KL Carbon Steel Tube Aluminum Fin Heating Transfer 

L/LL/KL Finned Tube Product Description: - KL Finned Tube（Knurled Aluminum Tubing） This is manufactured similar to L fin except that the base tube is knurled before wrapping the 'L' shaped fin strip. After wrapping the fin strip, the fin foot is also knurled on the base tube to increase the bonding between the tube & fin. This will result in increased heat transfer performance. Maximum Operating Temperature- 260 deg C Tube Material - No theoretical limit. Fin Material - Aluminium or copper - L Finned Tube Aluminium fin strip is formed to L shape and then tension wound to the base tube. Maximum operating temperature for L fin is 150 deg C.
