Lord Fin Tube--ASTM A 179 L type finned tube
ASTM A179 L Type Finned Tubes
Superior Heat Transfer Solution for Industrial Applications
Why Choose ASTM A179 L Type Finned Tubes?
ASTM A179 L type finned tubes represent an advanced heat transfer solution designed for efficiency and durability in demanding industrial environments. These specialized tubes combine the strength of low-carbon steel with the superior thermal conductivity of aluminum fins, creating an optimal balance for heat exchange applications.
Key Advantage: The L-foot design provides maximum contact between fin and tube, ensuring excellent heat transfer while maintaining mechanical stability under thermal cycling conditions.
L-Foot finned aluminum tubes are manufactured using a thin aluminum fin strip that is helically wound around the circumference of an ASTM A179 base tube. The unique feature is the L-shaped foot (1/16" wide) formed on one side of the fin strip, which gives this fin type its name.
During the winding process, the fin strip is tensioned to forcefully seat the L-foot on the tubes outer surface, creating a tight mechanical bond without the need for additional adhesives or welding in many applications. The standard fin spacing is typically 10 fins per inch, though this can be customized based on specific thermal performance requirements.
