API 570 Piping Inspector Exam Prep
Prepare for the API 570 Piping Inspector certification exam with 1,500 original practice questions built to API’s current Body of Knowledge and the publications effectivity sheet for the February 2027 and June 2027 exam windows — API 570 5th Edition, ASME BPVC 2023 Edition, ASME B31.3 2024, ASME B16.5 2020, and the current editions of RP 571, RP 574, RP 576, RP 577, RP 578 and ASME PCC-2. API publishes no topic weighting for this exam, so the bank’s portion sizes are a PassProfessor allocation set from the Body of Knowledge’s emphasis — they are not API’s weighting. This program sits in our Industrial Inspection Exam Prep collection alongside API 510 Pressure Vessel Inspector practice on the same shared hub.
What’s included
- 1,500 original practice questions covering every Body of Knowledge area, including the calculation families the exam requires (corrosion rates, remaining life, inspection intervals, joint and casting quality factors, minimum thickness and MAWP of corroded pipe, blank thickness, pressure-test pressures, impact-test determinations and thermal expansion) in both US customary and SI units
- Nine portion practice drills (10 questions each) — one per portion, so you can target your weakest area
- A full 170-question timed simulation (390 minutes) — the same number of questions and testing time as the real exam
- Detailed explanations for every question, with the full computation shown on calculation items
- A free 12-question sample — no account needed to try it
Price: $79 for 6 months of access.

About the real API 570 exam
The API 570 exam has 170 questions (140 scored and 30 pretest) in a 7.5-hour exam day: a closed-book part (110 questions, 165 minutes) testing everyday working familiarity, a 45-minute lunch, and an open-book part (60 questions, 225 minutes) in which PDF copies of the effectivity-sheet sections are provided on the exam computer. The exam is taken in person at a Prometric centre only — API 570 is excluded from remote testing. Eligibility depends on your education: from one year of qualifying experience with a degree in engineering or technology, up to five or more years without formal education, each including one year of supervision or performance of API 570 inspection activities, gained within the last ten years while employed by, or under contract with, an authorized inspection agency. Certification runs for three years.
How passing works: API publishes the passing standard as a scaled score of 400 on a 200–500 scale. Because the score is equated across forms, the number of correct answers that corresponds to 400 varies by form — it is not a percentage, and 400 is not “80%”.
Fees: exam fees are published by API — confirm the current fee at api.org before you apply. PassProfessor is a study provider only: we do not certify inspectors and we do not enrol candidates for the official exam — you apply through API’s ICP Portal and sit the exam at Prometric.
How our practice scoring works
Our simulation presents 170 questions in 390 minutes — the real exam’s published size and testing time — in a single sitting. It does not reproduce the Prometric open-book PDF environment, the two-part sitting, or any alternative item types the real exam may use. Because API’s passing standard is a scaled score rather than a percentage, our simulation is scored against a 70% practice benchmark — a PassProfessor benchmark only, not API’s passing standard. Use the portion drills to find weak areas and the simulation to build timing and calculation speed.
PassProfessor is an independent study provider and is not affiliated with or endorsed by API. API and API 570 are marks of the American Petroleum Institute. All practice questions in this course are original works written for this course; none of them are API exam questions, and no code text, tables or figures from API or ASME publications are reproduced.
