Sialon thermocouple protection tubes are mainly used in high temperature metal liquid for protecting thermocouple. Max temperature can up to 1450 deg C. The sialon protection tubes are best choice for indirect temperature sensing in molten metal. The low pressure die casting machine, high temperature melting furnace, especially aluminum wheel manufacturer very like this thermocouple protection tube.

Advantage of sialon protection tubes

Excellent Thermal Shock and Corrosion Resistance

Non-Wetting in Molten Metals Such as Aluminum and Zinc

Thin Tube Walls For Fast Temperature Response

Tubes Will Not Contaminate The Melt (Chemically Inert)

Higher Strength and Density Than Conventional Ceramics

Gas Tight Thermocouple Tube

Long Service Life

Maximum Service Temperature of 1450°C

The sialon thermocouple tubes are better than silicon nitride thermocouple protection tube on working life. It can save more time and labor cost during Regular maintenance.

Sialon thermocouple protection tubes are used with thermocouples to continuously monitor the temperature in molten non-ferrous metals such as Zinc, Aluminum, Copper, and Gold. These tubes are most commonly used in the Aluminum casting industry. Sialon thermocouple tubes have excellent thermal shock resistance and therefore can be directly immersed into molten Aluminum. This material is also chemically inert and non-wetting in Aluminum which helps to prevent dross buildup at the melt line. The high performance qualities of these tubes make them the perfect choice for temperature monitoring and control in Aluminum melting and holding furnaces.

The diameter of sialon thermocouple protection tubes are 16/8, 22/12, 28/16 (OD/ID) mm. The max length we can do 1500 mm.
