API RP 571 - Damage Mechanisms Affecting Fixed Equipment in the Refining Industry

Explore this topic

API RP 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry, is a recommended practice developed and published by the American Petroleum Institute (API) that provides an in-depth look at over 60 different damage mechanisms that can occur to process equipment in refineries. This recommended practice was originally published in 2003, and the latest 3rd Edition was released in March of 2020. It includes a general description of the damage mechanism, susceptible materials of construction, critical factors, inspection method selection guidelines, and control factors. This RP is intended to supplement API RP 580, API RP 581, and API RP 579, and is nearly 400 pages long.

API RP 571 contains sections for different types of damage mechanisms. Each mechanism is given a write up that consists of a description of the mechanism, a list of materials that are susceptible to that mechanism, guidelines for inspecting for that mechanism, and measures that can be taken to prevent or mitigate that particular mechanism.

Examples of the types of damage mechanisms covered by API RP 571 include, but are not limited to:
