## What is API 510 Pressure Vessel Exam?

Prepare for the API 510 pressure vessel inspector exam with question practice, code-reference exercises and an interactive inspection workbench.

EXPLORE THE VESSEL
Select the shell, heads, welds or pressure-relieving device. Connect each component to relevant inspection questions and code references.

WORK THE THICKNESS HISTORY
Compare initial, previous and current readings at a condition monitoring location. Change the values to see long-term and short-term corrosion rates and follow the remaining-life calculation.

FIND THE GOVERNING CLAUSE
Practice locating a reference in your own code book, then reveal the locator and answer the question. Search the question bank by inspection task, standard or clause.

PRACTICE AND REVIEW
Work through 613 questions, use hints when you need them and revisit answers that need another attempt. Practice closed-book and open-book mock sections and review your results.

STUDY ON YOUR TABLET
Use the landscape inspection workbench to keep the vessel and related questions side by side. Compare thickness readings with the calculation without switching screens.

Topics include pressure vessel inspection, corrosion, remaining life, thickness, welding, examination and pressure relief. Reference exercises use your own code books; the app does not include the full standards.
