Laser welded copper finned tube,copper base tube C12200

Five characteristics of laser welding finned tubes:

1: The thickness of the base tube can be 0.8-1.5 mm, and the thickness of the fin can be 0.3-1 mm, which greatly saves material costs compared to other processes.
2: High penetration rate, can prevent crevice corrosion, prolong service life, and reduce heat transfer resistance.
3: Break through the material limit and can use different materials for processing.
4: Easy secondary processing, can be directly coiled and bent.
5: The welding heat-affected zone is small, and the metallographic change is small, making it possible to process small diameter fin tubes.

Advantages of laser welding finned tube

a、The laser welding finned tube (finned tube) fin machine has a high degree of automation, and the welding of the fin to the tube and the winding of the tube are synchronized
b、100% welding rate, laser welding finned tube and fins are strong, the welding strength exceeds 600MPa.
c、The precision of laser welding tube finishing machine is up to 0.05mm
d、0 contact resistance, achieve high efficiency of heat transfer of spiral finned tube by laser welding.
e、Save production costs. The laser welding finned tube (finned tube) has a smaller fin spacing, less than 2.5mm. Compared with the high frequency welded spiral (spiral) finned tube, the heat transfer area is increased by about 50%, which makes the material cost Reduced, volume reduced heat exchanger.
d、The advantages over conventional MAG / HF welding are of decisive importance. The complete connection between the fin and the base tube brings excellent heat transfer, and the thermal performance of the fin tube is increased by 2.5 times. Continuous welding prevents the notch effect, thereby avoiding the formation of v-corrosion and cracks under the condition that the finned tube may swing. The heating of base metals during welding is low and the travel speed is up to 20m / min. Minimize the heat affected zone in the base tube. Therefore, it does not include the complete melting of the tube and the related metallurgical transformation of the parent metal.

Laser Welded Finned Tube Application

This kind of heat exchanger is widely used in industrial fields such as petrochemical industry, aviation, vehicles, power machinery, food, deep and low temperature, atomic energy and aerospace. For example, superheaters, economizers, air preheaters, condensers, deaerators, feedwater heaters, cooling towers, etc. in boiler thermal systems; hot blast stoves, air or gas preheaters in metal smelting systems, Waste heat boilers, etc.; evaporators, condensers, regenerators in refrigeration and low-temperature systems; heating and cooling equipment widely used in the petrochemical industry, sugar liquid evaporators and pulp evaporators in the sugar industry and paper industry, These are numerous examples of heat exchanger applications.
