Advantages of silicon carbide thermocouple protection tubes
Stable operation at ultra-high temperature of 1900℃
Traditional metal and ordinary ceramic thermocouple protection tubes are prone to softening, bending, thermal stress fracture, or high-temperature oxidation at temperatures exceeding 1400°C, leading to thermocouple damage and temperature measurement distortion.
GORGEOUS CERAMICS (GGS Ceramic) silicon carbide thermocouple protection tubes perfectly solve this problem. Our silicon carbide material overcomes temperature limitations, operating stably at temperatures above 1650°C in oxidizing atmospheres and withstanding extreme temperatures up to 1900°C under inert gas protection.
With its extremely low high-temperature creep rate and excellent thermal stability, our silicon carbide protection tubes maintain structural integrity and dimensional stability even at extreme furnace temperatures, ensuring continuous, accurate, and reliable temperature feedback from the thermocouple under extreme conditions.
Excellent thermal shock resistance, capable of withstanding frequent temperature rises and falls
In high-temperature operating conditions with cyclical temperature rises and falls, if the material performance is insufficient, severe thermal stress can easily accumulate inside the tube, leading to frequent cracking and breakage under rapid heating and cooling. This will seriously affect continuous production and increase your downtime maintenance costs.
GORGEOUS CERAMICS (GGS Ceramic) silicon carbide thermocouple protection tubes combine a thermal conductivity of up to 140 W/m·K with an extremely low coefficient of thermal expansion.
The superior material properties of silicon carbide enable instantaneous and uniform heat conduction and eliminate internal temperature gradients. Whether dealing with rapid heating and cooling at temperatures exceeding 1000 degrees Celsius or high-frequency temperature cycles, it maintains structural integrity, significantly reducing the risk of protection tube bursting and extending equipment maintenance cycles.
Antioxidant, wear-resistant, and corrosion-resistant
In harsh kiln environments with high temperatures, high dust levels, and highly corrosive gases or molten materials, protective tubes are easily subjected to severe surface oxidation and peeling, thinning of the tube wall due to dust erosion, and even perforation.
GORGEOUS CERAMICS (GGS Ceramic) silicon carbide thermocouple protective tubes possess excellent chemical inertness and extremely high surface hardness. Under high-temperature oxidizing conditions, a dense SiO₂ protective film automatically forms on its surface, effectively preventing further oxidation.
Lower surface wear translates to lower replacement frequency and less unplanned furnace downtime.
