Carbon Steel ASTM A179 G Type Embedded Fin Tube For Air Cooler

Carbon Steel Fin Tube ASTM A179 G Type, Embedded Fin Tube, For Air Cooler

Introduction

This G-Type Embedded Fin Tube is manufactured with a carbon steel seamless tube (ASTM A179) as the base and high-purity aluminum strip (Al1060) as the fin material. The G-type design features fins mechanically embedded into a groove cut in the base tube, offering superior mechanical bonding and enhanced heat transfer efficiency. It is ideal for air-cooled heat exchangers used in demanding industrial applications.

Fin – Al1060 (Aluminum Strip)

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

Mechanical Properties

ASTM A179 Base Tube

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


Advantages

  • Strong Fin Bonding: The G-type embedding method ensures fins are mechanically locked, preventing loosening under vibration or thermal cycling.

  • Excellent Heat Transfer: Increased surface area significantly boosts air-side heat exchange efficiency.

  • Corrosion Resistance: Aluminum fins protect against atmospheric corrosion, prolonging service life.

  • Long Lifespan: Ideal for high-dust and high-temperature environments like refineries or petrochemical plants.

  • Maintenance-Friendly: Fin integrity remains stable over long operation periods.

Applications

  • Air Coolers in:

    • Petrochemical Plants

    • Oil Refineries

    • Power Generation Facilities

    • Offshore Platforms

    • Gas Processing Plants
