Internal fin tube heat exchanger
Unique Internal, Spiraled Fins
Our revolutionary, Internally-Finned tubes deliver the same long life and superior heat transfer capability as our Straight-Wall tubes, they literally pay for themselves. By simultaneously stirring the gas flame and increasing the inside surface area to capture more heat, these finned tubes reduce fuel consumption by approximately 10%.

Inner finned tube or internally-finned tube is heat transfer pipe with fins formed on the inside. Such flat and smooth tubes have a larger internal surface area compared to smooth pipe (formal steel pipes with a circular cross section) and possess superior heat transferability. Finned tubes are used in applications involving the transfer of heat from a hot fluid to a colder fluid through a tube wall. The rate at which such heat transfer can occur depends on three factors:
(1) the temperature difference between the two fluids;
(2) the heat transfer coefficient between each of the fluids and the tube wall;
(3) the surface area to which each fluid is exposed. By extending the surface of heat transfer tubes , inner finned tube with longitudinal ribs increases efficiency of heat transferring performance. Compared with the normal smooth tube, heat transferring coefficient of inner finned tube can be increased 3-4 times.
For the sake of personalized demands, customer can decide fin shape and dimensions by discussion with us.
In fact, inner finned tube is our strength. One long-time customer uses our pipes for a heat transfer device that cools insulation oil in an electrical transformer.
