Abstract
A method of reforming the fins of a finned tube is disclosed. The method comprises forming a tube having a plurality of internal longitudinal fins with a V-notch at the tip of the fins, and reforming the fins of the tube over a shaped plug, in long lengths, to spread the tips of the V-notch so that the tips of the fins are wider than the fin thickness.
