Low Fin Tube

Titanium Low Fin Tube

Low Fin (Integral) tubing is a type of extruded tubing that consists of short low fins. The low fin tube have the advantage of adding surface area to a smooth tube while maintaining the same outside diameter. Low Fin Enhanced tubes can be used in standard shell and tube baffles and tube sheets.

Extruded Low Fin Tubes

This method of construction is very different from cutting grooves onto the tube as is often done by people who are on the lookout for a shortcut or who don’t know any better.


We offer you a broad portfolio of materials and can expand our offering at any time to meet your specific needs regarding thermal conductivity, mechanical properties, or corrosion resistance.

Low-finned tubes solutions are already available in copper, copper-nickel, aluminum, steel, stainless steel, and titanium.

A Low Fin Tube is formed by passing a tube through a set of rollers that form the fins from the parent material of the tube by making it flow in the desired way.


Low finned tubes are a reliable solution for controlling the temperature of gases and liquids, or for evaporating and condensing refrigerants. Thanks to their larger heat transfer surface area, they offer considerable potential to save in terms of materials and fill volumes, especially applicable to air and other gases on the fin-side and a fluid on the tube-side. Applied in heat exchanger for oil refinery and petrochemical plants, condenser and heat exchanger for petrochemical plants, condenser & evaporator for power plants,
