Embedded Finned Tubes – A179 Base Tube Material
Embedded finned tubes, also known as G-type finned tubes, are high-performance heat transfer components widely used in industrial heat exchangers. The product uses ASTM A179 seamless cold-drawn low-carbon steel as the base tube combined with aluminum fins that are mechanically embedded into the tube wall. This design significantly increases the external surface area, delivering superior heat transfer efficiency in air-cooled and gas-liquid applications.
Embedded Finned Tube Structure – A179 Base Tube Material
The tube consists of three main elements:
Chemical Composition – A179 Base Tube Material
| Element | A179 Base Tube (wt%) | Aluminum Fin (1100 Grade, wt%) |
|---|---|---|
| Carbon (C) | 0.06–0.18 | ≤ 0.20 (impurity) |
| Manganese (Mn) | 0.27–0.63 | ≤ 0.05 |
| Phosphorus (P) | ≤ 0.035 | ≤ 0.05 |
| Sulfur (S) | ≤ 0.035 | ≤ 0.05 |
| Silicon (Si) | – | ≤ 0.95 |
| Aluminum (Al) | – | ≥ 99.00 |
| Iron (Fe) | – | ≤ 0.95 |
Dimensional Tolerance Range – A179 Base Tube Material
| Parameter | Standard Range | Tolerance |
|---|---|---|
| Base Tube OD | 15.88–50.8 mm | ±0.10 mm |
| Base Tube Wall Thickness | 1.65–4.00 mm | ±10% |
| Fin Height | 6.35–15.88 mm | ±0.20 mm |
| Fin Thickness | 0.30–0.50 mm | ±0.03 mm |
| Fin Pitch (FPI) | 5–11 fins per inch | ±0.5 FPI |
| Embedded Depth | 0.15–0.25 mm | ±0.03 mm |
| Total Tube Length | Up to 12,000 mm | ±2 mm |
