Alloy Steel Seamless Tube, ASTM A335 P22, HFW Fin Tube, with 11-13CR Fin Strip, For Furnace Tube
This High Frequency Welded (HFW) fin tube is constructed with a seamless alloy steel base tube (ASTM A335 P22) and 11–13% chromium fin strips, designed for high-temperature heat exchange in furnace convection coils, superheaters, and heaters. The Cr-based fins offer enhanced oxidation resistance, making the product ideal for harsh combustion gas environments.

High Heat Resistance
Base material (P22) and Cr fins maintain structural integrity under sustained high temperatures.
Corrosion & Oxidation Resistance
11–13Cr fin strips protect against flue gas corrosion, sulfur compounds, and high-temp oxidation.
Durable Weld Bonding
HFW process ensures strong mechanical connection between tube and fins, with low thermal resistance.
Long Service Life
Ideal for severe service in petrochemical and power generation industries.
Used primarily in the convection section of furnaces and heaters, especially in oil refineries, chemical plants, and power boilers.
Application Zones:
Convection Coil Tubes
Positioned after radiant tubes to absorb lower-temperature flue gas energy.
Steam Superheaters
Heat Recovery Systems (HRSG, WHRU)
