The image below shows the area of a coking unit at a petrochemical company that has been newly constructed or renovated; it depicts the condition after one year of use without applying an undercoat during the anti-corrosion treatment of the steel structure.

To become rusted like this in just one year – how much acid must be present in this environment.
