Verschleiß feste Aluminiumoxid-Keramik ausgekleidet Stahlrohre und Ellbogen für den Material transport

Wear-resistant alumina ceramic lined steel pipe is a composite material widely used in heavy-wear industrial applications. Its core design concept is to combine the toughness of steel with the hardness of ceramic to achieve ultimate wear resistance.

Wear-resistant ceramic-lined pipe combines the high hardness, wear resistance, and corrosion resistance of ceramic with the machinability, weldability, and high strength of steel. It offers advantages such as high wear resistance, light weight, easy processing, and flexible on-site installation.

Wear-resistant alumina ceramic-lined steel pipe typically consists of three components:

1. Outer steel pipe: Typically carbon steel or seamless steel pipe. This provides the overall mechanical strength and toughness of the pipe, withstanding operating pressures, impacts, and installation stresses.
2. Inner lining: Made of 95% or higher alumina (Al₂O₃) ceramic. This layer provides extremely high hardness and wear resistance, and is a key layer for directly resisting material erosion.
3. Bonding layer: The ceramic layer is securely attached to the inner wall of the steel pipe through a special process.

Compared to traditional metal wear-resistant pipes (such as wear-resistant alloy steel and bimetallic composite pipes), ceramic-lined pipes offer the following significant advantages:

Wear-resistant ceramic-lined pipes are specifically designed to address severe wear issues and are widely used in industrial pneumatic or hydraulic conveying of abrasive materials:

• Thermal power plants: pulverized coal conveying pipelines, ash handling systems (fly ash, bottom ash), and limestone powder conveying pipelines.
• Coal and mining: Tailings conveying, concentrate conveying, coal slurry pipelines, and underground backfill pipelines.
• Steel and metallurgy: Sinter dust conveying, coal injection pipelines, and dust removal pipelines.
• Cement industry: Pneumatic conveying pipelines for raw meal, clinker, and cement after grinding.
• Chemical industry: Conveying abrasive chemical raw materials and products.
• Mechanical industry: Piping for sandblasting and shot blasting equipment.

Wear-resistant alumina ceramic-lined steel pipes, with their ingenious composite structure, are the preferred solution for ensuring production continuity and reducing overall costs under demanding conveying conditions in industries such as power generation, mining, and metallurgy. When selecting the most suitable pipe type, consider the specific material characteristics (particle size, hardness, flow rate), operating temperature, and budget.

Hunan Guoci Ceramics, with its strong material research and development capabilities and advanced production processes, can customize wear-resistant ceramic-lined pipes in various sizes to meet customer application requirements. These are achieved by bonding pre-sintered alumina ceramic sheets (typically square or trapezoidal) to the inner wall of a steel pipe using a high-strength, heat-resistant adhesive, or by mechanically attaching the alumina ceramic tube to the inner wall of the outer steel pipe.
