Product Description
Welding fin tubes with serrated helical fins feature a base tube made of ASTM A312 TP347 stainless steel, making them ideal for corrosive environments and high-temperature applications in chemical processing, petrochemical, and renewable energy industries.
ASTM A312 TP347 is an austenitic stainless steel stabilized with columbium, offering excellent corrosion and oxidation resistance, particularly suited for applications requiring high corrosion resistance and stability at elevated temperatures.
HFW (High Frequency Welded) Serrated Fin Tubes provide superior heat transfer properties compared to solid fins, with additional benefits including improved ash deposition prevention and larger heat exchange area.
