THE HEART OF BEST HEAT EXCHANGER IS FINNED TUBE. IT IS MANUFACTURED ON SPECIAL FINNING MACHINE  TO PROVIDE ALMOST A PERMANENT BOND BETWEEN THE FINS & TUBE  IN ORDER TO GET MAXIMUM EFFICIENCY AND LONG LIFE AS PER CLINTS SPECIFICATION

TYPES :

SMOOTH FINS

ARE AVAILABLE IN SMOOTH AND CRIMPED CONFIGURATION FOR PARTICULAR TEMPERATURE AND APPLICATION

PLAIN FINS : THE PLAIN FIN IS WOUND AROUND THE CORE TUBE  WITHOUT THE FOOT. THE TUBES AND THE FINS ARE PREFERABLY OF SAME MATERIAL. RECOMMENDED FOR  MAXIMUM TEMPERATURE -2000C

L FINS : DEFORMATION OF THE STRIP ' L ' SHAPE GIVES   OPTIMUM  CONTACT IN A FORM OF FOOT ON THE BASE TUBE TO MAXIMISE HEAT TRANSFER PERFORMANCE.

 RECOMMENDED MAXIMUM TEMPERATURE -2600C

G FINS : THE STRIP IS TENSION WOUND IN THE GROOVE OF BASE TUBE. THIS ENSURES THAT MAXIMUM HEAT TRANSFER IS MAINTAINED AT HIGH TUBE METAL TEMPERATURE.

 RECOMMENDED MAXIMUM TEMPERATURE-4500

CRIMPED FINS:

BY CRIMPING THE FOOT OF THE FINS , THE AREA OF CONTACT BETWEEN THE TUBE  AND FINS IS INCREASED . FIN IS TACK WELDED TO THE BASE TUBE AT EACH ENDS OF FINNED SECTION.
