What are the requirements for purging treated containers with steam or compressed air/nitrogen, and how can it be ensured that the anti-corrosion coating is not damaged?
It should not exceed the pressure for the container’s airtightness test. . . Generally, steam drying is done first, followed by nitrogen drying
There are no special requirements; it’s the same as a normal purge
