Protection Tubes - Sialon

 

Silicon nitride + Alumina | With Groove | With Fitting

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. Sialon protection 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. Sialon tubes are also chemically inert and non-wetting in Aluminum which helps to prevent dross buildup at the melt line. The high performance qualities of Sialon tubes make them the perfect choice for temperature monitoring and control in Aluminum melting and holding furnaces.

Sialon Thermocouple Protection Tubes can be ordered as a plain tube with or without a groove on the open end. Sialon tubes can also be ordered with a 1" NPT Steel Female Coupling for mounting to straight or angle industrial thermocouple assemblies.

  • Excellent Thermal Shock and Corrosion Resistance
  • Non-Wetting in Molten Metals Such as Aluminum and Zinc
  • Thin Tube Walls For Fast Temperature Response
  • Sialon Protection 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 1832°F or 1000°C
