High Temperature Tubes

blg-dtl-img1.jpg

Seamless high-temperature tubes and furnace tubes suitable for use in applications with temperatures above 500ºC (932ºF).

High-temperature tubes includes a wide range of austenitic stainless steels and nickel alloys as well as iron-chromium-aluminium (FeCrAl) alloys, which can be used at temperatures up to 1250ºC (2280ºF).

high-temperature tubes Includes:

  • Boiler tubes
  • Composite tubes
  • Ethylene furnace tubes
  • Finned tubes
  • Furnace tubes
  • Lance tubes
  • Muffle tubes
  • Radiant tubes
  • Recuperator tubes
  • Reheater tubes
  • Superheater tubes
  • Thermocouple tubes

    • Stock program

    Heatcon holds stock of five different grades commonly used in a variety of high-temperature tube applications. We also stock composite tubes.
