What is the time limit on a sodium nitrite wet lay-up?

• A. 24 hours
• B. No time limit
• C. 90 days
• D. 1 year

Answer: (B)

The correct response is that there is no time limit on a sodium nitrite wet lay-up. This method is utilized to protect the internal surfaces of a system, especially in cases where a prolonged shutdown is anticipated. The sodium nitrite solution provides effective corrosion protection for an extended period, allowing systems to remain in lay-up without the need for immediate further action or monitoring. This feature is particularly advantageous because it allows for flexibility in maintenance schedules or unforeseen delays without compromising the integrity of the materials involved. In contrast, some other methods of corrosion protection may have strict time constraints to ensure efficacy, but sodium nitrite's ability to provide long-lasting protection makes it unique and valuable in this context.
