about Schunk-Inex equipment
| Welcome
to Schunk-INEX Corporation
Schunk-INEX specializes in the manufacturing of Composite
Radiant Tubes (CRTs). Schunk-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... |
|
|
|
|
| For
Longer Tube Life... |
|
|
|
|
|
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 Schunk-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 Schunk-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, Schunk-INEX Composite
Radiant Tubes Are The Obvious Choice. |
