Product Description

Datang Tube is one of the top five manufacturers and suppliers of wound finned tubes in China. It has a production and processing workshop of 20,000 square meters and can produce more than 50,000 meters of high-quality finned tubes per month.

With an aim to increase the heat exchanging efficiency, It's usually to extend the surface area (or internal surface area) by adding fins onto a tube, which, through this manufacturing process, would greatly improve and upgrade the heat transferring efficiency of heating tube, it's called Finned Tube or Fin Tubes.


Application:

Oil and gas refineries

Petroleum, chemical and organic compound industries

Natural gas treatment

Steel creating trade

Power plants

Air acquisition

Compressor coolers

The Finned Tubes are essentially Tubes with increased surface area.
The amount of heat transferred from a particular surface is directly correlated to the surface area available for the heat to transfer.
Hence, increasing the heat transfer area as a whole increases the heat transfer efficiency.

In a Finned Tube the Surface Area of the Tubes is increased by providing Fins on the Heat Exchanger.
These fins can be of various types, made of various materials and designed in various ways depending on the end requirement.

Laser welding finned tube is processed by laser welding machine. Laser welding is a welding method that irradiates a high-intensity laser beam onto the metal surface.

Through the interaction of the laser and the metal, the metal absorbs the laser light and converts it into heat, melting the metal to form a cooling crystal.

Laser welding machine is the most advanced laser welding equipment for finned tubes.

Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welding finned tubes are superior to traditional cooling tubes.

The laser welding finned tube has a fully automatic welding process, saving manpower costs; secondly, the laser welding fin is firm, strong, and the test with high tensile strength is qualified. Laser welding is more efficient.
