ASTM A179 Embedded Finned Tube / G Finned Tube with Aluminum Fins For Heat Exchanger
An embedded finned tube is a type of heat exchanger tube designed to improve heat transfer efficiency by increasing the surface area in contact with the surrounding medium (e.g., air, gas, or liquid). It consists of a base tube (typically made of metal) with fins that are mechanically embedded or bonded to the outer surface of the tube. The fins are usually made of a highly conductive material, such as aluminum or copper, to enhance heat transfer.
The chemical composition of ASTM A179 steel tubes is primarily low-carbon steel:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.06-0.18 |
| Manganese (Mn) | 0.27-0.63 |
| Phosphorus (P) | 0.035 max |
| Sulfur (S) | 0.035 max |
| Silicon (Si) | 0.10-0.35 |
The low carbon content ensures good weldability and formability, while manganese provides strength and toughness. Phosphorus and sulfur are minimized to avoid brittleness.
ASTM A179 tubes meet specific mechanical properties for heat transfer applications:
| Property | Requirement |
|---|---|
| Tensile Strength | ≥ 325 MPa (47,000 psi) |
| Yield Strength | ≥ 180 MPa (26,000 psi) |
| Elongation (in 2 in or 50 mm) | ≥ 35% (for wall thickness ≤ 0.015 in or 0.38 mm) ≥ 30% (for wall thickness > 0.015 in or 0.38 mm) |
| Hardness | Not explicitly specified, but typically low due to the low carbon content |
The ASTM A179 Embedded Finned Tube with Aluminum Fins is designed for applications where efficient heat exchange is critical. The combination of ASTM A179 steel and aluminum fins makes this product highly effective in various industrial applications.
