ASTM A106 Gr. B Carbon Steel High Frequency Welded /HFW Spiral Fin Tube
High frequency welded / HFW finned tubes are used to heat the steel strip and the outer surface of the steel tube until the plastic state or melting by using the skin effect and proximity effect of the high-frequency current while the steel strip is wound around the steel tube, and the welding is completed under a certain pressure when the steel strip is wound. This kind of high-frequency welding is actually a solid phase welding. Compared with inlaying, brazing (or overall hot galvanizing) and other methods, it is good in terms of product quality (high welding rate of fins, up to 95%), productivity and automation. High frequency current is adopted, and winding is carried out at the same time

Advantages of high-frequency welded finned tubes
1. The installation is simple and economical. The length of high-frequency welding spiral finned tube can reach 6m, reducing the connection points, making the installation economical and fast, and reducing the probability of water leakage at the connection.
2. The maintenance is simple. After the installation of high-frequency welding spiral finned tube, the maintenance is basically unnecessary.
3. High efficiency. High frequency welding of spiral finned tube is the full contact welding between fins and steel pipes. The heat dissipation area is more than 8 times that of smooth tube. The internal is smooth and the internal water flow resistance is small.
4. Long service life, high mechanical strength of the combination of fins and pipes, and tensile strength of more than 200Mpa. The inside and outside of the pipes are all hot-dip galvanized.
