Radiant tubes (radiation tubes) in Kanthal APM and Kanthal APMT iron-chromium-aluminium alloys (FeCrAl alloys) available as complete ready-to-install assemblies according to almost any customer specification.
We provide, for example, welding of flange and bottom or distance spacers to the radiant tubes. The Kanthal program also includes U and W shaped radiant tubes.
Longer service life
Radiant tubes in Kanthal APMT and Kanthal APM FeCrAl alloys offer several advantages compared to ceramic tubes, silicon carbide tubes and nickel-chromium (NiCr) alloy-based tubes.
User benefits include superior resistance to, for example, carburization, thermal shock, sagging and distortion. This is due to the materials' excellent mechanical properties and their capability of forming a dense and adhesive oxide film that protects against corrosion and atmospheric attack.
The lifetime of radiant tubes in Kanthal APMT and Kanthal APM is often many times longer than that of NiCr alloy-based tubes.
