Carbon Steel Seamless Tube A179, Wound Fin Tube, L Type Fin Tube, For Air Cooler

Introduction

This L Type Wound Fin Tube is made using ASTM A179 carbon steel seamless tube as the base tube and a high-purity aluminum strip (typically Al1060) as the fin. The L-type fin is tightly wound and mechanically bonded onto the base tube to maximize contact surface, promoting efficient heat transfer and corrosion resistance. It is a reliable solution for air cooler systems in industrial plants.

Chemical Composition

Base Tube – ASTM A179 (Carbon Steel)

Element	C (%)	Mn (%)	P (%)	S (%)
Content	0.06–0.18	0.27–0.63	≤0.035	≤0.035

Fin – Al1060 (Aluminum Strip)

Element	Al (%)	Si (%)	Fe (%)	Cu (%)	Zn (%)
Content	≥99.6	≤0.25	≤0.35	≤0.05	≤0.05

Mechanical Properties

ASTM A179 Base Tube

Property	Value
Tensile Strength	≥325 MPa
Yield Strength	≥180 MPa
Elongation	≥35%
Hardness	≤72 HBW

Advantages

Tight Wound Fins: L-type fins are tightly wrapped with overlapping feet, offering enhanced heat transfer and good corrosion protection at the base.
Economical: Simple and cost-effective design for moderate operating conditions.
Improved Heat Efficiency: Enlarged surface area increases air-side heat exchange capacity.
Moderate Durability: Suitable for low to medium pressure and temperature environments.
Quick Delivery & Easy Manufacturing: Faster production times compared to embedded or extruded types.

Applications

This L Type Fin Tube is typically used in:

Air Cooled Heat Exchangers (ACHE)
HVAC Units
Gas Coolers
Oil Coolers
Process Cooling Systems

Installation Zone in Air Coolers:
Mainly used in convection zones or finned bundles where ambient or forced air flows across the fins to cool process fluid inside the tubes.
