To achieve the mirror surface finishing of the outer surface of a pipe, a new idea was applied to the ironing process. An aluminum pipe was set into a steel container with a very smooth surface. The inside of the pipe was ironed and the outside was flattened at high pressure with a small slip of the metal on the container surface. The experiment was carried out with various reductions and different viscosities of oil. Higher reductions and lower oil viscosity produce more excellent surfaces, and the finest surface has nearly the same topography as the inner surface of the container has.
