KL Type Wound Finned Tube (Base Tube A179 + Fin AL) for High-Efficiency Heat Transfer


1. Product Introduction: A179 Carbon Steel Base Tube with Aluminum Fins


The KL series wound finned tubes integrate a high-strength A179 carbon steel base tube with corrosion-resistant aluminum fins using advanced mechanical winding technology. Designed for extreme thermal cycling environments (operating range: -40°C to 250°C), these tubes amplify heat transfer efficiency by 4–8x compared to bare tubes. Ideal for gas-to-liquid heat exchange, the aluminum fins maximize surface area while the A179 base ensures structural integrity under 30 MPa pressure.


2. Finned Tube Structure & Manufacturing Process


  • Base Tube: Seamless cold-drawn A179 carbon steel, providing leak-proof performance.


  • Fins: Pure aluminum (AL 1100/AL 3003) strips wound helically for optimal turbulence.


  • Embedding Process: 
    • Fins are tension-wound at 200–300 RPM into precision-cut base tube grooves.
    • Cold-work bonding creates a metallurgical interlock (shear strength >35 MPa) without welding.
    • Post-winding annealing eliminates residual stress.


3. Chemical Composition of Base Tube (A179) & Fin (AL)


Table: Material Composition Compliance (ASTM Standards)


Component A179 Carbon Steel (%) AL 1100 Aluminum (%)
C 0.06–0.18 ≤ 0.20 (Fe + Si)
Mn 0.27–0.63 ≤ 0.05 (Cu)
P ≤ 0.035 99.0+ Al (min)
S ≤ 0.035
Si ≤ 0.10 ≤ 0.95 (Si)
Al Balance


4. Dimensional Tolerances & Specifications


Table: Precision Engineering Standards (Customizable Sizes)


Parameter Tolerance Range Standard Size
Base Tube OD ±0.1 mm 15.88–50.8 mm
Base Tube Thickness ±10% 1.24–3.68 mm
Fin Height ±0.15 mm 12.7–19.05 mm
Fin Thickness ±0.02 mm 0.3–0.5 mm
Fin Density ±1 fin/inch 7–11 FPI (fins per inch)
Straightness ≤1.5 mm/m length


5. Key Performance Advantages


  • Thermal Efficiency: Fin-to-base contact ratio >96%, reducing thermal resistance.


  • Corrosion Resistance: Aluminum fins self-passivate in humid/acidic environments (pH 4–9).


  • Mechanical Durability: Withstands 50,000+ thermal cycles without fin loosening.


  • Easy Maintenance: Smooth fin surface minimizes fouling; cleanable with air/water jets.


  • Weight Reduction: 40% lighter than all-steel alternatives.


6. Application Fields


  • Energy Recovery: Boiler economizers (reducing flue gas to 90°C), CHP systems.


  • Process Industries: Sulfuric acid plants, refinery gas coolers, drying ovens.


  • HVAC & Refrigeration: Evaporators/condensers for chillers (-30°C to 150°C).


  • Renewable Energy: Biomass boilers, geothermal heat exchangers.


7. Our Manufacturing Expertise & Quality Assurance


With 15+ years in finned tube production, we guarantee:


  • ISO 9001-Certified Production: Laser-measured dimensional checks every 50 tubes.

  • Custom Solutions: Tailor fin density/materials (e.g., AL 3003 for saltwater applications).

  • Testing Protocols: Hydrostatic pressure tests (2x design pressure), fin bond shear tests.

      Global Supply: 5,000+ tons/year capacity; lead time ≤4 weeks for bulk orders.
