Extruded Fin Tube Stainless Steel ASTM A213 TP304 For Air Cooled Heat Exchanger
Extruded Fin Tube Stainless Steel ASTM A213 TP304 For Air Cooled Heat Exchanger
Description:
Extruded fin tubes are manufactured by inserting a smooth stainless steel core tube into an aluminum sleeve. The aluminum sleeve is then extruded and compressed onto the core tube, forming strong, solid fins with excellent thermal contact. This process ensures superior heat transfer efficiency, mechanical strength, and long service life, making the product ideal for high-performance air-cooled heat exchangers.
