Alumina ceramic tubes are widely used in various industrial furnace for supporting, threading and insulation etc.They are recommended for use in mass spectrometers and other vacuum systems as feed through lines, thermocouple insulators, and in other applications requiring electrical and thermal insulators.

With  good thermostability , insulation , temperature resistance etc. properties , Alumina insulation tubes are

used in B-type , S-type and new type tungsten-rhenium thermocouple sleeves .
