A312 TP347 Stainless Steel Helical Serrated HFW Fin Tube
The A312 TP347 Stainless Steel Helical Serrated HFW (High-Frequency Welded) Fin Tube is a high-performance heat transfer solution designed for industrial applications requiring superior corrosion resistance, high-temperature strength, and efficient heat transfer.
Key Features
Material:
Made from TP347 stainless steel, a stabilized austenitic stainless steel containing niobium for
enhanced resistance to intergranular corrosion and excellent
high-temperature oxidation resistance.
Helical Serrated Design:
The helical serrated fins are precision-engineered to maximize surface area, resulting in
improved heat transfer efficiency. The serrated design also
enhances airflow and reduces fouling, ensuring long-term
performance.
HFW (High-Frequency Welded) Technology:
The fins are high-frequency welded to the base tube, providing a strong mechanical bond and excellent
thermal conductivity. This ensures durability and resistance to
thermal cycling.
Corrosion and High-Temperature Resistance:
TP347 stainless steel offers outstanding resistance to oxidation,
sulfidation, and other forms of corrosion in high-temperature
environments, making it suitable for demanding applications.
