Product Introduction

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.


The main features of the thermocouple protection tube:

1: XTL corrosion preventive or anticorrosion

2: Good ultimate and limiting performance

3: application in strong sulphuric acid severe environment

4: OSP oxidation resistance and antioxidant Antioxidative.

 5: All silicon carbide ceramic performance

Silicon Carbide Ceramic Extreme High Temperature Corrosion Resistant Thermocouple Protection Tube Materials For Furnace  

      The thermal couple protection tubes that is thermal couple sheath pipe. It has most materials for customer to choose. We can choose according to the temperature testing , pressure rating, silicon carbide ceramic thermal couple protection tube pipe sheath is produced by the international standard , we can customize the precision manufactured blind hole based on the customer demand. In the process of the temperature testing, thermocouple protection tube sheath is very important. So, if it is working  in the extra high temperature , materials of the sheath play the key role, like in the application of the steel industry, thermal couple sheath tube is not only bear the high temperature but also the corrosion and impact force of the liquid steel
