Overview of extrude finned tubes

The Extruded Fin Tube also known as Bimetallic Fin Tube is one of the most preferred finning processes for various applications.
The fins are manufactured by Extruding the Fins on the Aluminum Muff Tube which is made to Fit with close tolerance over the Base Tube.
The Extruded Fin Tubes or Bi-Metallic Fin Tubes are a type of fin tubes that have extruded fins from the outer surface. The base tube is made to slide inside an outer tube made of copper or aluminum. Then, this assembly of the inner and outer tube is passed through an automatic extrusion machine. During the extrusion process, the fin is extruded from the outer tube to the desired height, thickness, and density configuration.
