ASME SA179 Carbon Steel Wound Fin Tube KL Type With Aluminium 1060 Strip
ASME SA179 Carbon Steel Wound Fin Tube KL Type With Aluminium 1060 Strip
Product Description
The ASME SA179 carbon steel wound fin tube (KL type) is manufactured by tightly winding an Aluminium 1060 strip around the base carbon steel tube. The foot of each fin strip is knurled (K) into the tube surface to improve bonding strength, and then the strip is tension wound (L) along the tube length to ensure close contact and excellent thermal conductivity. This construction provides a reliable combination of mechanical strength and heat transfer efficiency, ideal for air coolers and other heat exchanger systems.
