ASME SA179 carbon steel seamless tube, 1060 aluminum fin-wrapped L-shaped fin tube, suitable for air coolers/heaters
The 1060 aluminum fin-wrapped L-shaped fin tube is a high-performance composite heat transfer element designed to improve air-side heat transfer performance. It utilizes ASME SA179-compliant cold-drawn seamless carbon steel pressure vessels with 1060 aluminum fins spirally wound in an interlocking L-shaped structure. This unique design combines the aluminum fins' high thermal conductivity (approximately 200 W/m·K) with mechanical strength. The L-shaped foot fixture prevents the fins from loosening due to airflow erosion and thermal cycling. It is designed specifically for air coolers, heaters, and fin-tube heat exchangers.
Operating Temperature: 230°C. Features: The winding process provides high production efficiency, uniform spacing, excellent heat transfer, a high fin ratio, and protection of the base tube from airflow erosion.

| Dimension | L-Type Fin Tube | KL-Type Fin Tube | LL-Type Fin Tube |
|---|---|---|---|
| Structure | • Aluminum fin with single L-shaped hook at root • Line contact with base tube |
• Knurled L-foot design • Grooves pressed into fin root for mechanical locking |
• Extended L-foot (Long Leg) • Double-hook structure at root |
| Vibration Resistance | ★★☆ (Better than embedded, weaker than KL/LL) |
★★★ (Excellent) |
★★★ (Dual hooks prevent loosening) |
| Thermal Contact Resistance | • Relatively high (Limited by line contact) |
• Lowest (Knurling increases contact area) |
• Low (Improved vs. L-type, but higher than KL) |
| Process Complexity | • Simple & mature (Lowest cost) |
• Higher (Requires precision knurling; cost ↑) |
• Moderate (Precision forming needed for dual hooks) |
| Max. Service Temp. | ≤ 250°C (Al fin) | ≤ 280°C (Knurling resists thermal expansion) |
≤ 260°C (Dual hooks resist thermal fatigue) |
| Typical Applications | • HAVC coils, economizers • Low-vibration environments |
• Power plant air preheaters • High-flow/high-vibration gas heat recovery |
• Air-cooled condensers (ACC) • Marine heat exchangers • Medium-vibration systems |
