KL-finned tube is also called knurled finned tube. Before winding the fins, the base tube is knurled, or a blade is installed on the winding machine to knurl the base tube. The blade behind is used for winding. Sheeting, knurling and winding are carried out simultaneously.
It is basically the same as the L-shaped fin tube, except that after the fins are wound, the roots of the fins attached to the steel tube will be knurled to strengthen the combination of the steel tube and the fins. This fin type has better bonding rate and heat transfer characteristics than L and LL type fins. The maximum operating temperature is 250℃.
