ASTM A213 TP316L Stainless Steel Fin Tube Extruded Type For Air Cooler

ASTM A213 TP316L Stainless Steel Fin Tube Extruded Type For Air Cooler


Product Overview
The fin tube is produced using ASTM A213 TP316L seamless stainless steel tubes with extruded Aluminium 1060 fins. The extrusion process creates a metallurgical bond between tube and fin, ensuring excellent thermal performance, mechanical strength, and long service life in demanding cooling applications.

Advantages of Extruded Fin Tube

  • Excellent corrosion resistance from TP316L stainless steel

  • Superior thermal conductivity of Aluminium 1060 fins

  • Strong integral bond from extrusion process (resistant to thermal cycling)

  • Long service life with low maintenance

  • Easier cleaning compared with L, LL, KL, and G-type fins

Applications in Air Cooler

  • Air-cooled heat exchangers in petrochemical and refinery plants

  • Fin-fan coolers in power generation

  • Condensers and gas coolers in chemical and fertilizer industries

  • Offshore and marine coolers, where corrosion resistance is essential
