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.
