What is needed when only a nozzle is pressure tested instead of the entire vessel after an addition?

• A. Approval from just the Inspector
• B. Approval from just the Engineer
• C. Approval from either the Inspector or Engineer
• D. Approval from both the Inspector and Engineer

Answer: (C)

When a nozzle is pressure tested independently of the entire vessel following an addition, it's essential that the pressure test is validated to ensure safety and compliance with relevant standards. The requirement for approval from either the Inspector or Engineer arises from the fundamental roles these individuals play in the testing process. The Inspector is responsible for ensuring that the test is conducted according to applicable codes and standards, verifying that the test method, procedure, and results meet safety criteria. The Engineer, on the other hand, provides insight into the design and structural integrity implications of the tested nozzle and the overall system. Having the flexibility to obtain approval from either the Inspector or the Engineer acknowledges that both parties can assess the pressure test's validity and results. This two-pronged approach enhances safety and quality control, ensuring that all potential risks are evaluated adequately before proceeding with further operations. In this context, the options requiring approval from just one party or both are less suitable because they do not reflect the collaborative importance of both roles in ensuring the integrity and safety of pressure vessels after modifications.
