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

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:

Fin Material – Aluminium Strip (Al1060):

Mechanical Properties:

ASTM A249 TP304L Base Tube:

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.
