Product Description

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:

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.
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.
Bonding layer: The ceramic layer is securely attached to the inner wall of the steel pipe through a special process.

Performance Advantages

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:

Features	Advantage Description
1. Extreme Wear Resistance	This is its core advantage. The alumina ceramic lining has a Rockwell hardness of up to HRA85-90, and its wear resistance is 266 times that of hardened steel and 171.5 times that of high-chromium cast iron. Under equivalent operating conditions, its service life is 10-20 times that of ordinary steel pipe, significantly reducing replacement frequency.
2. Smooth Inner Wall	The ceramic surface is as smooth as a mirror, with a low coefficient of friction. This effectively reduces conveying resistance, prevents material blockage and sticking, and reduces operating energy consumption for pneumatic conveying systems.
3. Corrosion Resistance	Alumina is a stable chemical substance with excellent corrosion resistance to acids, alkalis, solvents, and other chemical media, making it suitable for a wider range of applications than ordinary metal pipes.
4. High-Temperature Resistance	It can operate continuously in temperatures ranging from -50°C to 350°C, meeting the requirements of most industrial high-temperature applications.
5. Lightweight	Compared to integrally cast wear-resistant alloy pipes, ceramic-lined pipes are lighter, making them easier to transport, install, and support, reducing the load on engineering structures and installation costs.
6. High Overall Cost-Effectiveness	Although the initial purchase cost is higher than that of ordinary steel pipes, their exceptionally long service life significantly reduces downtime, maintenance workload, and replacement costs, resulting in significant overall economic benefits over their entire lifecycle.

Application Areas

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.
