Pickling and Passivation of Steel Pipes www

Pickling leaves a greater change to the steel pipe. Passivation uses either nitric acid or citric acid that are not recognized as being as aggressive as the acids used in pickling. Passivation does not typically go below the surface of the metal and does not change the properties of the metal.
