Qingyun Hongsheng Machinery Parts Co., Ltd. is one of the most reliable manufacturers and suppliers of ceramic patch wear-resistant elbow in China. We warmly welcome you to wholesale high quality ceramic patch wear-resistant elbow at low price from our factory. If you have any enquiry about quotation, please feel free to email us.
The ceramic patch wear-resistant elbow is a key component specially designed for high-maintenance industrial pipeline systems. By incorporating a high-hardness ceramic lining, it significantly enhances the wear resistance lifespan of the elbow.
Ceramic thickness: 5 - 20mm (customized according to wear intensity), gap between patches ≤ 0.2mm.
Bonding strength: Tensile strength ≥ 24.2MPa, shear strength ≥ 7.08MPa, ensuring no delamination at high temperatures.
Service life: Design requirement ≥ 15 years, verified in actual conditions to reach 5 - 10 years.
Products Description
Advantages of Ceramic Patch Wear-resistant Elbow Performance
Extremely long wear-resistant lifespan
In scenarios such as coal powder transportation (at a flow rate of 15 m/s) and slurry flushing, the lifespan can be more than 5 times that of ordinary cast steel elbows (for example, 2-5 years in the power industry vs. traditional half-year perforation).
In the transportation of mine tailings, the lifespan is increased by 7-260 times compared to manganese steel elbows, and the annual maintenance cost is reduced by 60%.
Resistant to extreme environments
Temperature resistance: Working range -50℃ to 900℃. Resistant to high-temperature slag (such as aluminum liquid transportation) or low-temperature coal transportation.
Corrosion resistance: Resistant to acidic and alkaline media with pH values ranging from 2 to 12, as well as sulfur-containing wastewater and salt corrosion. Suitable for chemical desulfurization pipelines.
Core structure and working principle of wear-resistant ceramic pipes
Composite design
Ceramic layer: Made of alumina corundum ceramic (with Al₂O₃ content ≥ 92%-95%), hardness reaches HRA 85-90 (close to diamond), sintered at a temperature over 1600°C to form a dense corundum structure, with a wear resistance 10-200 times that of carbon steel.
Metal matrix: The outer layer is carbon steel (such as Q235) or stainless steel, providing structural support and impact resistance. The ceramic and metal are firmly bonded through metallurgical bonding or adhesive technology.
Lamination process: Includes bonding method (temperature ≤ 150°C), spot welding and clamping type (temperature up to 1000°C), or interlocking embedding structure to solve the problem of ceramic detachment.
Innovative reinforcement
Backpack design: For the back arc of the elbow (the most worn area), an external wear-resistant layer is added to form "ceramic inner liner + external reinforcement" dual protection, with a lifespan that is 5-10 times longer than that of ordinary elbows.
Fluid optimization: Large curvature radius (1.5D-5D) and smooth ceramic inner wall (roughness Ra ≤ 0.8 μm), reducing vortices and resistance, with energy consumption reduced by 15%-20%.
