ASME SA179 L Type Finned Tube with Al1060 Fins For Industrial Boilers & Economizers

ASME SA179 L Type Finned Tube with Al1060 Fins | Industrial Boilers & Economizers

Product Overview

Our ASME SA179 L Type Finned Tube with Al1060 Fins is engineered for high-efficiency heat transfer in industrial boilers and economizers. Combining a precision cold-drawn carbon steel base tube (ASME SA179) with high-purity aluminum fins (Al1060), this finned tube delivers superior thermal performance, robust mechanical bonding, and long-term reliability under fluctuating temperatures and pressures. The L-type embedded fin design eliminates contact thermal resistance, ensuring optimal heat recovery and energy savings for industrial boiler systems.

Key Components & Materials

1. Base Tube: ASTM A179 (Seamless Cold-Drawn Low-Carbon Steel)

Chemical Composition (Heat Analysis)

Source references: ASTM A179 / ASME SA179 standard requirements

Note: The material does not have specified requirements for Chromium (Cr), Molybdenum (Mo), Nickel (Ni), Copper (Cu), or Vanadium (V) under this standard .

Mechanical Properties

Source references: ASTM A179 / ASME SA179 standard requirements

2. Fins: AL1060 (Commercial Purity Aluminum)
Superior thermal conductivity (~234 W/m·K), lightweight, naturally corrosion-resistant, and cost-effective.
99.6% pure aluminum with high thermal conductivity (222 W/m·K); lightweight, ductile, and vibration-resistant; forms a durable metallurgical bond with the base tube.

3. Fins Type: L type

The fin root is shaped as an "L" and tightly wrapped around a pre-grooved tube surface, ensuring stable mechanical contact and efficient heat transfer.

Why Choose ASME SA179 L Type with AL1060 Fins?

• Enhanced Heat Transfer Efficiency
  • The high thermal conductivity of AL1060 aluminum fins significantly increases the overall heat transfer coefficient, allowing for smaller heat exchanger footprints and lower energy consumption.
• Reliable Mechanical Bonding
  • The L-type mechanical winding process creates a strong, durable bond between the fin and the tube. This design withstands thermal cycling and vibration better than some adhesive-based alternatives.
• Corrosion Resistance in Normal Atmospheres
  • AL1060 naturally forms a protective oxide layer, offering good resistance to atmospheric corrosion. The carbon steel base tube maintains robust mechanical strength under pressure.
• Economic and Flexible Manufacturing
  • This finned tube type provides an excellent balance between performance and cost. Fin thickness, height, and pitch can be customized to meet specific thermal and aerodynamic requirements.

Typical Applications

• Air-cooled heat exchangers (ACHEs)
• Radiator coils for generator and compressor cooling
• Dry coolers and condensing units
