The term for changing an identical item due to corrosion with increased MAWP for the whole system is called?

• A. repair and re-rating
• B. re-certification
• C. retrofitting
• D. replacement

Answer: (A)

In this scenario, the important idea is restoring a corroded item while also updating the system’s pressure rating to a higher MAWP. When you repair the damaged component and then re-rate the entire system to reflect the higher allowable pressure, the process is called repair and re-rating. The repair covers restoring the component’s integrity, and re-rating updates the system’s MAWP to ensure the whole piping network is evaluated against the new, higher rating. Replacement would simply swap the component, but doesn’t inherently imply increasing the system’s MAWP. Retro-fitting suggests a design change or upgrade beyond an identical replacement. Re-certification is about confirming compliance after work, not the act of repairing plus changing the rating.
