Product Description

 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.

 Ordering and Delivery

For a given pipe or tube size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height, fin thickness and number of fins per inch.

If the whole transfer surface area of the finned tube is A and the transfer surface area of the tube is A0, then nominal the ratio A/A0 should be 5 to 12.
