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
Laser welded finned tube is the most advanced technology products, it has irreplaceable advantages
1: The thickness of the base tube can be between 0.4 and 0.8 mm, and the thickness of the fin can be between 0.3 and 0.8 mm, 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 the small diameter finned tube.
Heat exchange pipe and condensing pipe material, should have excellent heat transfer performance, but also should have good corrosion resistance, erosion resistance, abrasion resistance performance, but also should have good strength and stiffness and plasticity, easy to process and manufacture
