ExploreAbout this exam
The API 570 Piping Inspector credential is one of the American Petroleum Institute's Individual Certification Programs (ICP). It is intended for inspectors and engineers who evaluate in-service process piping - the fixed piping systems found in refineries, petrochemical plants, tank farms and similar facilities - rather than newly fabricated pipe. Certification signals that a candidate can apply the API 570 standard alongside its companion documents, including the damage-mechanism reference API 571, the inspection-practices guide API 574 and the piping-inspection-code summary API 578, plus the relevant ASME construction and welding codes. The exam is organized around five content areas: scope, definitions and organization of API 570; causes of deterioration and failure in piping systems; inspection, rating, repair, alteration and rerating of in-service piping; inspection practices, methods and referenced code requirements; and records, reports and repair/replacement documentation. Most successful candidates prepare by reading the current editions of those documents cover to cover, working through calculation and rating problems, and pairing study with field experience on real piping circuits.

What you'll study
About API 570 preparation
Is this site affiliated with API or does it issue the certification?
No. This is an independent study platform. Only API issues the API 570 Piping Inspector certification and administers the exam. All official questions about eligibility, scheduling, fees and scoring must go to API directly through its Individual Certification Programs (ICP) pages at api.org.
What is the exam format?
API 570 is a multiple-choice examination. The exact item count, time allowance and any reference materials permitted during the exam are set by API and are subject to revision, so confirm the current published format on the API ICP page for this certification before you schedule.
How long is the exam and how many questions does it contain?
We do not publish these figures here because they are revised periodically and must come from API's current materials. Check the API 570 certification page under Individual Certification Programs for the current item count and time limit, and plan your pace accordingly once you have confirmed them.
How difficult is the exam?
It is a demanding, code-heavy exam. Questions commonly require you to locate a specific requirement inside API 570, API 571, API 574 or API 578 and apply it to a scenario rather than recall a definition. Candidates with field inspection experience and thorough familiarity with the documents generally find it more manageable.
What should I study, and in what order?
Start with API 570 itself to build the framework, then add API 571 for damage mechanisms, API 574 for inspection practices and API 578 for code comparisons. Layer in ASME B31.3 and the welding code requirements referenced by the exam. Finish with practice questions and calculation drills on retirement thickness and inspection intervals.
Can I bring the code books into the exam?
Reference availability during the exam is an API policy and has changed over time. Do not rely on assumptions or on what past candidates describe. Confirm the current permitted-materials rule with API when you register, and prepare to work from memory if references are not allowed.
What if I fail - can I retake it?
API sets its own retake policy, including any waiting period and any limit on attempts. Those terms are not reproduced here because they are revised periodically. Review the retake and rescheduling rules on API's ICP pages before you sit the exam so you know your options in advance.
How long is the certification valid?
Recertification is required to keep the credential active, and API defines the cycle and renewal requirements. Confirm the current validity period and recertification process on the API ICP page for API 570, and calendar your renewal date as soon as you are certified.
What are the most common reasons candidates fall short?
Three recurring problems: studying only API 570 and skipping the companion documents where many questions originate; memorizing tables without understanding how to apply inspection intervals and retirement thickness calculations; and never practicing under time pressure with scenario-style questions. Broad, document-by-document reading plus timed practice addresses all three.
How should I use this page's practice questions?
Treat them as a diagnostic, not a substitute for the source documents. Work each item, then go back to the cited code paragraph and read the surrounding text. Rotate across all five content areas rather than drilling your strongest one, and revisit missed items after a delay to confirm retention.
