The ASTM A179 L-type fin tube is primarily used in the tube bundle section of an Air-Cooled Heat Exchanger (ACHE) — commonly known as a fin fan cooler. Within this system, it plays a crucial role in the air-side heat transfer process.
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.06 |
| Manganese (Mn) | 0.27 – 0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Property | Value |
|---|---|
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Elongation | ≥ 35% |
Cost-Effective: ASTM A179 carbon steel is economical for non-corrosive environments.
Efficient Heat Transfer: L-type fin design ensures close metal contact between the tube and the fin for effective thermal performance.
Simple Fabrication: Easy to produce and maintain.
Durability: Wound fins resist vibration and mechanical stress in air cooler operation.
In a refinery, the ASTM A179 Carbon Steel L-Type Wound Fin Tube is typically used in the Air-Cooled Heat Exchanger (ACHE) units, specifically in the tube bundle section of the cooling system.
Hot hydrocarbon fluid (from a column or reactor) flows inside the A179 carbon steel tube.
Aluminum L-type fins wound around the tube surface increase the surface area for air-side heat rejection.
Large axial fans force ambient air across the finned tube bundle.
Heat transfers from the fluid to the tube wall → to the fins → to the air.
The cooled fluid is sent to the next processing step or storage.
