Specification :

Fin Tube Products, Inc. offers a root soldered fin to tube attachment. This method of soldering, available on our larger diameter tubing provides a void free fin to tube joint. This method of attachment decreases the amount of solder used compared to a dip process. This increases the heat transfer of the finned tube. When dipped in solder a full coat/ film of insulating solder is formed over the entire fin and tube surface. Soldered fin tubing is good in temperatures up to 375° F.
