Conical Alumina Ceramics pipes Alumina Pipe Liner Industrial Grade Alumina Ceramics Tubes
Product Description
Conical alumina ceramic pipes are a type of special ceramic pipe product made from high-purity alumina (Al₂O₃) as the core raw material, formed and sintered at high temperatures. Their core feature is the conical gradient structure of the inner and outer diameters, which combines the excellent physical and chemical properties of alumina ceramics with the fluid-guiding advantages of the conical structure. They are high-end conveying components that replace metal and ordinary plastic pipes in industrial applications. Compared to traditional pipes, the key differences lie in the material's resistance to extreme environments and the fluid-optimized design of the structure, allowing for precise matching of media conveying needs at different pressures and flow rates.

Key Features
Advantages of the conical structure: Reduces fluid resistance, minimizes pressure loss, and ensures uniform heat transfer, making it particularly suitable for applications such as catalyst carriers and hot processing.
Extreme Temperature Stability: Maintains mechanical strength even in high-temperature environments, resisting deformation or cracking with long-term use.
Excellent Wear Resistance: With wear resistance over five times that of stainless steel, it extends equipment life and reduces maintenance costs.
Excellent Electrical Insulation: Excellent dielectric properties (volume resistivity ≥ 10¹⁴ Ω・cm at 25°C) make it suitable for high-voltage industrial
applications.
