Wear Resistant Silicon Nitride Ceramic Thermocouple Protection Tube for Sale
Silicon nitride ceramic thermocouple protection tube protects the sensitive thermocouple element from aggressive compounds in the furnace atmosphere. Due to their very good thermal conductivity, the accuracy of the thermocouple reading is increased.The silicon nitride ceramic has very high working temperature, up to 1200℃.It has good chemical resistance and good thermal conductivity for accurate metering.
1. Long service life
2. Sintering: GPSN/RSSN (gas pressure sintering, reaction sintering)
3. Good abrasive resistance
4. Excellent thermal shock resistance
5. Top refractory
6. Reduced maintenance requirements and ease of maintenance
7. Anti-corrosion in the high-temperature
8. Perfect electrical insulation resistance
9. Customization available
Silicon nitride ceramics characteristics and its low weight make silicon nitride an excellent material choice for demanding applications. This is why components made of silicon nitride ceramics are successfully used in various welding processes.
