Extruded Finned Tube , ASTM A179 Carbon Steel Seamless Heat Exchanger Fin Tube

ASTM / ASME SA179 Carbon Steel Extruded Finned Tube Heat Transfer Tube

Carbon Steel ASTM A179 extruded finned tubes are specialized heat exchangers designed to enhance thermal performance by increasing the surface area available for heat transfer. The fins are extruded onto the base tube, which allows for a more secure bond and better thermal conductivity compared to other methods (like welded or glued fins).

• ASTM A179 provides a good balance of strength, ductility, and thermal conductivity.
• Fins: The fins can be made from the same material as the tube or can be constructed from other metals (like aluminum) to improve thermal performance, depending on the application requirements.

Corrosion Resistance of ASTM A179 Extruded Finned Tube

• Surface Treatment: Depending on the application, finned tubes may undergo surface treatments like galvanization or coating to enhance corrosion resistance, especially when used in humid or corrosive environments.
• Material Choice: While A179 is primarily a carbon steel, other materials (like stainless steel or special alloys) can be selected for specific applications requiring greater corrosion resistance.

Installation and Maintenance of ASTM A179 Extruded Finned Tube

• Ease of Installation: A179 extruded finned tubes can often be integrated into existing systems with relative ease, provided proper fitting is used.
• Maintenance Considerations: Regular cleaning may be required to prevent dust or particles from affecting the efficiency of the fins.
