Introduction
FEATURES & BENEFITS
✔High temperature resistance
✔Thermal shock resistance
✔High thermal conductivity
✔High mechanical strength
✔Acid and alkali resistance
✔Wear resistance
Silicon nitride bonded silicon carbide (NSiC) thermocouple protection tube is a key component in the field of high-temperature measurement. NSiC thermocouple protection tube exhibits excellent performance in extreme environments that require high temperature strength, wear resistance, and thermal stability.
Silicon nitride bonded silicon carbide (NSiC) protection tube is a high-performance ceramic component widely used as a
thermocouple protection tube in extreme environments. Combining the strength and toughness of silicon nitride with the high temperature resistance of silicon carbide.Silicon nitride bonded silicon carbide excellent material properties make it an ideal choice for applications that require high temperature strength, wear resistance, and thermal stability.
Selection Guide
Standard type: Ф 8 / Ф 10mm (balanced strength and response speed) Reinforced type:
Ф12mm with cooling flange (for continuous measurement of molten steel);
(2) Connection method
Quick clamp: suitable for frequent replacement scenarios (such as electric furnace steelmaking);
Threaded seal: M20x1.5+graphite gasket (high-pressure reactor).
Characteristics of NSiC Thermocouple Protection Tube
APPLICATION
4、SiN SiC protective tube should be preferred in the following scenarios：
（1）There is a risk of mechanical impact (such as in continuous casting production lines)；
（2）Strong corrosive molten salt environment (aluminum electrolysis, waste incineration)；
（3）Intermittent production that requires quick disassembly and assembly；
（4）Need for ultra-high precision temperature control (within+1 ℃).
