosion-resistant piping. Special scenarios such as pneumatic conveying, high-pressure slurry transport, and extreme temperature environments demand customized linings and pipe designs.

By leveraging advanced materials and tailored engineering, industries achieve optimal performance and cost-efficiency, addressing their unique wear and corrosion challenges effectively.
