Product Description


Benefits of Alumina Ceramic Tubes :

1. Electrical Insulating

2. Thermal shock resistance

3. Wear Resistance

4. High Temperature Resistance

5. High compressive strength

6. Stable Chemical Performance

7. Corrosion Resistance


Alumina ceramic is very stable in air, water vapor, hydrogen, argon, carbon monoxide and vacuum at temperatures below 1700 °C; due to the different purity of alumina when processed into a protective tube, the upper temperature limit can be different. Alumina protection tube has high air tightness, high temperature resistance, high temperature insulation and corrosion resistance.
