Laser welding fin tube

High-precision laser welded fin tubes are the same as HFW fin tubes, using steel strips or stainless steel strips to be directly welded on the tube surface, but using high-precision laser welding. The welding penetration between fins and tubes is close to 100%, which is much better than HFW. Can improve heat transfer efficiency much more than bare tubes. These finned tubes are often used under vibration conditions due to the tight welding of the fins to the base tube. Fin types include serrated fins and flat fins.

Material:
Laser fin coil heat exchangers can be based on different tubes and strips, such as stainless steel, copper, copper-nickel, aluminum, aluminum alloys.

Performance:
Laser finned tube coils have excellent performance, corrosion resistance, compact structure and reduced energy consumption.

process:
Laser welding process, 100% welding, can be rolled or rolled.
