Welcome to INEX Incorporated


INEX specializes in the manufacturing of Composite Radiant Tubes (CRTs). INEX CRTs consist of silicon carbide in a silicon matrix and are made by our exclusive patented, simple fabrication process using low-cost abundant raw materials.

Composite radiant tubes were put on the market in 1988 to take the place of conventional metal alloy and mullite radiant tubes used in heat treating furnaces around the world.
To Improve Your Operation and Save Money, The Choice Becomes Obvious...
Metal alloy radiant tubes can result in poor life due to:
- Creep
- Melt Through
- Oxidation
- Carburization
The end results are high maintenance costs and increased downtime.

In addition to poor life, the heat flux of conventional radiant tubes is also limited by low maximum temperature.

The INEX Silicon/Silicon Carbide composite tube on the left side of the adjacent image was tested for 360 hrs. The alloy 600 tube on the right was tested for less than one hour.

For Higher Temperature Capability...
- 2450°F Maximum Tube Temperature
- Heat Flux: 200 BTU/hr/in^2
For Low Cost...
- A unique dual phase, composite material- silicon/silicon carbide, has been specifically formulated for high performance and low cost.
- Our innovative, patented manufacturing process produces composite radiant tubes at a price competitive with conventional metal tubes.
- Using INEX CRTs lowers operating expenses:
- reduces furnace downtime
- reduces tube replacements
- reduces labor time
- reduces cycle time
- handle higher temperature work
Where Other Tube Materials Fail, INEX Composite Radiant Tubes Are The Obvious Choice.
