High accuracy Laser welded fin tube same with HFW fin tube,use steel or stainless steel strip directly welded to tube surface but by high accuracy laser welded.Welding penetration is nealy100% between fin and tube,much better than HFW.Can improving heat transfer efficiency much more than bare tube.Due to the tight welding of the fins to the base tube, and these finned tubes are often used in vibrating conditions.Fin type have Serrated fin and flat fins.
Materials:
laser finned coil heat exchanger can base on different tube and strip, such as, Stainless steel, Copper, Cupro-Nickel, Aluminum, Alloy Aluminum.
Performances:
laser finned tube coil are high performance, corrosion resistance, compactness, reduced energy consumption.
Processes:
Laser welding process, 100% welded, can be rolling or coiling.
Base tube material:
stainless steel, carbon steel, copper alloy,alloy steel (No theoretical limit)

High Frequency Welded fin tube also called solid type fin tube,use steel or stainless steel strip directly welded to tube surface by HFW.Can improving heat transfer efficiency much more than bare tube.Due to the tight welding of the fins to the base tube, these finned tubes are often used in vibrating conditions.Fin type have Serrated fin and flat fin.
L type fin tube, The fin is helically wound around the base tube forming a strong mechanical contact between the tube and fin, thus improving the heat transfer efficiency.Also named Wrap On fin tube. This also give considerable corrosion protection to the base tube.
KL type fin tube same as L fin tube,except that the base tube is knurled before application of the fin foot.Also named Wrap On Knurled type fin tube.After application,the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between fin and tube,Resulting in improved heat transfer efficiency.
