What is the minimum pressure required for a nitrogen blanket lay-up?

• A. 2 psig
• B. 5 psig
• C. 10 psig
• D. 15 psig

Answer: (B)

The minimum pressure required for a nitrogen blanket lay-up is 5 psig. This pressure is crucial to ensure that the nitrogen blanket can effectively displace any potential moisture and oxygen in the system, preventing corrosion and other forms of damage during periods of inactivity. A blanket of nitrogen serves not only to maintain a non-reactive atmosphere within the system but also to provide a slight overpressure that keeps contaminants out. If the pressure were lower than 5 psig, it would not adequately create the necessary barrier to atmospheric conditions, thereby increasing the risk of corrosion and degradation of the equipment. Additionally, pressures that are too low could lead to nitrogen being unable to fully blanket the system, allowing air to enter and mix with whatever is being stored or protected. Therefore, maintaining a nitrogen pressure of at least 5 psig is a key factor in ensuring the integrity and longevity of the equipment during lay-up periods.
