Product Description

THERMAL SOLUTIONS----FINNED TUBES

About Finned Tubes

A fin tube is a tube that has lots of fins around the outside surface. These fins act as a filter and a mechanism to transfer heat from the material inside the tube to the outside space or vice versa. Fin tubes are used in applications that require a transfer of heat from a hot fluid to a colder fluid through the tube's wall.

Quality Control

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.
