What is reaction bonded silicon carbide SiSiC thermocouple protection tube?

Reaction bonded silicon carbide SiSiC thermocouple protection tube has the characteristics of anti-oxidation, thermal shock resistance, excellent thermal conductivity, corrosion resistance, wear resistance. It is an ideal protection tube for thermocouple used in metallurgy, ceramic, large boiler and chemical industry.

The silicon carbide has excellent thermal conductivity and small thermal expansion, the physical properties keeps very good stability at high temperature.

 SiSiC/RBSiC Thermocouple Protection Tubes are widely used for high temperature measurement and controlling in metallurgy, chemical & ceramics industries etc.

The advantages of reaction bonded silicon carbide SiSiC thermocouple protection tube

① Ultra-high hardness and superior wear resistance.

Thanks to the excellent hardness and abrasive resistance, Silicon Carbide tilecan effectively protect the part where need wear protection and prolong the service life of the equipment.

② Good wear resistance in sliding and abrasive environments

③ Corrosion resistance. Silicon carbide can tolerates a wide range of acids and alkalis.

④ High temperature resistance.

⑤ Good dimensional control of complex shapes.

⑥ High oxidation resistance.

⑦Low thermal expansion and high thermal conductivity leading to excellent thermal shock resistance.
