Advantage:adding surface area to a smooth tube while maintaining the same outside diameter.
Use: in standard shell and tube baffles and tube sheets.
Method: from a smooth tube, fins with a particular geometric form without removing material; this plastic deformation causes an increment of heat exchange efficiency, and allows to reduce the heat exchanger size.
