Introduction

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. This type of fin tube is widely used in fin fan air coolers in refineries, petrochemical plants, gas compression stations, and power generation systems.


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

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.


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.
