Serrated Welded Fin Tube For Machinery Coolers

High Frequency Welded Fin Tube Product Description:

Helical Fin Tube provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers where clean flue gases are encountered. Helical finned Tubes are manufactured in both Solid and Serrated win profiles.

Helical Solid Finned Tubes are produced by helically wrapping continuous fin strip tube. The fin strip is wounded spirally onto the tube and welded continuously with a High Frequency Electrical process to the tube along the spiral root. The fin strip is held under tension and confined laterally as it is formed around the tube, thereby ensuring that the strip is in forceful contact with the tube surface.  A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter, using the gas metal arc welding process.

For a given pipe or tube size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height and/or number of fins per inch of length.

This welded steel finned tube configuration can be used for practically any heat transfer application, and is particularly suited to high temperature, high pressure applications.   

The important features of this configuration are efficient, effective bond of fin to tube under all conditions of temperature and pressure, and ability to withstand high fin-side temperatures.

A continuous helical fin is attached to the base tube by high frequency electric resistance welding in order to give an efficient and thermally reliable bond.

High Frequency Finned Tube Manufacturing Process:

The steel fin (solid or serrated) is helical wound and continuously welded to the tube by high frequency electric resistance welding. This produces a homogeneous, clean and continuous fin-to tube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.

The welding process enables the combination of any grades for studs and tube: carbon, alloy, stainless steels and high nickel alloys. Alloy steel pipes are stress-relieved after studding, according to the relevant specifications for the class and grade of steel used. 

High Frequency Welded Fin Tube(Electric Resistance Welded Pipe) Advantages:

1.Simple and economical installation High frequency welding spiral fin tube are with zero connection point, so that the installation is more economical, fast, and reduce the probability of leakage at the joint.

2. Easy maintenance. After installation, high-frequency welded spiral fin tube doesn’t need additional maintenance.

3. High efficiency High frequency welding spiral fin tube is full contact welding between fin and steel tube whose heat dissipation area is more than 8 times of bare tube. In addition, the smooth internal wall reduces water flow resistance as well.

4. Long service life, Fin and pipes are combined with high mechanical strength whose tensile strength is more than 200 Mpa. Both inside and outside of the tube are treated with hot dip galvanized processing.
