ASTM A179 L Type Fin Tubes are made from carbon steel, which has excellent thermal conductivity and corrosion resistance. These fin tubes are manufactured using a seamless process, ensuring their uniformity and strength.
L type fin tubes are made of a thin aluminum fin strip which is tightly wound helically around the circumference of the ASTM A179 base tube. The strip is then tightly wound around the tube, with the foot bearing on the outer surface of the tube. L Type Fin Tube is a type of fin tube used in heat exchangers to increase the surface area for heat transfer between the fluid inside the tube and the fluid outside the tube.
