ASTM A179 L Type Finned Tube With AL1060 Fins For Heat Exchangers Boilers

ASTM A179 L-Type Finned Tube with AL1060 Fins For Heat Exchangers and Boilers

An L-Type finned tube is a type of heat exchanger component used to enhance heat transfer between fluids (liquids or gases) in industrial applications, such as power plants, petrochemical facilities, HVAC systems, refrigeration, and more. The key feature of an L-Type finned tube is its unique fin attachment method, which forms durable and effective fins around the outer tube surface.

The ASTM A179 L-Type finned tube with AL1060 fins is a specialized heat exchanger component designed for efficient heat transfer in various industrial applications. Here’s a breakdown of its key features and applications:

Key Features:

1. Base Tube (ASTM A179):

Chemical Composition of ASTM A179 (Weight %)

Note: ASTM A179 is a low-carbon steel with no significant alloying elements, making it highly weldable and suitable for heat exchangers.

Mechanical Properties of ASTM A179

Key Notes:

Cold-drawn seamless tubes ensure high dimensional accuracy and smooth surfaces.

Excellent ductility and formability due to low carbon content.

Suitable for moderate-pressure and high-temperature applications (e.g., boilers, condensers).

2. Fins:

• Material: AL1060 (99.6% pure aluminum).
• Fin Type: L-Type (Embedded Fin) – The aluminum fin strip is wound into a machined groove on the tube and mechanically bonded for secure attachment.
• Fin Height & Density: Customizable (e.g., 5-16 mm height, 5-11 fins per inch).

Comparison with Common Fin Tube Materials

Why This Matters for L-Type Finned Tubes?

• The A179 tube provides structural strength for pressurized systems.
• AL1060 fins maximize heat transfer while resisting corrosion.
• The L-Type (embedded) design ensures a durable bond between the two materials.

3. Key Features

✔ High Heat Transfer Efficiency – Aluminum fins (AL1060) enhance thermal conductivity.
✔ Strong Mechanical Bonding – L-Type fins resist loosening under thermal cycling.
✔ Corrosion Resistance – AL1060 provides excellent oxidation resistance in moist/outdoor environments.
✔ Lightweight & Cost-Effective – Aluminum fins reduce weight compared to stainless steel options.

Main Applications of ASTM A179 L-Type Finned Tube with AL1060 Fins :

1. Heat Exchangers & Condensers:

Used in power plants, refineries, and chemical processing for steam condensation, gas cooling, and heat recovery.

2. HVAC & Refrigeration Systems:

Enhances heat transfer in air coolers, chillers, and evaporators due to the high thermal efficiency of AL1060 fins.

3. Industrial Boilers & Economizers:

Improves heat exchange efficiency in waste heat recovery systems and boiler exhaust gas applications.

4. Oil & Gas Industry:

Used in gas coolers, compressors, and LNG heat exchangers where corrosion resistance and thermal performance are critical.

5. Marine & Offshore Applications:

Resistant to saltwater corrosion, making it suitable for shipboard condensers and desalination plants.
