Which inspection practice is recommended to ensure degradation is not missed?

To effectively ensure that degradation in a pressure vessel is not overlooked, the recommended practice is to start at one end and work methodically to the other. This systematic approach allows inspectors to maintain a consistent and comprehensive examination path, which helps ensure that no areas are skipped or inadequately inspected. By following a defined workflow, any signs of wear, corrosion, or other forms of degradation can be identified and documented more accurately.

Additionally, this methodical technique minimizes the likelihood of overlooking potentially problematic areas, as each section of the vessel is given equal attention. It contrasts with random inspection or focusing solely on high-stress areas, which can leave other critical areas vulnerable to unnoticed deterioration. Thorough external reviews are important but should be complemented with a systematic inspection process to fully assess the vessel's condition. This balanced approach ultimately enhances the reliability and safety of the equipment being inspected.
