Description

Could be customized based on your requirements or drawing.

Alumina ceramic is very stable in air, water vapor, hydrogen, argon, carbon monoxide and vacuum at temperatures below 1800 °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.
