Root Soldered Fin to Tube Attachment
Root Soldered Fin to Tube Attachment

Celebrating 20+ Years Since 1993

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.
