ASTM B111/ASME SB111 C70600 Copper-Nickel Low Finned Tube
Overview:
A low Fin Tube is essentially a single integral tube — made of a singular material — with a smaller fin of about 1/16th of an inch of fin height. The fin is in the tube wall. They are generally used in liquid to liquid or liquid to gas applications such as coolers, condensers and chillers.
We use a proprietary die to form helical grooves into the outside diameter of the product to create the fin. Low fin tubes are available in any manufacturable or formable tube alloy — including copper, copper-nickel, stainless steel, carbon steel, brass, and more.
The beauty of the small fin height of a low finned tube is the outside diameter of the fin does not exceed the outside diameter of the tube. You can put a fin tube through a tube sheet that is just barely larger than outside diameter of the tube, but with a small fin that allows for greater heat transfer than a smooth tube.
Another advantage to low fin tubes is the ability to increase enhanced surface on the inside of the tube through internal groves or spirals, optimizing heat transfer capability.
Low fin tubes allow for a high fin count — up to about 40 fins per inch, down to about 19 fins per inch.
