High-purity Alumina ceramic lining: Typically, 92%, 95%, or 99% pure Alumina ceramics are used, such as Jingcheng Special Ceramics' K95 alumina ceramic. It boasts a hardness of HRA85 or higher, a density ≥3.8g/cm³, a compressive strength ≥1200MPa, and excellent wear resistance, with a volumetric wear rate ≤0.03cm³/(kg・m).

Armored Structure Design: Armored Wear-resistant ceramics are typically constructed by firing a ceramic tube as a whole and then pouring it into a steel pipe with a specialized filler, creating a "ceramic-metal" composite structure. This structure leverages the high strength, toughness, and impact resistance of the steel pipe with the high hardness, wear resistance, corrosion resistance, and heat resistance of the alumina ceramic, overcoming the shortcomings of the steel pipe's low hardness and poor wear resistance, and the ceramic's low toughness. 

Performance Advantages

High Wear Resistance: The Ceramic Lining has a microhardness of HV 1000-1800, making it ten times more wear-resistant than hardened medium-carbon steel and superior to tungsten-coated carbide. It effectively resists erosion and wear from materials, significantly extending the service life of the pipe.

Excellent Corrosion Resistance: Alumina ceramic is a neutral material with stable chemical properties. It is resistant to various inorganic acids, organic acids, and organic solvents. Its corrosion resistance is over ten times that of stainless steel, allowing it to operate stably in harsh chemically corrosive environments.

Excellent Heat Resistance: It can operate for long periods within a temperature range of -50°C to 900°C. Some high-purity Alumina ceramic-lined pipes can withstand even higher temperatures, such as 99% alumina ceramic, which can withstand temperatures up to 1600°C, demonstrating excellent thermal stability.

Easy Installation: Because the outer layer is a metal steel pipe, it can be installed using welding, flanges, quick-connects, and other methods, making it easy to install and reducing installation costs. Application Areas

Power Industry: Suitable for pipelines used in power plants for pulverized coal transportation, ash discharge, and desulfurization slurry transportation, effectively extending pipeline service life and reducing maintenance costs.

Mining Industry: Suitable for ore and tailings transportation, resisting abrasion from high-hardness ore particles and reducing pipeline replacement frequency.

Metallurgical Industry: Suitable for blast furnace coal injection and slag conveying in ironmaking, as well as for ferroalloy transportation and refining in steelmaking, meeting high-temperature, wear-resistant, and corrosion-resistant requirements.

Chemical Industry: Suitable for conveying media such as acidic and alkaline solutions, corrosive gases, and slurries, such as various corrosive material conveying pipelines in chemical plants, improving pipeline reliability and stability.
