ASME SA213 T22 HFW Serrated Fin Tube with CS Fin
Base Tube Material: ASME SA213 T22
ASME SA213 T22 is a chromium-molybdenum low-alloy steel widely used in high-temperature and high-pressure service. With a composition of 2.25% chromium and 1% molybdenum, it offers excellent resistance to high-temperature oxidation, hydrogen attack, and creep strength. This makes it particularly suitable for power plant boilers, superheaters, reheater sections, and heat exchange equipment. The material maintains superior mechanical properties and structural stability under sustained elevated temperatures, making it an ideal choice for high-temperature pressure components.
What is an HFW Serrated Fin Tube?
An HFW Serrated Fin Tube is a high-efficiency heat transfer element manufactured using high-frequency welding technology. A serrated steel strip is helically wound and welded onto the outer surface of the base tube. The serrated fin design significantly increases the heat transfer surface area and enhances fluid turbulence, leading to markedly improved heat transfer efficiency. This type of fin tube combines a high-strength base tube with carbon steel fins, ensuring durability under high temperatures while maintaining cost-effectiveness, making it suitable for various demanding industrial applications.

Competitive Advantages
1. Excellent High-Temperature Performance:
T22 material maintains good strength and oxidation resistance at elevated temperatures, suitable for continuous high-temperature operation.
2. Enhanced Heat Transfer with Serrated Fins:
The serrated fin structure increases fluid turbulence and expands the heat transfer area, significantly improving overall thermal efficiency.
3. Robust and Reliable HFW Process:
The High-Frequency Welding technique ensures a strong bond between the fins and the base tube, providing high resistance to thermal shock and fatigue, resulting in a long service life.
4. Cost-Effective Solution:
The combination of an alloy steel base tube with carbon steel fins offers a balanced solution, delivering performance at a manageable cost for a wide range of industrial applications.
Applications of ASME SA213 T22 HFW Serrated Fin Tube
1.Superheaters and Reheaters in Power Boilers
2.Process Heaters and Heat Exchangers in Petrochemical Plants
3.Air Preheaters in Waste Heat Recovery Systems
4.Hydroprocessing and Catalytic Reforming Units in Refineries
