Silicon Carbide Ceramic High Density Thermocouple Protection Tube and Pipe Sheath Materials for Longer Thermocouple Life

Product Detail

Silicon Carbide  Ceramic High Density Thermocouple Protection Tube And Pipe Sheath Materials For Longer Thermocouple Life

     UDC Silicon Carbide ceramic thermocouple protection tube can tolerate the high temperature of 3000? and the strength force could not change, Bear the corrosion and acid resistant performance, No reaction of the strong acid and strong base. The thermal conductivity coefficient is five times compare with the stainless steel materials. The wear resistance is the one point five times compare with the tungsten carbide. This all nature property is determined that Silicon Carbide thermocouple protection tube can work well in any terms and conditions.

The main application of the Silicon Carbide thermocouple protection tube and pipe sheath:


Metal smelting, glass guide channel, combustion chamber, temperature testing of the instrument and meter protection.  

1:Maximum temperature is 1380? in air

2:Maximum temperature is 1350? in argon and nitrogen

3:It can be oxygen sensor in high temperature

4:It can be as the acidifier in the high temperature and the fusion with sodium ,potassium ,calcium.

5:It thermocouple protection pipe is in fairly good chemical stability.
