Laser Welded Stainless Steel Fin Tube:
The laser welded fin tube uses laser welding technology, is 99%-100% fully welded, has Higher heat transfer ability compared to HF welding and Wrapped fin tube, has 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 tubes using laser welding. Because the products have good thermal efficiency and good non-corrosibility, it's always applied to petroleum & metallurgy & chemical & Industrial waste heat recovery & Civil gas water heater, radiator & electric water heaters,s and others.
Although the unit price of laser welding is higher than high-frequency welding or winding without welding, laser welding finned tube has a better welding penetration rate and better heat transfer efficiency, considering long-term use it is a maximum energy saving to reduce the cost of use, so lase welding tube is the most economical.

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