What are the advantages and disadvantages of high frequency welding and laser welding of finned tubes?

Suzhou Elmart answers for you: At present, there are many kinds of finned tubes in China, mainly high-frequency welded finned tubes. Although it is more advanced than inlaying and brazing methods in product quality and production automation, there are still many shortcomings in heat exchange efficiency and dust-proof convenience due to factors such as the root of high-frequency welded finned tube is not easy to penetrate and wrinkle.

Laser welded finned tube is the most advanced product at present, which is irreplaceable.

Advantage.

Product features:

(1) 100% welding without filler.

(2) Using gas protection, welding has no defects such as air holes and sand holes.

(3) Different base pipes and belts

(4) It can be bent and coiled.

(5) No welding change, thin weld seam and small metallographic change.

Advantages:

(1) prevents crevice corrosion and has long service life.

(2) Easy to clean, suitable for food and pharmaceutical industries.

(3) The ideal heat transfer area is small and the investment cost is reduced.

(4) Matching with the process, reducing the use and maintenance costs, reducing costs and reducing investment costs.

(5) The fin part can be bent quickly and conveniently to reduce deformation.

(6) The pipeline is almost unaffected by the welding process, so the weight and space of the heat exchanger can be reduced and the unsafe factors in the manufacturing process can be reduced.

1: The thickness of the base pipe can be 0.8- 1.5mm, and the thickness of the fins can be 0.3- 1mm, which greatly saves the material cost compared with other processes.
