Laser Welded Stainless Steel Fin Tube:
The laser welded fin tube use of laser welding technology, 99%-100% fully welded, Higher heat transfer ability comparing to HF welding and Wrapped fin tube, Lower energy consumption, reduced cost of consumables and increased efficiency of the process. widely used in corrosive conditions, such as heat recovery in condensing boilers, and heat exchangers in Industries of Chemical, Petroleum, Petrochemical, Metallurgical, Power, Food and Maritime.
The products are finned tube using laser welding. Because the products has good thermal efficiency and good non-corrosibility, so it's always applied to petroleum & metallurgy & chemical & Industrial waste heat recovery & Civil gas water heater, radiator & electric water heater and others.
Although the unit price of lase welding is higher than high-frequency welding or winding without welding,
lase welding finned tube has better welding penetration rate and better heat transfer efficiency,
considering long term using it is maximum energy saving to reduce the cost of use, so lase welding tube is most economical.

Laser welded finned tubes (fin tubes)
New innovation: Laser welded finned tubes (fin tubes) and tube finning machine:
Laser welded finned tubes (fin tubes) is our new development in fin tubes research, which is able to completely automaticly, mechanically laser weld the fins to tubes with advanced welding quality, comparing to traditional high frequency welded helical (spiral) fin tubes.
The advantages of Laser welded finned tubes (fin tubes):
Laser welded finned tubes (fin tubes) finning machine has high automatic, the welding of fin to tubes and winding on tubes are made synchronously
100% welding rate, Laser welded fin tubes has strong soundness between fins and tubes, welding strength is over 600MPa.
Laser welded tube finning machine has high precision up to 0.05mm
0 contact resistance, high co-efficiency of heat transfer for spiral fin tubes by laser welding.
Save production cost. Laser welded finned tubes (fin tubes) has more small fin pitch, less than 2.5mm, its heat transfer area increase around 50% comparing to high frequency welded helical (spiral) finned tubes, which make material costs decrease largely as well as volume of heat exchanger.
