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.
