Product Features
ASTM A179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Due to their excellent thermal conductivity, mechanical properties, and cost-effectiveness, these tubes are highly preferred for making fin tubes.
- Excellent thermal conductivity ensures efficient heat transfer between the fluid inside the tube and the fins
- Cost-effective compared to other materials like stainless steel or copper alloys
- Ideal for large-scale industrial applications

Performance in Radiator Applications
- Enhanced Heat Transfer: Increased surface area allows for more efficient heat dissipation
- Strong Mechanical Bond: Excellent contact between fins and tube minimizes thermal resistance
- Durability: Superior resistance to thermal cycling and mechanical stress
- Corrosion Resistance: Suitable for harsh environments and corrosive fluids

Common Applications
- HVAC Systems for heating and cooling applications
- Industrial Radiators in power plants and manufacturing facilities
- Automotive Radiators for engine cooling
- Oil Coolers in hydraulic systems

Embedded G-type fin tubes are critical components in radiators due to their enhanced heat transfer capabilities, durability, and thermal stress resistance. Their embedded fin design ensures reliable performance in HVAC systems, industrial radiators, and automotive cooling applications.
