Product Description

Laser welded Fin Tube specification:

laser-welded fin tubes Outer diameter of pipe is 8.050.0 mm

laser-welded fin tubes outer diameter of the fin is 17.0 80.0 mm

Flippers are in between 513 fins / inch

The fin are 5.0 17 mm

Wings in thickness are 0.4 1.0 mm

Maximum pipe length is 12.0 m

Laser welding fin tube or High Frequency Welded Fin Tube, Longitudinal Finned Tube has automatic welding process, saving labor cost; secondly, laser welding fin strong, strong, high tensile strength test qualified.Laser welding efficiency is higher.

Advantages of laser-welded fin tubes

1. Laser welding fin tube (wing tube) wing machine has a high degree of automation, the welding of wing to pipe and the winding of pipe synchronization

2. Welding rate is 100%, the laser welding of fin tube fin is firm, and the welding strength exceeds 600MPa.

3. Precision of laser welding pipe finishing machine is 0.05mm

4. Contact resistance is 0, to realize the efficient heat transfer of the spiral fin tube through laser welding.

5. Save on production costs.Laser welded fin tube (fin tube) is less than 2.5mm.Compared with the fin tubes with high-frequency welded helix (spiral), the heat transfer area is increased by about 50%, which reduces the material cost and reduces the volume of the Heat Exchanger.

6. Advantages are decisive over traditional MAG / HF welding.The complete connection between the fin tube and the base tube brings about excellent heat transfer, and the thermal performance of the fin tube increases by 2.5-fold.Continuous welding prevents the incision effect, thus avoiding the formation of v-shaped corrosion and cracks when the fin tube may swing.The heat of base metal is low and the travel speed is up to 20m / min.Minimizes the thermal impact region in the substrate tube.Thus, it does not include the complete melting of the tube and the associated metallurgical transition of the parent metal.


Thin and continuous ideal seam

The area affected by heat is small

The welded parts change color slightly

The microstructure of the tubes and the heat sink varies very little

High heat joint

Since high welding integrity between the tube and the sink is avoided, gap corrosion is avoided to improving safety

Laser welding is performed in a protective atmosphere, so that there are no impurities in the weld


power plant

Cooling tower or cooling water recooling equipment with dry, dry / wet or wet operation

Flue gas cooling and heating in the flue gas desulfurization washer (FGD) and denitrification equipment (DENOX)

chemical industry

Various heat exchangers used for the cooling and heating of liquids and gases
