A312 TP347H HFW Fin Tube Manufacturing Process

High-Frequency Welding: The fins are welded onto the base tube using high-frequency electric currents. This process ensures:

• Strong bond: Creates a seamless and durable connection between the fins and the tube.
• Precision: Ensures uniform fin placement and consistent quality.
• Efficiency: A fast and cost-effective production method.
• Surface Treatment: The tubes may undergo additional treatments, such as pickling, passivation, or polishing, to enhance corrosion resistance and surface smoothness.
