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

Base Tube: ASTM A249 TP304 Stainless Steel

Element Content (%)
C ≤ 0.08
Mn ≤ 2.00
Si ≤ 0.75
P ≤ 0.045
S ≤ 0.030
Cr 18.0 - 20.0
Ni 8.0 - 11.0
Fe Balance

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.
