API Pressure Vessel Inspector is an official American Petroleum Institute (API) exam, catalogued under exam code API-510. Passing it awards the Authorized Pressure Vessel Inspector certification at the Professional level. It also connects with API 570 Piping Inspector, API 653 Storage Tank Inspector, API 571 Damage Mechanisms, API 576 Pressure Relieving Devices. It is built for candidates with ambitious aims, and the credential it grants is recognized accordingly.

API Pressure Vessel Inspector spans 5 official domains, led by Repairs, Alterations, Rerating, and Mechanical Integrity (16%), Damage Mechanisms and Corrosion Assessment (22%), and Fitness-for-Service, RBI, and Pressure Testing (12%). The complete outline sits above; before getting down to business, look through the whole contents quickly so every later practice session has context.

The API Pressure Vessel Inspector exam presents 170 (140 scored + 30 unscored pretest; 110 closed-book + 60 open-book) questions within 450 (total exam day: 7.5 hours; 165 min closed-book + 225 min open-book + 45 min break). A practical tip from successful candidates: mark the most difficult questions during practice, exchange notes on them with friends, and repeat them until they stop being difficult. The ActualVCE engine makes that loop fast, and the clock stops being a threat.

Passing API Pressure Vessel Inspector requires 550 (scaled score, range 200–750), and official registration costs $875 (API member) / $1,125 (non-member) USD. Retakes bill the full $875 (API member) / $1,125 (non-member) USD again, so verify readiness before booking: when your ActualVCE practice scores clear the requirement repeatedly, including on questions you once marked as difficult, you are ready.
