Which R goes into UG-27? Which E do you take? Which document do you open in the open-book portion? Here each API 510 topic fits on one page: the drawing, the calculation in fixed steps, and a box that tells you where to look in your code PDFs. 62 illustrated pages.

One topic per page, the drawing that shows you how it's done, and boxes with what you need to know:

These are real pages from the book. The table of contents is the full one: 11 parts and 58 topics.
You've read the metal loss section three times. You close your notes...
...and you're not sure anymore which reading comes off which, or where the mils come in. It was just lines of text.

Here metal loss is one page, drawn on the shell wall: the previous reading, the current reading and 0.500 in − 0.440 in = 0.060 in, 60 mils gone.
And on the pages next to it, each calculation has its own: short-term and long-term corrosion rate, remaining corrosion allowance, remaining life and the inspection interval.
First you understand why it's done that way. Then the order sticks on its own.

The exam, API 510 essentials, corrosion rates and intervals, ASME VIII pressure calculations, testing and toughness, repairs and rerating, PCC-2 repair methods, welding, NDE, damage mechanisms and inspection practice: 62 pages, all drawn
Imagine this:
Instead of rereading half a page about the UW-3 joint categories without being able to picture them...
...you open the page and find one vessel with every weld marked: A longitudinal, B circumferential, C flanges, D nozzles.

And corrosion rates, remaining life, hydrotest pressure, repairs and WPS review turn into drawings and tables you can read at a glance.
You stop repeating and start understanding.
That's what The API 510 Exam Sketchbook does: 62 drawn pages in 11 parts, 58 exam topics, one per page, and every topic page tells you where to look in the open-book PDFs. You see it in order, so you can redo it in order.
Because what your brain sees organized, it remembers.
What the exam covers, the Effectivity Sheet and Body of Knowledge, closed-book vs open-book strategy, eligibility, fees and recertification.
Scope and exclusions, key definitions and who does what, inspection plans and RBI, internal, on-stream and external inspection, records and reports.
From two UT readings to the next inspection date, in the same steps every time: metal loss, short-term and long-term rate, remaining corrosion allowance, remaining life and the internal and external interval.
See every weld on one vessel, A to D, and know which RT level and joint efficiency it takes. Then shell and head thickness, static head, vessel vs part MAWP and where corrosion allowance goes.
Hydrostatic and pneumatic test pressure, impact testing, MDMT and exemptions, weld sizes at openings and nozzle reinforcement.
Repair vs alteration, who authorizes and approves, repair welding and PWHT alternatives, testing after repairs, rerating and the nameplate.
Insert plates, external weld buildup, fillet welded patches, hot taps and in-service welding, and NDE in lieu of pressure testing.
Reviewing a WPS, PQR tests and acceptance, welder qualification, processes and discontinuities, metallurgy and heat treatment.
Article 1 general requirements, radiography and IQI selection, liquid penetrant, magnetic particle yoke and prod, and UT thickness per SE-797.
Brittle fracture, amine, caustic and chloride cracking, wet H2S, high-temperature hydrogen and sulfidation, CUI and atmospheric corrosion, acid corrosion and erosion.
RP 572 vessel inspection practices, relief device types, relief device inspection and testing, and material verification with PMI.
At the end of the book: A 'where to look' box on every page, pointing to the paragraph in your open-book PDFs.

40 original exam-style problems on corrosion rate, remaining life, intervals, shell and head thickness, MAWP, static head and test pressure, each one worked step by step, so you practice the math until it comes out in the same order every time.

The term on the front and a one-line definition with a tiny sketch on the back. Print them and go over the vocabulary in short breaks between shifts.

The whole Body of Knowledge in order, every calculation in the same fixed steps, and a 'where to look' box on each page for the open-book portion.
A quick drawn review of what you see in the plant: hydrotests, repair vs alteration, PCC-2 repair methods and the RP 571 damage mechanisms on the sheet.

For anyone preparing for the API 510 Pressure Vessel Inspector exam: in-service inspectors, NDE and QA/QC technicians moving into vessel inspection, and anyone retaking it. It's not a beginner's book about what a vessel is, and it covers API 510 only, not API 570 or 653. Check the index above to see every topic.
On the API 510 Body of Knowledge and the API 510 Publications Effectivity Sheet that API publishes for the current exam windows. Before you start, check on the API website which edition applies to your exam date. The book doesn't reproduce code text, tables or figures: each page points to the paragraph to look up in your own documents.
No. It's an independent study book, not affiliated with or endorsed by API, ASME or Prometric. It doesn't give a certificate or PDH credits: the API 510 certification only comes from passing the API exam.
No. For the open-book portion you still need the code documents listed on the Effectivity Sheet. It doesn't replace a prep course, your company's procedures or a qualified inspector's judgment: it's a clearer way to review.
No. The 40 problems in the Calculation Workbook are written for this book. They aren't official API 510 exam questions; they're there so you practice the method.
Yes. The PDF is high resolution, so you can print the whole book or only the parts you want to keep on hand. The 250 Terms on Cards are made to be printed.
30-day guarantee: tell us what didn't work and we'll refund 100%.
You don't have to reread the same page hoping it sticks this time.
You don't have to memorize formulas you can't picture.
And you definitely don't have to walk into the exam not knowing where to start.
One last thing before you decide: you already have the code PDFs and the notes. What was missing is the order. 62 drawn pages, a “where to look” box on every one, and 2 free books to practice and review.
