Alloy Steel Furnace Tubes

tsi furnace tube images

Furnace tubes or alloy steel tubes are designed for high-temperature applications (i.e. furnaces and fired heaters).

Renowned for quality and durability, a furnace tube is great for:

  • oil refineries
  • chemical plants
  • fertiliser plants
  • petrochemical plants

…and more.

A furnace tube is alloyed to increase hardness, strength and chemical resistance – combining the properties of steel and other elements, such as carbon, nickel, chromium, silicon, manganese, tungsten, molybdenum and vanadium.

With a comprehensive range to choose from, and choice of sizes, grades, specifications and shapes, you’re sure to find what you’re looking for. But if you don’t,  here at Heat Ex Tube Limited , we can modify our products to ensure they match your exact needs.
