API 570: Piping Inspector Exam Preparation
ASME B31.3, Thickness Evaluation, RBI & Repairs — Pass the API 570 Piping Inspector Exam
Last updated 7/2026
English
What you'll learn
- Navigate API 570 - scope, piping classes, exclusions, and the inspector, owner-user and engineer responsibilities
- Set piping inspection intervals by class, including injection points, deadlegs and corrosion-under-insulation circuits
- Apply ASME B31.3 design principles - pressure-design thickness, allowable stress, mill tolerance, ratings and branch reinforcement
- Identify piping damage mechanisms and set condition monitoring locations across circuits of common metallurgy and service
- Calculate corrosion rate, remaining life, required thickness and retirement thickness, and compute MAWP from measured thickness
- Select NDE methods for piping - profile radiography, UT scanning and guided-wave screening under ASME V
- Apply risk-based inspection concepts (API 580/581) to prioritise piping circuits
- Apply the repair and alteration rules - clamps, composite wraps, welded sleeves and rerating
- Work exam-style piping calculations cleanly under time pressure
- Navigate API 570 and B31.3 quickly to the controlling clause, with a structured study plan into the exam

Course content
6 sections • 24 lectures • 4h 33m total length
Requirements
- A background in mechanical, inspection, materials or engineering discipline - the course is built for professionals
- Some exposure to process piping or plant inspection is helpful but not essential - the course builds the code context from the ground up
- Access to API 570 and ASME B31.3 is recommended for the exam itself, though the principles are explained independently
- No software is required - this is an applied, code-and-calculation course aimed at certification and real inspection practice
Description
This course contains the use of artificial intelligence.
Most API 570 candidates fail for the same reason. They study the wrong way.
They memorise definitions. They read the code cover to cover. And they run out of time in the exam because they've never trained the skill that actually decides the result — navigating the code fast and working calculations cleanly under pressure.
This course fixes that.
What the exam actually tests:
API 570 is not a recall test. It tests applied code knowledge across API 570, ASME B31.3, API 574, 577, 578, 571, 579, and ASME V. You need to find the right clause, apply it correctly, and move on — all within tight time constraints.
This course trains exactly that.
What's inside:
Six structured sections covering everything on the exam blueprint:
The code framework and the inspector's role
B31.3 pressure design principles
Damage mechanisms in process piping
Inspection planning, thickness evaluation, and corrosion rate calculations
Repairs, alterations, and rerating
A dedicated exam preparation section with worked calculations and a full mock exam walkthrough
The piping traps that catch candidates out:
Injection points. Deadlegs. Soil-to-air interfaces. Corrosion under insulation. Erosion at bends and control valves. You'll learn where damage concentrates, how to set condition monitoring locations, how to calculate remaining life and required thickness, and how API 580/581 risk-based inspection is used to prioritise circuits.
Built by a practising engineer:
This content is developed by a Chartered Engineer working on safety-critical process infrastructure — not a training company recycling old material. It is technically correct, current, and built around how the exam is actually marked.
Who this is for:
Engineers and inspectors preparing to sit the API 570 certification exam
Working piping inspectors who want sharper code application on the plant
Anyone who has already attempted API 570 and wants to pass it this time
If you inspect process piping — or you're preparing to certify — this course is built to get you to a pass and make you better in the field.
Who this course is for:
- Engineers and technicians preparing to sit the API 570 Piping Inspector certification examination
- Working piping inspectors who want their applied B31.3 and API 570 knowledge sharpened
- Mechanical and integrity engineers who specify, review or sign off piping inspection programmes
- Reliability and maintenance engineers responsible for piping integrity and corrosion management
- Inspectors already holding API 510 who are adding the piping certification to their credentials
