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

Last update: Jan 16, 2017

API RP 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry, Second Edition, is a recommended practice developed and published by the American Petroleum Institute (API). The first edition was published in December of 2003, and an updated second edition was released in April of 2011. This RP provides an in-depth look at over 60 different damage mechanisms that can occur to process equipment in refineries. 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 257 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:

Seasoned and knowledgeable inspectors are becoming harder and harder to keep. But using some of the industry documents in a smart way, inspectors with less experience can perform like an inspector with many more years of experience and even develop a great materials specialty with practice.

Experienced material specialists are in short supply and high demand these days. So if you are lucky enough to have one at your disposal, how can you squeeze the most out of that opportunity?

Auto-refrigeration can impose low temperatures onto process vessels and piping causing them to be at risk of brittle fracture, the sudden break-before leak phenomena that can result in catastrophic rupture of the equipment.

New API Inspector Certification Endorsement Program (ICEP)

At PinnacleAIS, we often get requests for a Senior API Inspector. But what does that mean exactly? What qualifications are required? Is there a test or a certification that provides the end user with assurance they are getting a higher caliber inspector or inspection service? Often there are different ideas of what comprises a "Senior" Inspector.

High temperature oxidation is not a real common type of failure in our industry, but it can and does happen when temperatures exceed design maximums. All metals oxidize, even at room temperature, and in many cases that slow oxidation process actually protects the metal from rapid oxidation.
