SiSiC Thermocouple Protection Tubes With One End Closed


Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. its long-time stability and service life will be up to outside protection tube. Silicon carbide (SiSiC)is the best material for measuring the temperature of various metal liquid. It widely used in medium frequency forging, various heat treatment furnace, metallurgy, chemical industry, nonferrous metal smelting and other industries.



SiSiC Thermocouple Protection Tubes characteristics:

@Good oxidation resistance

@High thermal conductivity

@Lower coefficient thermal expansion

@1380℃ Higher temperature resistance

@Very good thermal shock resistance
