Product Overview
The ASTM A249 TP304 stainless steel L-fin tube is a welded austenitic stainless steel tube wrapped with helically wound L-type fins, typically made from aluminum or stainless steel. The L-shaped fin is tightly wound under tension to ensure close metal-to-metal contact, which improves heat transfer performance.
Chemical Composition

Fin Material Options:
- Aluminum (Al1060): High thermal conductivity, lightweight, suitable for general cooling applications.
Mechanical Properties
| Property | Value (TP304) |
|---|---|
| Tensile Strength | ≥ 515 MPa |
| Yield Strength | ≥ 205 MPa |
| Elongation | ≥ 35% |
| Hardness | ≤ 90 HRB |
Key Advantages
- Excellent Heat Transfer: The L-fin structure maintains tight contact, improving thermal efficiency.
- Corrosion Resistance: TP304 provides strong resistance to moisture, chemicals, and oxidizing agents.
- Mechanical Strength: Welded stainless steel tube offers durability under operating pressure.
- Cost-Effective: More economical than seamless alternatives for general service conditions.
- Customizable: Fins available in various heights, thicknesses, and materials per design needs.
Industrial Applications
Used extensively in air-cooled heat exchanger units (fin fan units) for:
- Oil Refineries
- Petrochemical Plants
- Gas Processing Facilities
- Power Plants
- Offshore Cooling Systems
- Fertilizer Plants
Specific Role in Air Coolers:
Installed in the convection section where ambient air is blown across the finned surface to remove heat from process fluids flowing inside the tube.
