Laser Welded Finned Tube Product Description:
Laser welded Fin Tube in the process of use is mainly used for civil wall-hung boilers, industrial boilers, etc., in the operation is mainly the use of its foreign technology, its main advantage in contact with the thermal resistance of zero, the whole equipment compared to high-frequency welding has a large finned ratio, light weight, assembled Heat Exchanger volume compact characteristics, more energy efficient and environmental protection, to meet the emission requirements.
Laser Welding Fin Tube Manufacturing Process:
Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser and metal, metal absorption laser into heat to make the metal melt after the formation of cooling crystallization welding.
Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:
1.Most Efficient:
Making thermal calculations does not have to involve an added weld wire or its splatter and so contributes and promotes to greater heat transfer efficiencies
2.Lighter:
Because the laser process does not use a foreign weld wire, there is no added weight. Only the fin or rib and the pipe
3.Full Penetration of Weld:
Due to the laser process, the entire length of the fin and pipe become “one metal” as there is no added weld wire or the required shield gas for the welding process.
4.No Gap Between Fin and Pipe Wall:
There is no void between the fin root and pipe wall which can cause crevice corrosion, an attack that usually takes place in a very tight gap between two surfaces. The gap can promote cold spots and therefor corrosion.
5.Precise, Distortion Free Welds:
Laser is precision tuned without interference of wire or shield gas. Complete melt of the fin to pipe connection along the entire length of the fin
6.Better Weld Control for Joining Dissimilar Metals:
Precision tuned per application
7.Less Splatter:
Cleaner and smoother surfaces will promote better heat transfer, less pressure drop and less opportunity for particulate buildup, no matter how small the blemishes appear to be.
8.Uniform Root Hardness:
Other welding methods can leave uneven hardness throughout the fin to pipe configuration.
Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:
1.thin, continuous weld seam
2.small heat-affected zone
3.only slight discoloration weld site
4.only slight microstructural change in tube and fin
5.high utilization of heat for forming the seam
6.increased safety because of the avoidance of crevice corrosion due to the high weld integrity between tube and fin
7.no impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere
Laser Welded Finned Tube(Stainless Steel Welded Pipe) Applications:
1.Power Plants
2.Chemical Industry
3.Heat Recovery Plants
4.Heat Industry
