7. Corrosion Resistance

Furnace Kiln High Temperature Resistant Alumina Ceramic Tube   

Features: 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.

Instructions: When in use, the temperature-measuring component of the insulation protection is installed in the protection tube, and then the open end and the even-head are sealed with high-temperature glue. When measuring the temperature, the closed end is inserted into the temperature measurement zone, and the quenching and heat is avoided during use. In order to avoid excessive damage to the protective tube.
