Since each materials has its own characteristics. It is requested to be easy installed, aseismatic with large temperature testing range and high mechanical strength considering of both tested items such as the item’s temperature, flow velocity, corrosivity, etc. and tubes including diameter, thickness, length, mechanical stress, thermal shock capacity, price, etc. The materials of thermocouple protection tube could be chose according to the situations and needs.

There is a strong capacity of silicon carbide thermocouple protection tube(SIC tube, SiSiC tube) in the fields of heat resistance, Oxidation resistance, thermal shock resistance, wear resistance, corrosion resistance with chemical stability, etc. It is an ideal material of thermocouple protection tube with high performance as below.

• No obvious change of the strength under a high temperature of 3000 F degree.
• Excellent thermal shock resistance.
• Corrosion resistance with chemical stability.
• High thermal conductivity, 5 times higher than stainless material.
• High wear resistance which is 1.5 times higher than tungsten carbide material.
