Low Fin Tube ASTM A179 Carbon Steel Seamless Fin Tube Heat Exchanger
Low finned tubes expand the heat transfer area by adding ribs outside the tube. Compared with light tubes, they have a larger surface area while consuming the same metal material, thereby improving the heat transfer coefficient.
The increase in heat transfer area per unit volume reduces the number of tubes required for finned tube heat exchangers under the same heat load, and the diameter or height of the shell can be reduced, saving space.
