​Product Description

Conical alumina ceramic tubes are specialty ceramic tubes made from high-purity alumina (92%-99% Al₂O₃ content). Produced through an advanced sintering process, they achieve a dense and uniform structure. Their unique tapered design makes them widely used in industrial applications such as material handling, grading and screening, and chemical reactions. Their excellent mechanical strength, heat resistance, and chemical stability make them an ideal choice for a wide range of industries.

The optimized conical design enhances fluid flow, optimizes heat distribution, and facilitates integration into existing equipment. Custom sizes are available to meet the specific needs of different applications.

Technical parameters

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.
