ASTM A249 Fin Tube

Stainless Steel Fin Tube ASTM A249 TP304L L Type With Aluminium Strip For Air Cooler


Description:

This finned tube consists of a welded stainless steel base tube (ASTM A249 TP304L) and an L-type wound aluminium fin (typically Al1060). The L-type fin is helically wound onto the base tube under tension to ensure tight contact and excellent thermal conductivity.



Chemical Composition:

Base Tube – ASTM A249 TP304L:

Element Content (%)
Carbon (C) ≤ 0.035
Manganese (Mn) ≤ 2.00
Phosphorus (P) ≤ 0.045
Sulfur (S) ≤ 0.030
Silicon (Si) ≤ 1.00
Chromium (Cr) 18.0–20.0
Nickel (Ni) 8.0–12.0

Fin Material – Aluminium Strip (Al1060):

Element Content (%)
Aluminium (Al) ≥ 99.6
Iron (Fe) ≤ 0.35
Copper (Cu) ≤ 0.05
Others ≤ 0.15


Mechanical Properties:

ASTM A249 TP304L Base Tube:

Property Value
Tensile Strength ≥ 485 MPa
Yield Strength ≥ 170 MPa
Elongation ≥ 35%
Hardness (HRB) ≤ 90



Key Advantages:

  • Corrosion Resistance: TP304L offers excellent corrosion resistance, especially in humid or slightly corrosive environments.

  • Lightweight, High Conductivity Fins: Aluminium fins provide superior thermal transfer while keeping the weight low.

  • Enhanced Heat Transfer Surface: The L-type fin design increases the external surface area for improved heat dissipation.

  • Cost-Effective Solution: Welded tube and wound fin design provide performance at a lower cost compared to extruded fin tubes.


Typical Applications:

  • Air Cooler Units

  • HVAC Systems

  • Dry Cooling Towers

  • Condensers

  • Petrochemical Cooling Systems


Function in the Air Cooler:

  • Process fluid (such as oil, water, gas, or steam) flows inside the stainless steel base tubes.

  • Air flows across the aluminium fins on the outside of the tubes.

  • The fins increase the external surface area, allowing more efficient heat dissipation to the air.

  • The L-type fin tightly wound onto the base tube ensures good thermal contact and efficient heat transfer.

  • The stainless steel tube provides corrosion resistance and strength under temperature and pressure.
