Laser Welded Finned Tube Product Description:

 

The laser welding process is carried out under the protective atmosphere, and no impurity of the weld seam.

The fin strip is welded continuously and spirally wound onto bare tube. And the tube and fins are bonded together by using lase welding technique. 100% welding between fin and base tube without using any filler material.

The Laser Welded Fin Tubes are widely applied in fired heaters, heat exchangers, boilers, economizers, pre-heaters, coolers, heat pipes, heaters, etc.

 

Laser Welded Finned Tube

 

Laser Welding Fin Tube Manufacturing Process:

The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using advanced laser welding technique.

Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:

1.Thin and continuous ideal seams

2.Small heat affected area

3.Slightly discolored welding parts

4.The tubes and fins have only slight microstructure changes

5.High heat forms seams

6.Since the high welding integrity between the tube and the fins is avoided, the crevice corrosion is avoided, thereby improving safety

7.Laser welding is carried out in a protective atmosphere, so the weld is free of impurities

 

Fin Tube

 

Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:

1.a high degree of automation, automatic fins laser welding machine can realize one-time completion of welding, synchronous winding make the fin foot and the pipe depth of weld.

2.laser welding, high firmness, high binding force. Laser welding is metallurgical bonding, welding strength is more than 600MPa.

3.laser welding machine with high accuracy, welding a 8 meter long fin tube with a precision of 0.05mm.

4.the heat transfer coefficient can be improved greatly by laser welding.

5.laser welding finned segment length is less than or equal to 2.5 mm, heat dissipation area than the high frequency welded pipe (distance is more than or equal to 4.5 mm) increased by nearly 50%, greatly reducing the material of the tube, also can decrease the change of the volume of the Heat Exchanger.
