Alumina industrial Wear-resistant ceramic pipes and accessories are key components used in industrial material transportation, offering excellent wear and corrosion resistance.

Alumina Industrial Wear-resistant ceramic pipes

Performance Characteristics

High Wear Resistance: Alumina ceramic has a Rockwell hardness of HRA80-90, second only to diamond. Its wear resistance is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron, effectively resisting material erosion and extending pipe service life.

High Corrosion Resistance: The ceramic layer is a neutral material, resistant to acid, alkali, and seawater corrosion, maintaining stable performance in harsh chemical environments.

Low Operating Resistance: The smooth inner surface has a roughness superior to that of metal pipes, with a resistance coefficient of only 0.0193, reducing energy consumption during material transportation.

Excellent Thermal Stability: The low thermal expansion coefficient allows for long-term stable operation within a temperature range of -50°C to 700°C. Some Ceramic pipes with specialized processing techniques can withstand temperatures of up to 850-900°C. · Lightweight: 50% lighter than cast stone pipe, making it easier to transport and install while also reducing the overall load on the equipment.

· Manufacturing Process

· Centrifugal Casting Composite Process: Utilizes self-propagating high-temperature synthesis combined with high-speed centrifugal technology to form a uniform and dense ceramic layer and transition layer. Suitable for complex structures such as straight pipes, elbows, and tees.

· Chip Ceramic Process: Alumina ceramic sheets are bonded to the inner wall of the pipe using adhesive. This is a low-cost process, but its temperature resistance is limited to ≤150°C, making it suitable for low-pressure environments.

· Spot Welding and Clip-on Process: Ceramic sheets are pre-drilled and then welded to the inner wall of the steel pipe. A ceramic cap protects the weld points, resulting in greater reliability but higher cost.

· Specifications: Nominal diameters (DN) generally range from DN15 to DN2000, with common bend radii of 1.5D to 10D. Pressure ratings include PN10, PN16, and PN25. The product can be selected based on different operating pressure requirements. Wear-Resistant Ceramic Pipe Fittings for the Alumina Industry

Ceramic elbows: These are key components for changing the direction of pipes in piping systems. They come in various types, including patch, welded, and sleeve styles. The patch style uses a special ceramic glue to adhere the Ceramic Lining to the pipe's inner wall. The welded style uses a combination of adhesive bonding and spot welding to securely weld the ceramic lining to the inner wall of the steel pipe. The sleeve style uses a ceramic tube inserted into the steel pipe to connect the lining.

Ceramic tees: Used at pipe branches. Their structure and wear-resistant principles are similar to those of ceramic elbows. Different connection methods and ceramic lining structures can be selected based on actual operating conditions to ensure optimal wear resistance during material diversion and confluence.

Ceramic reducers: Primarily used to connect pipes of different diameters, ensuring a smooth transition between pipe inner diameters and reducing resistance and wear at the diameter change point. The wear-resistant ceramic lining is made of the same material and process as other ceramic pipe fittings, effectively resisting material erosion. ·Ceramic flange: used for connecting pipes, with wear-resistant and corrosion-resistant properties, it can ensure the sealing and wear resistance of the pipe connection parts, prevent material leakage and wear of the connection parts.
