Severe Thermal Shock Testing

This test demonstrates the superior thermal shock resistance of INEX Silicon - Silicon Carbide (Si-SiC) composite tubes. 

  • Conventional ceramic (Mullite) tubes failed after just one cycle of this test.

  • However, INEX Si-SiC radiant tubes survived all five (5) test cycles with no observable damage.





Test System: INBZ-1001 
Input: 15,000 BTU/hr, Natural Gas @ 20% Air 
Materials: INEX Si-SiC & Mullite radiant tubes

Test Duration: 5 Cycles 
Average Heating: 160°F per minute
Average Cooling: 256°F per minute 

Conducted by Pyronics Inc., Cleveland, Ohio.
