Porous Ceramic Tubes for Thermocouple Insulating Protection

Product Feature
1. High quality: Max working temperature 1700C, high abrasive resistance.
2. Various sizes for your choose, diameter from 1-120mm, length from 100-1600mm
3. Various processing methods make right tubes for different usage, including extruding, casting, pressing etc.
4. Tubes can be grinding, drilling holes etc according to the requirements of customers.
Alumina ceramic thermocouple protection tubes are mainly used for the conditions that high temperature resistance is required. They are always used as protective tubes. Their operating temperature can be up to 1700° C.
Alumina thermocouple protection tubes also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts.
Additionally, ceramic thermocouple protection tubes have high hardness, wear resistance, insulation property, can be used as fuse insulating tube on the electric and electronic appliances.
Properties of Alumina Ceramics
Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1000° C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity. Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution.
Application:
Mainly used for the protection of the temperature sensor, make the temperature sensor and outside isolation, decrease or prevent components in use process by foreign materials, eroded oxidation and touch the worse.
