After what type of change is a pressure test normally conducted?

• A. Alterations and major repairs
• B. Repairs
• C. Rerates
• D. Repairs and alterations

Answer: (A)

A pressure test is typically conducted following alterations and major repairs to ensure the integrity and safety of the pressure vessel. When a vessel undergoes significant changes, such as modifications to its structural components or replacement of critical parts, it may affect how the vessel behaves under pressure. The pressure test serves as a means to verify that these changes do not compromise the vessel's ability to safely operate within its designed parameters. Conducting a pressure test after alterations helps to confirm that the vessel can withstand its operating conditions and that there are no leaks or weaknesses present as a result of the modifications. While repairs also require validation, the focus on alterations and major repairs reflects the greater potential for changes in the vessel's structural integrity and performance characteristics. This emphasizes the importance of conducting thorough safety assessments, particularly when significant work has been performed, to minimize risks associated with pressure operation.
