Miniature Finned Tubing

Celebrating 20+ Years Since 1993

Fin Tube Products, Inc. is a leader in the development and production of miniature finned tubing. Finned tubing can be supplied in sizes descending from 1/4" to a diameter as small as .015". Fin counts can reach up to 142 fins per inch on the hypodermic size tubing.

Fins are helically wound and then secured with a Soldered or FINBRAZE® fin to tube attachment. The miniature fin tubes are generally used for low temperature cryogenic, or biomedical applications. A typical cryogenic use would be a coiled heat exchanger supporting a Joule-Thomson port (J-T port).

FTP will work with customer engineers to develop prototype finned tube constructions for pilot evaluations.
