Advantages

  • Excellent Thermal Conductivity: The HFW bonding ensures low contact resistance between tube and fin for efficient heat transfer.

  • High-Temperature Resistance: Suitable for operation in elevated temperature environments due to the alloy composition.

  • Oxidation & Corrosion Resistance: The 11-13Cr fin provides superior resistance to flue gas corrosion and scaling.

  • Strong Weld Bond: High-frequency welding results in durable and consistent fin attachment, ideal for vibrating environments.

  • Customizable Fin Geometry: Can be made with serrated or solid fins, and varied fin density, thickness, and height.


Applications

  • Economizers in Power Plants

  • Waste Heat Recovery Units (WHRU)

  • Superheated Steam Boilers

  • Process Heating Systems in Refineries

  • Industrial Furnaces and Ovens
