... to deep-purple discoloration on the metal, avoiding the formation of black scale. It was also recommended that the scale and discoloration of the welds at the outlet and HAZs be removed by abrasive blast cleaning and that the interior of the completed tanks be passivated, using either 22% HNO 3 at 60 °C...

In addition, the rusting of the steel and the lifting of the mill scale can render subsequent abrasive blasting easier, rather than increase costs as is sometimes claimed. From the many investigations we have carried out, we offer the following truism, which we do...
