NSiC Thermocouple Protection Tubes



NSiC Thermocouple Protection Tubes With One End Closed


NSiC Protection Tubes has excellent oxidation resistance and has higher strength than RSiC protection tubes. 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. NSiC protection tube is the best material for measuring the temperature of molten aluminium industry. 



NSiC Thermocouple Protection Tubes characteristics:

@Excellent oxidation resistance

@Higher strength

@1500℃ Higher temperature resistance

@Very good thermal shock resistance

@Good corrosion and erosion resistance
