Extruded tubes made from Kanthal APMT and Kanthal APM iron-chromium-aluminium (FeCrAl) and nickel-chromium (NiCr) alloys for gas-heated or electrically heated furnaces.
Kanthal furnace tubes can be used at temperatures up to 1250°C (2280°F) and are available in sizes from 26 to 260 mm (1.02-10.2 in.) outside diameter. Kanthal APM and Kanthal APMT furnace tubes, as well as other Sandvik high-temperature tubes, are suitable for use as, for example:
- Radiant tubes (radiation tubes)
- Thermocouple protection tubes
- Muffle tubes
- Atmosphere sampling tubes
- Gas injection tubes
- Burner nozzles
Kanthal furnace tubes are also used as construction material in various furnace applications.
Longer service life with Kanthal FeCrAl alloys
Kanthal APM and Kanthal APMT iron-chromium-aluminium (FeCrAl) alloys offer several advantages compared to other tube materials such as alumina, silicon carbide and nickel-chromium (NiCr) alloys. User benefits include superior resistance to, for example, carburization, thermal shock, sagging and distortion.
