About Finned Tubes
With an aim to increase the heat exchanging efficiency, It’s usually to extend the surface area (or internal surface area) by adding fins onto a tube, which, through this manufacturing process, would greatly improve and upgrade the heat transferring efficiency of heating tube, it’s called Finned Tube or Fin Tubes.
