Low Finned TubeFinned TubeWelded Finned Tube
Profins can supply either solid or serrated welded finned tubes. These tubes are manufactured specifically to suit the high temperature environment found in furnaces/boilers and waste heat recovery equipment.

Our high frequency serrated fin is a metal strip that has been serrated or cut and then helically wound around the specified tube. The fin is welded to the tubular base using the high frequency weld process.

The fin can be applied to a wide variety of tubular material with configurations to suit your requirements.

Integral low fin tube has the advantage that it can improve the thermal performance of a heat exchanger without the necessity for changing shell size, flow arrangement or the repositioning of piping. The external surface of the tube is increased by the formation of "low fins" by direct extrusion from the material of the base tube.
