L Fin (or wrapped fin):The fin is wrapped around the tube and secured at each end. Gives some surface protection to the tube. Used for moderate temperature cooling applications. Upper temperature limit: 120°C

LL Fin (or Overlapped Fin):The fin is wrapped around the tube with an overlapping foot and secured at each end. Gives good surface protection to the tube. Used for moderate temperature cooling applications. 

Upper temperature Limit: 180°C

KL Fin (or Knurled L fin):The fin is wrapped around the tube and the foot is rolled into the outer surface of the pre knurled tube and secured at each end. Gives good surface protection to the tube and improved heat transfer compared to the L or LL type fin. Used for moderate temperature cool applications.Upper Temperature limit: 250°C

G Fin Tube (or Embedded Fin):Fin is embedded into the outer wall of the tube, but gives no surface protection. In general use for continuous process applications; ie refineries, petrochemical, fertilizer and gas plants. Upper temperature limit: 450°C
