ASTM A179 Embedded Finned Tube with Al1060/ Al 1100 Fins For Air Cooler
ASTM A179 Embedded Finned Tube with Al1060/Al1100 Fins is a type of heat exchanger tube designed for enhanced heat transfer efficiency. Here's a breakdown of its key components and characteristics:
1. Base Tube (ASTM A179)
Material: Low-carbon steel (seamless cold-drawn)
Standard: ASTM A179 specifies the requirements for seamless cold-drawn low-carbon steel tubes used in heat exchangers and condensers.
Properties: Good thermal conductivity, corrosion resistance (in certain environments), and mechanical strength.
(1). Chemical Composition (Weight %)
| Element | Composition (%) |
| Carbon (C) | 0.06 – 0.18 |
| Manganese (Mn) | 0.27 – 0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Silicon (Si) | ≤ 0.10 |
Notes:
Low carbon content improves weldability and reduces brittleness.
Low sulfur & phosphorus minimize hot cracking and improve ductility.
(2). Mechanical Properties
| Property | Value (Minimum) |
| Tensile Strength | ≥ 325 MPa (47,000 psi) |
| Yield Strength | ≥ 180 MPa (26,000 psi) |
| Elongation (in 50 mm) | ≥ 35% |
| Hardness (Rockwell B) | ≤ 72 HRB (typically) |
Notes:
Cold-drawn process enhances strength and surface finish.
High elongation ensures good formability for bending and expansion.
Annealed/Stress-Relieved condition improves dimensional stability.
2. Fins (Al1060 / Al1100)
Al1060: 99.6% pure aluminum, excellent thermal conductivity (~230 W/m·K), good corrosion resistance.
Al1100: 99.0% pure aluminum, slightly less conductive than Al1060 but still highly efficient.
The fins are mechanically embedded into grooves on the outer surface of the steel tube, ensuring strong bonding and optimal heat transfer.
This method prevents air gaps between the fin and tube, improving thermal performance.
3. Key Features & Applications
High Heat Transfer Efficiency: The aluminum fins significantly increase the surface area, improving heat exchange.
Corrosion Resistance: Aluminum fins provide good resistance to oxidation and mild corrosive environments.
Strong Bonding: The embedded fin design ensures durability under thermal cycling and mechanical stress.
This type of finned tube is ideal for applications requiring efficient heat transfer in moderate-temperature environments, where aluminum's lightweight and high thermal conductivity are beneficial. The embedded fin design ensures long-term reliability and performance.
Applications of ASTM A179 Embedded Finned Tube with Al1060/Al1100 Fins
This type of finned tube is widely used in heat exchange systems where efficient thermal transfer, lightweight construction, and corrosion resistance are required. Below are the key applications:
1. Power Plants & Energy Recovery Systems
2. Petrochemical & Oil Refineries
3. HVAC & Refrigeration
4. Industrial Process Heating & Cooling
5. Marine & Offshore Applications
6. Renewable Energy Systems
Key Advantages for These Applications
✔ High Thermal Efficiency (Aluminum fins increase surface area).
✔ Lightweight & Compact (vs. solid steel or extruded fin tubes).
✔ Good Corrosion Resistance (Al1060/Al1100 resists oxidation).
✔ Mechanically Robust (Embedded fins prevent detachment under stress).
