Alumina ceramic sleeve lined pipe bends are advanced wear-resistant pipeline fittings designed to handle the most abrasive and corrosive flow conditions, especially where directional changes occur—such as elbows and curves. These bends feature high-hardness alumina ceramic sleeves (92–95%) securely embedded into steel outer shells, forming a dual-layer structure for enhanced performance and durability.

They are widely used in thermal power plants, mining slurry systems, coal conveying lines, cement works, and chemical material pipelines, where they replace traditional steel, alloy, or rubber-lined bends that wear quickly under high-impact conditions.
