Carbon steel finned tube

Carbon steel finned tubeAs the name suggests, it is a finned tube made of carbon steel, which can be processed by winding, high-frequency welding, laser welding, and other techniques.

Carbon steel finned tubeWhen the process is winding, the fins are in an inverted Y-shape. It is to fix the base tube on a 360 ° rotating transmission winding device, and then select different types of fixtures according to different blade heights and distances. The fins are strip shaped and initially formed by passing through the fixture, relying on mechanical tension to wrap the fins around the base tube in one go.

Process of carbon steel finned tubeWhen welding at high frequency, the strip steel is spiral welded onto the base pipe on an automatic welding production line. This structure has a welding rate of over 98%, is sturdy and corrosion-resistant, and is suitable for harsh working conditions.

Carbon steel finned tubeCharacteristics:

1. The sheet spacing is relatively large, ranging from 3.2-8mm, and the sheet thickness is generally between 0.2-3mm. The unit heat transfer area is small, and the contact thermal resistance is relatively high.

2. Due to the fact that carbon steel finned tubes rely on uniform bottom wrinkles to stand on the base tube, the bottom wrinkles can have a certain turbulence effect on the air outside the tube, which is beneficial for enhancing heat transfer. At the same time, the bottom wrinkles also increase the gas side resistance, and dust accumulation is prone to occur at the wrinkles, which increases the difficulty of removing condensate and cleaning dust. Attention must be paid when selecting.

3. Single metal finned tubes also have the characteristics of easy material selection, low processing difficulty, and light manufacturing cost.

Carbon steel finned tube: Carbon steelThe fins of the base tube are not completely covered, and the base tube is exposed to air, which can easily cause corrosion.
