HFW Serrated Fin Tube made from ASTM A312 TP347H stainless steel is engineered for use in power plant systems, especially in economizers, superheaters, and convection sections where high temperatures and corrosive environments are common. The serrated fin design enhances turbulent flow, significantly improving heat transfer efficiency.
The fins are high-frequency welded (HFW) onto the base tube, ensuring a strong metallurgical bond capable of withstanding vibration, thermal cycling, and pressure fluctuations in thermal power plants.

Enhanced Heat Transfer: Serrated fins break boundary layers and improve turbulence, increasing thermal efficiency.
High Creep Resistance: TP347H offers excellent performance in long-term high-temperature service.
Anti-Oxidation Capability: Ideal for oxidizing environments in flue gas streams.
Durable Welded Joint: HFW process ensures long service life under cyclic thermal loads.
Corrosion Resistance: Resistant to sulfidation, carburization, and intergranular corrosion.
Economizer Coils
Convection Zone which is the key heat transfer area. It is located in the rear of the boiler fllue gas path. This area handles high-temperature exhaust gases from the combustion process.
Enhanced Heat Transfer from turbulent gas flow around the serrated surfaces.
Withstand Thermal Stress thanks to TP347H's high creep strength and oxidation resistance.
Low Maintenance because of their long service life even under cycling boiler operations.
