Laser welded finned tubes

Our company has accumulated many years of high frequency welding finned tube, square finned tube, Mosaic finned tube, rolled composite steel and aluminum finned tube experience.

Cb laser welding of spiral finned tube is used in civil, industrial boilers, etc., using German technology, domestic just started, but has a history of more than a decade in Europe, advantage is that the contact thermal resistance is zero, and high frequency welding compared with wing than the big, light weight, the assembly of the characteristics of compact heat exchanger volume, more energy conservation and environmental protection, meet the national discharge requirements.

Laser welding finned Tube materials such as stainless steel, titanium, copper, carbon steel, etc

Domestic finned tube type is various, mainly high frequency welding finned tube, though it is compared with Mosaic, brazing methods, in terms of product quality and production automation is more advanced, but because of the high frequency welding finned tube roots to factors such as penetration and the roots have a fold, lead to the high frequency welding finned tube in deposited in the thermal efficiency and the convenient also has many shortcomings. In view of the above reasons and in response to the national policy on energy conservation and emission reduction.

Laser welded finned tube is the most advanced technology products, it has irreplaceable advantages

1: The thickness of the base tube can be 0.4~ 0.8mm, and the thickness of the fin can be 0.3-0.8mm, which greatly saves the material cost compared with other processes.

2: High penetration rate, can prevent clearance corrosion, prolong service life, reduce heat transfer resistance.

3: Break through the material limit, can use different materials for processing.

4: Easy for secondary processing, direct coil and elbow.

5: The welding heat affected area is small, and the metallographic changes are small, making it possible to process
