High Frequency Welded Spiral Finned Tube

High Frequency Welded Spiral Finned Tube is a heat exchange element that uses high frequency welding technology to spirally wrap steel strips (fins) and weld them to the outer wall of a steel tube. It is mainly used to enhance heat transfer efficiency. ‌

Core Features of High Frequency Welded Spiral Finned Tube

‌High Frequency Welding Process‌: Use the skin effect and proximity effect of high frequency current to heat the steel strip and the outer surface of the steel tube to a plastic or molten state to achieve a firm bond. ‌

‌Spiral Structure‌: The steel strip is spirally wrapped around the outer wall of the steel tube, effectively increasing the heat exchange area (up to several times to dozens of times that of a light tube) and reducing flow resistance. ‌

‌Corrosion Resistance‌: Suitable for high temperature, high pressure and corrosive environments, commonly used in industrial scenarios such as boilers and waste heat recovery. ‌

Main Applications of High Frequency Welded Spiral Finned Tubes

‌Industrial Field‌: Used in waste heat recovery and equipment cooling systems in industries such as power, metallurgy, and petrochemicals. ‌

‌Advantages‌: Compared with traditional light tubes, it has higher heat dissipation efficiency, more durable structure, and convenient installation.
