L-Fin Tubes

TEK-FINS produces L-foot finned tubes using Aluminum strip that is manufactured to form

an "L" shape and then mechanically wound around the base tubes. The foot of the fins are mechanically joined together and cover the base tube forming a mechanical bond.  Additionally the tube ends are fastened to avoid any potential unrolling. 


The L-foot fin type is formed under tension driving the contact pressure of the foot of the fin

onto the base tube to provide satisfactory heat transfer properties.  The foot of the fin considerably enhances the corrosion protection of the base tube by increasing the strength of the bond.   


TEK-FINS is capable of providing L-Fins using your tubes or we can quote your job with tubes

included in the price.  The L-Fin is designed to work in process applications to 350°F.
