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 obtaine…
