Product Description

Product Description

Customized high-temperature 95%/99% alumina ceramic tubes

Alumina ceramic tubes are mainly used to separate the different poles of the temperature measuring element, to avoid interference between the two poles or contact short circuit, so that the temperature measurement is accurate. We have a variety of high-purity alumina and mullite insulation tubes in stock, including single bore, double bores, four bores or porous insulation tubes. This type of tubes is particularly suitable for harsh environments, and can be used as insulation tubes, feed conductors, spacers, etc. And the customized requirements will be accepted

Regular dimension: Alumina insulated tubes, can be produced a single hole , double ,three and four-holes.

Application equipment:
Vacuum atmosphere tube resistance furnace, energy saving box furnace, high temperature annealing muffle furnace, precision tube furnace, environmental protection and energy saving new type tube furnace, vacuum atmosphere tube furnace, etc.
 

Regular dimension: Alumina insulated tubes, can be produced a single hole , double ,three and four-holes.
