Tubo com aletas longitudinais manufacturer Datang is 20 Years Factory Fin Tube Manufacturers and Supplier, and can provide ODM and OEM services.

Longitudinal finned tube is a component that increases the heat exchange area by welding metal fins on the surface of the base tube. The fins are arranged perpendicular to the axis of the base tube and are mainly used to enhance the heat exchange efficiency. ‌

Structural features of longitudinal finned tubes

‌Fin direction‌: The fins are arranged perpendicular to the axis of the base tube. This structure can guide the fluid to generate turbulence, increase the contact area between the fluid and the fins, and thus improve the heat exchange efficiency. ‌

‌Manufacturing process‌: High-frequency welding technology is usually used to firmly weld the fins to the base tube to ensure heat transfer efficiency and structural strength. ‌
