Introduction
This high frequency welding is actually a solid phase welding. Compared with inlay, brazing (or overall hot-dip galvanizing) and other methods, it is more advanced in terms of product quality (the welding rate of fins is high, up to 95%), productivity and automation.
There are many types of finned tubes, and new varieties are constantly emerging. According to the processing process, they can be broadly classified according to the following aspects.
1) Rolled fin tube (extruded fin tube).
2) Welding fin tube (high frequency welding fin tube, submerged arc welding fin tube).
3) Roll forming fin tube.
4)、Set forming fin tube.
5) Casting finned tubes.
6) Tension-wound finned tubes
7), Flanged tube.
