API 572 — Pressure Vessel Inspection Practices

A recommended practice that provides guidance on inspecting pressure vessels operating in petroleum and petrochemical facilities.

Definition

API RP 572 is an American Petroleum Institute Recommended Practice that provides detailed guidance on the inspection of pressure vessels. It covers inspection planning, inspection techniques, damage recognition, inspection locations, documentation and evaluation of common deterioration mechanisms affecting pressure vessels during service.

Why It Matters

API RP 572 promotes consistent inspection practices, improves defect identification and supports effective integrity management of pressure vessels.

In Practice

API RP 572 is intended to support API 510 by providing practical inspection guidance rather than mandatory inspection requirements. It is frequently used together with API RP 571 and API 579-1/ASME FFS-1.

Common Misuse

API RP 572 is a Recommended Practice rather than a mandatory inspection code. It supplements API 510 with practical inspection guidance.
