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 ($237\text{W/mcdotpK}$) and corrosion resistance.

​​2. Material & Chemical Composition​​

• ​​Base Tube​​: Carbon steel (ASME SA179, equivalent to ​​C1020​​).
• ​​Fin Material​​: AL1060 aluminum (99.6% purity).
• ​​Key Properties​​:

​​3. Mechanical & Thermal Performance​​

​​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.
