Product Details

2016 best selling !!! Si3N4 silicon nitride protection tube sialon sheath

Product Description

STA supplies thermocouple protection tubes made of RSiC, SiSiC & NBSiC and sialon from its China based factories. We provide these products not only for China domestic customers, but also to worldwide.Silicon nitride (Si3N4) bonded silicon carbide (SiC) material is produced by adding industrial silicon paste into artificial aggregate.

In the chemical & process industries, the handling and movement of often very corrosive chemicals requires materials with excellent chemical stability. Traditionally, metals such as inconel have been used. However, in many applications inconel has a limited life. International Syalons manufacture Syalon tubes, which in many cases last significantly longer than inconel.

our products material:

1. Reaction Sintered Silicon carbide (RBSIC)

2. Recrystallized Silicon Carbide ceramic (RSIC)

3.Silicon Nitride Bonded Silicon Carbide ceramic (NBSIC)

4. Sintered Silicon Carbide (SSiC)

Features of silicon carbide tube

1. Best producing technology in China. Our tubes can be instead of Japanese tubes in Aluminium melt furnace.

2.Very smooth surface to avoid any blotted metal liquid.

3. Good thermal conductivity.

4. High tempreature strength

5. Special groove to be easy fixed.
