ASTM A179 G-Type Embedded Finned Tube , Aluminium 1060 , for Heat Exchangers

The ASTM A179 G-Type Embedded Finned Tube is a high-performance heat transfer component commonly used in industries such as power generation, petrochemical, and HVAC systems. This type of finned tube is designed to enhance heat exchange efficiency by increasing the surface area available for heat transfer.

Key Features:

• Base Tube Material:
  The base tube complies with the ASTM A179 standard, which specifies seamless cold-drawn low-carbon steel tubes. These tubes are known for their excellent heat transfer properties and high mechanical strength.

• Fin Type:
  The G-Type Embedded Fin involves mechanically embedding aluminum fins into a groove cut into the tube's outer surface. This ensures a strong mechanical bond between the fins and the tube, providing excellent thermal conductivity and durability.

• Fin Material:
  The fins are made of Aluminium 1060, a high-purity aluminum material with exceptional corrosion resistance, thermal conductivity, and lightweight properties. Aluminium 1060 is particularly suitable for applications where efficient heat transfer and long service life are required.

• Design Benefits:

  • Enhanced Heat Transfer: The embedded fin design increases the heat exchange area, improving overall thermal performance.
  • Durability: The mechanical bonding ensures a tight connection between the fins and the tube, reducing the risk of detachment under thermal cycling conditions.
  • Corrosion Resistance: Aluminium 1060 fins provide excellent corrosion resistance, even in harsh environments.

• Applications:
  The ASTM A179 G-Type Embedded Finned Tube is widely used in various applications, including:

  • Heat exchangers
  • Air coolers
  • Boilers
  • Condensers and evaporators
