radiation tubes / Pipes is getting more popular with heat treatment industry, more and more end suers is using our ceramic radiant tubes instead of SS pipe, 

1) 3 times life as stainless steel;

2) lower cost then metal radiation tubes;

3) light weight and energy saving;

4) 1450C high temp resiatance.

material by NSiC/Si3N4-SiC Ceramics, it has very excellent resistance of metal corrosion,

also as thermocouple protection tube in temperature measuring system,or electrical heater protection tubes in metallurgy process,which can directly touch with the liquid-metal, high strength & longer life. Widely used on:
