Integrity Field Guide: Reading the Damage in Plant Equipment

Editorial interest 84/100 Selection signal · not a rating of the site

A free engineering study guide explains API 571 damage mechanisms, API 579 fitness-for-service, and the inspection methods used to identify failing equipment.

Landing page captured for the 2026-08-24 issue.

Field notes

The guide separates two kinds of engineering judgment: API 571 identifies the mechanisms attacking metal, while API 579-1/ASME FFS-1 evaluates whether equipment outside its original rules may still operate. Its teaching path combines wall cross-sections, inspection-method guidance, practice questions, and demonstrations based on fixed cases. Readers can vary numbers to observe equation behavior, but cannot enter plant data or obtain a real equipment verdict, a boundary the site states is deliberate.
