Welded Helical Solid Finned Tubes manufactured with by helically wrapping fin strip on edge around the tube circumference and continuously welding the fin strip to the tube. the use of high-frequency current skin effect and proximity effects, the steel and steel pipe surface heating, until the plastic state or melting, in the winding strip under a certain pressure Completed solid phase welding.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.
Can be used for practically any heat transfer application, and is particularly suited to high temperature, high pressure applications with high fin-side temperatures. Solid fin can be supplied with thicker fins than the serrated fin, which can be an important factor when dealing with extremely corrosive or erosive environments.
