Carbon Steel Finned tube A179 Extruded Fin Tube With L – Type Aluminium 1060/1050 For Air Cooler Heat Exchanger Condense
L Type Finned Tube for Heat Exchanger
L Type Finned Tube is a finned tube made of aluminum fin tape or copper fin tape folded into an L-shaped spiral under tension and wrapped tightly around the outer surface of the base tube. It is combined with two different materials. The tension in the fin strips of the L Type Finned Tube wraps around the tube， causing the fin feet to press forcefully against the tube， holding the fins firmly in place.
Manufacturing Process
Fin strips (usually aluminum and copper) are folded into an L shape and wound under tension on the surface of the base tube. The feet of the fins are connected together and cover the surface of the fins.
