Alumina Thermocouple Protection Tube:
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
Thermocouple protection tubes are available as a closed-end tube with a reusable stainless steel coupling device. This evice allows for two methods of use: The thermocouple protection tube can be hung by the flange or attached via the threaded end of the coupling device.
Features:
1. Materials: 95% alumina oxide, 99% alumina oxide
2. Color: white, pink, light yellow
3. Shape: one end closed
4. Application: Used for all kinds of electric heating equipment and electric equipment, and textile machinery
Advantage:
1. Good smooth and high strength
2. A variety of specifications available
3. OEM, ODM and OBM are welcomed
