A non-penetrating nozzle cannot be used to:

• A. Cover a crack
• B. Enhance structural integrity
• C. Replace a damaged area
• D. Seal a leaky joint

Answer: (A)

A non-penetrating nozzle is designed to attach to the outer surface of a vessel without compromising its integrity by creating a hole or penetration. This type of nozzle typically serves purposes such as providing access for inspection or allowing for the addition of instrumentation without affecting the primary structure of the pressure vessel. The main reason a non-penetrating nozzle cannot be used to cover a crack is that its intended function is not for repair. Covering a crack would generally require addressing the underlying material and ensuring that the integrity of the vessel is restored, which a non-penetrating attachment cannot accomplish. Crack repairs typically involve methods that ensure the material is reinforced or filled, which goes beyond just covering the issue. In contrast, enhancing structural integrity and sealing a leaky joint might involve techniques that could include non-penetrating methods, depending on the context. Replacing a damaged area, however, requires more comprehensive repair actions that involve penetrating the material and reinforcing the structure, which is not achievable with a non-penetrating nozzle. Understanding the purpose and limitations of various types of nozzles and repair techniques is crucial for maintaining safety and compliance in pressure vessel management.
