ASME SA179 L-Type Spiral Finned Tubes with AL1060 Aluminum Fin – High-Efficiency Heat Transfer for Air Coolers & Heat Exchangers
1. Product Overview
ASME SA179 L-Type Spiral Finned Tubes are engineered for superior heat exchange in air coolers, condensers, and industrial heat exchangers. Manufactured under ASME SA179 standards, these tubes combine a carbon steel base tube with AL1060 aluminum fins for optimal thermal conductivity (237 W/mcdotpK) and corrosion resistance.
2. Material & Chemical Composition
Base Tube: Carbon steel (ASME SA179, equivalent to C1020).
Fin Material: AL1060 aluminum (99.6% purity).

4. Key Features & Advantages
Enhanced Heat Transfer: Spiral fin design increases surface area by 5–10x vs. bare tubes.
Corrosion Resistance: Aluminum fins resist oxidation in humid/coastal environments.
Customizable: Available in fin heights 6–25mm and pitches 3–8mm.
Certified Quality: Complies with ASME SA179, ASTM B209, and EN 10216.
5. Applications
Power Plants: Air-cooled condensers.
Oil & Gas: Process gas coolers.
HVAC: Industrial air handlers.
6. FAQ
Q: Why choose L-type fins over LL-type? A: L-type fins provide better mechanical stability for high-velocity airflow.
Q: Can you supply galvanized base tubes? A: Yes! We offer hot-dip galvanized or painted options for corrosive environments.
