What you'll learn

  • Calculate corrosion rate, remaining life, required thickness and retirement thickness, and MAWP from measured thickness
  • Navigate API 570 — scope, piping classes, exclusions, and the inspector, owner-user and engineer responsibilities
  • Apply ASME B31.3 pressure design — allowable stress, mill tolerance, ratings and branch reinforcement
  • Identify piping damage mechanisms and set condition monitoring locations for common services
  • Set inspection intervals by piping class, including injection points, deadlegs and CUI circuits
  • 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
  • Find the controlling clause in API 570 and B31.3 quickly, and follow a structured study plan into the exam

Course content

7 sections • 24 lectures • 4h 31m total length

  • Scope, Applicability & Piping Classes10:06

    What API 570 covers for in-service metallic piping, how it relates to the construction code, and how piping classes based on consequence of failure set inspection intervals.

  • Responsibilities & Certification10:44

    The duties of the owner-user, authorised inspector and repair organisation under API 570, and the certification route for API 570 piping inspectors.

  • Inspection Intervals by Class10:32

    How to set inspection intervals for Class 1, 2 and 3 piping, including thickness and external visual limits, the half-life rule and special circuits.

  • Reference Codes & Standards Map10:35

    How API 570 links to supporting standards for design, inspection, welding, NDE, damage mechanisms and fitness for service, including B31.3, API 574, API 571 and API 579.

  • Section 1 Quiz: API 570: The API 570 Code & Inspector's Role

Requirements

  • No prior piping inspection experience is required — the code context is built from the ground up
  • Any engineering or technical background is enough to follow the course
  • Access to API 570 and ASME B31.3 is recommended for the exam itself, but every principle is explained in the course
  • No software needed — bring a calculator and a willingness to work the numbers

Description

This course contains the use of artificial intelligence.


Most API 570 candidates do not fail for lack of knowledge. They fail because they cannot find the clause and work the calculation fast enough.


The exam tests applied code knowledge across API 570, ASME B31.3 and the API and ASME documents they reference. You need to find the right clause, apply it, and move on.


This course trains that skill, and covers the piping knowledge a working inspector uses on the plant.


WHAT YOU WILL LEARN TO DO

By the end of this course you will be able to:

  • Navigate API 570 scope, piping classes and the responsibilities of the inspector and owner-user
  • Apply B31.3 pressure design, component ratings and branch reinforcement
  • Identify piping damage mechanisms, including injection points, deadlegs, soil-to-air and CUI
  • Set CMLs and an inspection interval for each piping class
  • Calculate corrosion rate, remaining life, required thickness and MAWP
  • Select inspection and NDE methods under API 574 and ASME V
  • Use risk-based inspection to prioritise piping circuits
  • Apply the rules for repairs, alterations and rerating
  • Work exam-style calculations quickly under time pressure


HOW THE COURSE IS TAUGHT

  • Built around how the exam is set: find the clause, apply it, move on
  • Worked calculations shown step by step
  • Code navigation drills for API 570 and B31.3
  • A full exam preparation section with a mock exam walkthrough and study plan
  • No padding — six focused sections you can work through in a week of evenings


WHAT IS COVERED

  • API 570 scope, piping classes, inspector responsibilities and certification
  • Inspection intervals by class and the reference code map
  • B31.3 pressure design, components, ratings, flanges and branch reinforcement
  • Materials, toughness and MDMT
  • Internal and external corrosion, injection points, deadlegs and soil-to-air interfaces
  • Erosion, FAC and vibration, and setting CMLs and TMLs
  • Inspection techniques (API 574) and NDE for piping (ASME V)
  • Thickness evaluation, retirement limits and risk-based inspection
  • Repair versus alteration, temporary repairs, welded repairs, testing and rerating
  • Exam structure, worked calculations, code navigation drills and a mock exam


120 PRACTICE QUESTIONS

Every section ends with a quiz built around realistic scenarios, so you test your understanding as you go and reinforce what you have learned. Each answer comes with a short explanation.


Enrol today and walk into the exam knowing where to look and how to calculate.

Who this course is for:
