Our high-purity alumina cylinders are available in a vast array of technical configurations. We offer both "straight-wall" and "interlocking" designs to prevent the cylinders from shifting under high pressure. The sintering process is conducted in computer-controlled kilns at 1700°C to ensure complete phase transformation. We can provide cylinders with a polished internal surface (Ra < 0.4μm) for applications where material sticking is a concern. The cylinders can be supplied as standalone components or pre-installed into steel pipes using specialized high-temperature resins or cement. Every cylinder is inspected for dimensional accuracy and structural integrity using non-destructive testing methods. We also provide full traceability for our raw materials, ensuring that our "99% Alumina" claim is backed by rigorous laboratory analysis.
Industrial Applications
High-purity alumina cylinders are extensively used in Pneumatic Conveying Systems for materials like fly ash, cement, and pulverized coal. Their seamless design is particularly effective in Hydrocyclones and Slurry Pumps within the mining industry, where they protect the internal housings from high-velocity particle impact. In the Food and Pharmaceutical industries, our 99% purity cylinders are used because they are chemically inert and will not contaminate the product. Lithium Battery Production also relies on these cylinders to transport cathode and anode materials without metallic pickup. In Oil and Gas, they serve as liners for choke valves and flow lines handling sand-laden crude. Additionally, these cylinders are used as Grinding Media Housings in ball mills and as protective sleeves for high-temperature sensors in industrial furnaces. Their ability to resist wear, heat, and chemical attack makes them a universal solution for precision engineering challenges.
Manufacturing Advantages
- Monolithic Seamless Design: Eliminates joints and "step-wear," which are the primary failure points in tiled pipes.
- Ultra-High Hardness: The 99% alumina grade provides exceptional resistance to fine-particle erosion and sliding wear.
- High Purity: Ensures no contamination of the conveyed medium, critical for chemical and battery industries.
- Precision Dimensional Control: Diamond grinding allows for exact fitments in tight-tolerance mechanical assemblies.
- Zero Porosity: Prevents liquid absorption and internal corrosion of the outer steel shell.
- Enhanced Flow Rates: The smooth internal bore reduces friction, leading to significant energy savings over the life of the system.
