Upgrading or modifying pressure relief systems under API-510 requires a thorough analysis to ensure that the new system meets the current operating conditions and safety standards. This includes recalculating the required capacity of relief devices, verifying the materials of construction for compatibility with the contents and conditions, and performing pressure tests after installation to confirm the system's effectiveness.

API-510 addresses the challenges of corrosion under insulation (CUI) by recommending specific inspection and maintenance strategies. This includes guidelines for the periodic removal of insulation for visual inspection and testing, use of appropriate materials that resist moisture accumulation, and the application of coatings that inhibit corrosion. Additionally, API-510 advises on the use of advanced non-destructive testing techniques, such as real-time radiography or ultrasonic testing, to detect signs of corrosion without removing insulation, thus reducing inspection costs and downtime.
