Disadvantages of high frequency welded finned tubes

January 14, 2023

The laser welding machine for Spiral Finned Tube is composed of high-power automatic laser pickup machine, full-automatic CNC fixture, automatic feeding machine and other auxiliary equipment. Murphy will soon talk about five characteristics of Laser Welding Of Spiral Finned Tubes:

1: The thickness of base tube can be 0.8-1.5mm, and the thickness of fin can be 0.3-1.5mm. Compared with other processes, the material cost is greatly saved.

2: High Penetration Rate can prevent gap corrosion, prolong service life and reduce heat transfer and heat resistance.

3: Break through the limitation of materials and use different materials for processing.

4: It is easy to reprocess and can be directly curled and bent.

5: The welding heat affected zone is small and the metallographic change is small, which makes it possible to process small diameter Finned Tubes.

Finned tubes are widely used in power and chemical industries. Many helical heat transfer surfaces or threaded tubes can be considered finned tubes. It has a significant effect on expanding the heat transfer area and promoting turbulent flow, and has a greater impact on single countercurrent heat transfer and phase change convective heat transfer. The structure of Finned Tube Heat Exchanger is basically the same as that of general shell and tube Heat Exchanger.
