Excellent High-Temperature Strength
Suitable for continuous operation under high heat and pressure.
Outstanding Oxidation & Sulfidation Resistance
Chromium-rich fin material resists scaling and chemical attack in furnace atmospheres.
High Welding Integrity
HFW ensures tight fin attachment with low thermal contact resistance.
Efficient Heat Transfer
The extended surface area improves convective heat exchange efficiency.
Long Service Life
Withstands cyclic thermal stress and harsh flue gas exposure.
Used in thermal and petrochemical industries, particularly in heat exchange equipment exposed to flue gases:
Furnace Convection Coils
Boiler Economizers
Superheaters and Reheaters
Heater Tubes in Refineries & Power Plants
Waste Heat Recovery Units (WHRU)
