KL type fin tube

KL type finned tubes are the same as L type finned tubes except that the base tube is knurled before using the fin feet. Also called wrapped knurled finned tube. After use, knurl the fin feet into the corresponding knurls on the base tube to enhance the bond between the fins and the tube, thereby improving heat transfer efficiency.

The fins are spirally wrapped around the base tube, creating strong mechanical contact between the tube and fins, thereby increasing heat transfer efficiency. This also provides considerable corrosion protection to the base pipe.
Maximum operating temperature: 500 F (260 C)
