According to API 580, multiple API inspection codes include provisions for RBI. Section 4.3 of API 580 clearly states:
“The RBI methodology is recognized in the API inspection codes — API 510, API 570, and API 653 — as an acceptable method to determine inspection intervals.”
Each of these codes outlines both the requirements and limitations for using RBI in their specific contexts:
API 510 — for pressure vessels
API 570 — for piping systems
API 653 — for aboveground storage tanks
On the other hand:
API 573 is a recommended practice for the inspection of fired heaters and does not include formal RBI provisions.
API 578 focuses on Positive Material Identification (PMI) and is unrelated to RBI methodologies or requirements.
Therefore, the correct selection includes:
✔️API 510
✔️API 570
✔️API 653
