Passivation

Before commissioning a plant, passivation is commonly carried out for long pipes
and tanks. Valve blocks are usually excepted from this.
Passivation is typically performed using nitric acid (HNO

3

) at approx. 80 °C (176

°F) at a concentration of 3 % and a contact time of 6 to 8 hours.
The ultimate temperatures, chemicals, concentrations and contact time to be
used must be determined by the plant operator along with its chemical supplier.
