Higher Operating Temperatures - Most alloy tubes give off an average of or maximum of 55 BTU/hr/in2 where INEX tubes allow tube temperatures up to 2450°F (1340°C) with heat flux of 200 BTU/hr/in2. Because our tubes can be fired hotter, they provide shorter furnace recovery and reduced cycle times. With this in mind, consider a smaller INEX composite tube to do the job of a larger metal tube for increased performance and savings.Longer Tube Life - Traditional metal tubes frequently fail due to creep, oxidation, melt through and carburization. As you can see from the example to the left, an INEX composite radiant tube will outlive all other types and literally lower your operating expenses with reductions in furnace downtime, tube replacements, and labor. Increased Heat Flux - Increased heat flux in radiant tubes allows faster recovery. INEX composite radiant tubes allow you to get up to operating temperature faster than traditional metal tubes, ensuring increased productivity.

If your back room is beginning to pile up with scrap tubes, you need to talk to the experts. INEX are innovators and leaders in the field of Composite Radiant Tubing (CRT's). A unique manufacturing method using silicon carbide in a silicon matrix is applied with our own-patented process. Our special composite based system was introduced in 1988 to provide the international heat-treating market with a more efficient heating source than traditional alloy tubing assemblies. Proven time and time again in hundreds of furnaces with thousands of tubes around the world, INEX U-Tubes are now available to suit your unique furnace dimensions. INEX CRT's maximize transfer of radiant thermal energy for applications in batch and continuous heat-treating furnaces. Our tubes are easy to install in a wide range of configurations for both furnace upgrades and rebuilds.
