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 nearly 70 different damage mechanisms that can occur to process equipment in refineries. According to the third edition of this recommended practice, its purpose is “to describe the wide variety of service-induced damage and deterioration mechanisms, including corrosion and other types of metallurgical damage, that are most likely to affect the condition of the materials of construction commonly used in refinery equipment.”

API RP 571 was originally published in 2003, and the third edition was released in March of 2020. This RP is intended to supplement API RP 580, API RP 581, and API RP 579, and is nearly 400 pages long.

Each of the damage mechanisms found in API RP 571 is given a write up that consists of a description of the mechanism, a list of materials that are susceptible to that mechanism, critical factors that affect the mechanism (i.e., rate of damage), affected equipment and/or units where the damage mechanism commonly occurs, appearance or morphology of the damage, and measures that can be taken to to prevent or mitigate that particular mechanism. In many cases, pictures or graphics are included to provide additional valuable context to the reader.

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

API 571 Corrosion and Materials Certification

API offers a 571 certification through their Individual Certification Program (ICP). The body of knowledge and exam questions for this certification are derived from the API RP 571 document. As of November, 2021, there are over 1,800 active API 571 certified individuals globally [1].

Individuals who hold current API 510, 570, or 653 certifications automatically qualify to take the certification exam. Otherwise, qualification is based on a combination of education level and industry experience.
