Carbon /Stainless/ Alloy Steel High Frequency Welded / HFW Solid Finned Tube
HFW / High-Frequency Welded finned tube. For HFW solid finned tubes, they are specialized tubes commonly used in applications such as boiler, heat exchangers and industrial heating systems. For welding technique of HFW finned tubes, they are produced by welding the edges of a strip (stainless steel, alloy steel, carbon steel), using high-frequency electrical currents to generate heat, which results in a solid weld. For fin attachment: Fins are attached to the tubes to enhance heat transfer surfaces. These fins can be integral (part of the tube) or attached post-manufacturing. Yuhong can also make the drawing according to clients' requirements.
Common Base Material of HWF solid finned tube
HFW solid finned tube is usually made from carbon steel, stainless steel or alloys, each selected based on the required thermal properties and resistance to corrosion and pressure.
Fin Design: Different fin geometries (e.g., circular, square, or serrated) can affect heat transfer rates and flow characteristics, making design choices crucial.
Spacing: The distance between fins can also impact air or fluid flow, influencing overall efficiency.
Performance Features
Heat Transfer Efficiency: The fin design increases surface area, leading to improved heat exchange performance.
Pressure and Temperature Resistance: Capable of withstanding high pressures and temperatures, making them suitable for demanding environments.
Corrosion Resistance: Depending on the material, fin tubes can be designed to resist corrosive environments.
Advantages of high-frequency welded finned tubes
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.
The maintenance is simple. After the installation of high-frequency welding spiral finned tube, the maintenance is basically unnecessary.
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.
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.
