Good high-temperature strength and creep resistance.
Improved resistance to oxidation and corrosion compared to plain carbon steels at elevated temperatures.
Good weldability.
2. Fin Material: AL1060
Properties:
Excellent Thermal Conductivity: (~230 W/m·K) - The primary reason for using aluminum fins.
Good Corrosion Resistance: Forms a protective oxide layer.
High Formability/Ductility: Easily shaped during manufacturing.
Low Density: Lightweight.
Low Strength: Softer than alloyed aluminums, but sufficient for many fin applications.
High Electrical Conductivity.
3. Fin Type: Embedded (G-Fin)
Manufacturing Process:
A groove is machined (often by knurling) into the outer surface of the steel base tube.
A strip of aluminum fin stock (AL1060) is fed into the groove.
High-pressure rollers or dies force the tube wall material over the edges of the aluminum strip, cold-working and mechanically locking the fin base securely into the groove. This creates a continuous, tight, mechanical bond along the entire length of the fin.
Key Features:
Strong Mechanical Bond: The fin is physically locked into the tube wall, offering excellent resistance to fin loosening due to thermal cycling or vibration.
No Solder/Braze: Eliminates issues like flux corrosion, braze alloy melting point limitations, or potential voids in the bond line.
Direct Metal-to-Metal Contact: Provides low interfacial thermal resistance (good heat transfer efficiency).
Fin Integrity: The AL1060 fin material itself remains unaltered (not melted), retaining its full thermal conductivity and corrosion resistance.
Fin Density: Allows for relatively high fins per inch (FPI).
Appearance: Typically has a clean, metallic look with a visible seam where the tube metal is rolled over the fin base.
Key Advantages:
High heat transfer efficiency.
Excellent fin bond strength and durability under thermal cycling.
Good high-temperature capability of the base tube.
Corrosion resistance of fins (AL1060) and base tube (SA209).
No low-melting-point braze alloys to limit operating temperature.
4. Application
Marine & Offshore Systems
Desalination Plant Heat Exchangers
Sulfuric Acid (H₂SO₄) Coolers
Sour Gas (H₂S) Reboilers
Steam Condensers in Geothermal Plants
Flue Gas Waste Heat Recovery
Ammonia (NH₃) Evaporators
Heat Recovery Ventilators (HRVs)
5.Typical Applications:
Heat Recovery Steam Generators (HRSGs): Economizer and evaporator sections.
Boiler Economizers: Recovering heat from flue gases.
Air Heaters (Ljungström type or tubular): Preheating combustion air.
Process Gas Heaters/Coolers: In refineries, petrochemical, and chemical plants.
High-Temperature Finned Tube Bundles: Where both elevated temperature resistance and efficient extended surface are required.
