Can Sapphire Thermocouple Protection Tubes Replace Alumina and Ceramic Sheaths in High-Temperature, High-Pressure Environments?

2024-05-30

Latest company news about Can Sapphire Thermocouple Protection Tubes Replace Alumina and Ceramic Sheaths in High-Temperature, High-Pressure Environments?

Sapphire thermocouple protection tubes and sapphire thermocouple sheaths can withstand high temperatures up to 2000 degrees Celsius and pressures up to 3000 bar, making them highly suitable for harsh environments such as chemical processing, petrochemical refining, and the glass industry.

Compared to alumina thermocouple protection tubes and ceramic thermocouple protection tubes, sapphire thermocouple protection tubes and sheaths offer better material stability. They are suitable for use in high-temperature fields such as heavy oil combustion reactors and metallurgy, making them ideal replacements for alumina thermocouple protection tubes.

Sapphire thermocouple protection tubes have replaced ceramic tubes that cannot withstand metal diffusion, such as in the production of lead glass, where Pt thermocouple sheaths would melt into the glass, necessitating reproduction.

Currently, sapphire thermocouple protection tubes and sheaths have been successfully used in the following areas:

  • Semiconductor manufacturing: Alumina sapphire sheaths with up to 99.995% purity ensure a contamination-free production process.
  • Corrosive environment manufacturing: Concentrated or boiling mineral acids, high-temperature reactive oxides.
  • Glass and ceramic industry: Replacing Pt probes to ensure contamination-free processes.
  • Instrument manufacturing: Microwave digesters, high-temperature reaction furnaces, laboratory testing instruments, etc.
  • Optical applications: UV lamps, automotive lights.
  • Heavy oil reactors: Used in petrochemical and other areas.
  • Energy sector: For the removal of NOx and other pollutants.

Sapphire thermocouples, consisting of an externally sealed alumina protective sheath and an internal thermocouple capillary, also referred to as sapphire thermocouples. Due to the optical transparency and non-porosity of the single-crystal material of the sapphire sheaths, these thermocouples exhibit excellent high-temperature resistance and the ability to shield environmental temperature effects on the thermocouple.

Sapphire sheaths can withstand temperatures up to 2000 degrees Celsius and pressures of 3000 bar, making them extremely suitable for harsh environments such as chemical processing, chemical, oil refining, and glass industries. Sapphire sheaths offer superior material stability compared to alumina ceramic tubes and are used in many high-temperature fields such as heavy oil combustion reactors and metallurgy.

Sapphire sheaths have already replaced ceramic tubes that cannot resist metal diffusion, such as in lead glass production, where Pt thermocouple sheaths would melt into the glass, leading to the need for reproduction.
