ASME SA179 Carbon Steel Tube with Aluminum Fins Extruded Fin Tube for Air Cooled Heat Exchangers

The Extruded Fin Tube is a high-efficiency heat transfer component widely used in air cooled heat exchangers, radiators, and cooling systems operating under demanding thermal conditions. This product features a carbon steel base tube manufactured to ASME SA179 and integrally extruded aluminum fins, ensuring superior thermal conductivity, mechanical strength, and long-term reliability.

By mechanically extruding the aluminum sleeve onto the steel tube, the fin material becomes permanently bonded to the tube surface. This process creates excellent thermal contact with no air gaps, significantly enhancing heat transfer performance while maintaining structural integrity.

• Integral Fin Bonding
  Aluminum fins are extruded directly onto the ASME SA179 tube, eliminating thermal resistance and ensuring stable performance over time.

• High Heat Transfer Efficiency
  Optimized fin geometry increases surface area, improving air-side heat dissipation in air cooled heat exchangers.

• Corrosion Resistance
  Aluminum fins provide natural corrosion resistance in atmospheric environments, extending service life.

• Mechanical Strength
  Carbon steel SA179 base tube offers excellent pressure resistance and mechanical durability.

• Thermal Cycling Stability
  Strong fin-to-tube bond prevents loosening or fin separation during repeated heating and cooling cycles.

The extruded fin tube is produced by placing an aluminum sleeve over the ASME SA179 steel tube. Through a controlled extrusion process, the aluminum is plastically deformed and bonded tightly onto the tube surface. This method results in uniform fin formation and exceptional fin-to-tube contact, which is critical for efficient heat transfer.
