Re: [MW:27956] Nitrogen purging of Duplex S32205 pressure vessel during transportation

2205 duplex is extremely resistant to corrosion.

You do not need N2-purging at all

We have Duplex S32205 material of pressure vessel. Is nitrogen purging during transportation required or not? Per my understanding, the main aim of introducing the nitrogen is to prevent the cylinder breathing in atmospheric moisture during long term storage.
