API
API 510
Pressure Vessel Inspection Code
The in-service code for pressure vessels: inspection intervals, thickness monitoring and remaining life, repairs, alterations and rerating. Where Section VIII governs how a vessel was built, API 510 governs everything that happens to it afterwards.
This is an explanation, not the standard. PipingInspector is not affiliated with API and reproduces no part of the document. Always work to the current edition of the standard itself and to your project specification.
