ASTM A179 Carbon Steel Fin Tube L Type With Al1060 Fin Strip For Heat Exchanger
ASTM A179 Carbon Steel Fin Tube L Type With Al1060 Fin Strip For Heat Exchabger
Product Overview
The ASTM A179 Carbon Steel Fin Tube L Type is produced by wrapping Aluminum 1060 fin strips onto a low-carbon seamless steel tube. The "L Type" attachment method mechanically locks the base of the aluminum strip onto the tube surface, ensuring tight contact and efficient heat transfer. This design is widely used in heat exchangers, condensers, and air coolers, where corrosion resistance and thermal conductivity are critical.
