• Carbon (C): 0.06% - 0.18%
• Manganese (Mn): 0.27% - 0.63%
• Phosphorus (P): ≤ 0.035%
• Sulfur (S): ≤ 0.035%

Mechanical Properties

ASTM A179 tubes possess mechanical properties that make them suitable for various industrial applications, ensuring durability and reliability under different operating conditions. Key mechanical properties include:

• Tensile Strength: Minimum 325 MPa (47,000 psi)
• Yield Strength: Minimum 180 MPa (26,000 psi)
• Elongation: Minimum 35% in 2 inches (50 mm)

Material:
ASTM A179: Standard specification for seamless cold-drawn low-carbon steel heat-exchanger and condenser tubes.
Low Fin: The fins are integrally rolled out of the tube wall itself, creating a continuous fin that is part of the tube.

Key Features:
Enhanced Surface Area: The low fins increase the surface area available for heat transfer, enhancing the efficiency of the heat exchanger.

Durable Construction: Since the fins are part of the tube itself, they are less likely to become damaged or detached compared to externally attached fins.

High Heat Transfer Efficiency: The increased surface area and direct material continuity improve thermal conductivity.
Compact Design: Low fin tubes allow for a more compact heat exchanger design, saving space while maintaining high efficiency.

Applications:
Heat Exchangers: Widely used in various heat exchanger applications, including condensers, evaporators, and economizers.

Industrial Processes: Suitable for power plants, chemical processing, oil and gas refineries, and HVAC systems.

Refrigeration and Air Conditioning: Used in systems requiring efficient heat exchange in a compact form.

Technical Specifications:

Tube Diameter: Available in various diameters depending on the specific application requirements.

Fin Height: Typically low fin tubes have fin heights of around 1.5 to 6 mm.

Fin Pitch: The number of fins per inch can vary, affecting the overall surface area and heat transfer efficiency.

Advantages of Low Fin Tubes:
Improved Heat Transfer: Significantly enhances the heat transfer coefficient compared to plain tubes.
Cost-Effective: More cost-effective in terms of materials and manufacturing compared to other types of finned tubes.
Maintenance: Easier to clean and maintain due to the integrally formed fins.

Conclusion

ASTM A179 carbon steel low fin tubes are crucial for industries requiring efficient and reliable heat transfer. Their enhanced surface area, combined with the excellent thermal conductivity and mechanical properties of low-carbon steel, makes them an ideal choice for heat exchangers, condensers, boilers, and various other thermal systems.
