A low finned tube machine is specialized equipment used to manufacture low finned tubes by rolling fins directly from the outer wall of a plain tube. During the process, the tube material is plastically deformed to form integral low-height fins, creating a one-piece structure with excellent heat transfer performance.

Because the fins are formed from the base tube itself, there is no welding and no fin detachment risk. Low finned tube machines are widely used for producing tubes for condensers, evaporators, and heat exchangers, especially where compact size and high efficiency are required.
