Abstract
A finned tube 1, Fig. 2, is disclosed together with a process and an apparatus for making the tube. The finned tube has T-shaped fins 2 extending from the outer surface of the tube, the base 3 of the fins extending radially from the tube. The fins extend continuously and unbroken (e.g. helically) around the tube outer surface. The fin shape is formed progressively by rolling discs 8, Fig. 3, from a smooth tube 1'. Thereafter the end of each fin is smoothed by a roller 13 and circumferentially notched by a roller 14 which forms the fins into a Y-shape. A final flattening roller 11 bends the fins into a T-shape. <IMAGE>
