S/T Trufin in Copper-Nickel Alloys Tube
Type S/T Trufin is designed for boiling and condensing of hydrocarbons and other liquids. Integral helical fins on the outside of the tubes provide an increase in outside surface area, in effect, minimizing a low heat transfer coefficient normally encountered when evaporating a liquid or condensing a vapor. The inside diameter is basically a smooth surface.
