Product Description

High temperature insulation Al2o3 alumina ceramic porcelain tube

The Alumina ceramic tube are constructed of pure 99.7% Al2O3 that has superior gas and vacuum tightness and excellent insulating properties even at elevated temperatures. The alumina ceramic tube/rod/bar is an ideal wear-resistance material for delivering the sand, mine, ash dregs and molten aluminium, has excellent conductivity, high machinery strength and high temperature resistance, can resist to the acid, high temperature, corrosion and static electricity. Al2O3 is the most important technical ceramic material. It is characterized by high hardness, high compressive strength and corrosion resistance even at high temperatures. Through the content of Al2O3 in the material,these properties can be tailored to the application of customer. Other material like Mullite , Zirconia, Silicon Carbide, Silicon Nitride bonded Silicon Carbide is also available.

Features of alumina porcelain Tube

1. High quality: Max working temperature 1800C, high abrasive resistance.

2. Various sizes for your choose, diameter from 1-120mm, length from 10-2000mm

3. Various processing methods make right tubes for different usage, including extruding, casting, pressing etc.

4. Tubes can be grinding, drilling holes etc according to the requirements of customers.

5.Stiffness texture.

6. Large quantity in stock can provide fast delivery and very competitive prices.
