Yuhong Group's Welded Helical Solid Finned Tubes are manufactured 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, ensuring 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 creates the strongest fin-to-tube attachment in the industry, with excellent heat transfer characteristics, low fin-side pressure drop, and minimal change in grain microstructure.
U-bend fin tube is a type of heat exchanger tube bent into a U-shape to increase surface area for heat transfer. The tube is typically lined with fins to further enhance heat transfer capabilities, making it ideal for HVAC systems, refrigeration units, and industrial process equipment.
