Yuhong Group's Welded Helical Solid Finned Tubes are manufactured with by helically wrapping fin strip on edge around the tube circumference and continuously welding the fin strip to the tube. 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 Yuhong Group's unique gas metal arc welding (GMAW) process. This weld process creates the strongest fin to tube attachment in the industry, excellent heat transfer characteristics, low fin-side pressure drop and little to no change in grain microstructure and physical characteristics even when 3%-9% chromium tubes are used.
