New From the American Petroleum Institute (API) - API RP 571

This article appears in the March/April 2004 issue of Inspectioneering Journal.

API Recommended Practice 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry

The API has just released the First Edition. This document provides background information on damage that can occur to equipment in the refining process. It is intended to supplement Risk-Based Inspection (RP 580 and Publ. 581) and Fitness-for-Service (RP 579) technologies developed in recent years by API to manage existing refining equipment integrity and the API pressure vessel and piping inspection codes. It is also an excellent reference for inspection, operations, and maintenance personnel.

API RP 571 covers over 60 damage mechanisms. Each write-up consists of a general description of the damage, susceptible materials of construction, critical factors, inspection method selection guidelines, and control measures. Wherever possible, pictures are included and references are provided for each mechanism. In addition, generic process flow diagrams have been included that contain a summary of the major damage mechanism expected for typical refinery process units.

API also offers a NEW course on damage mechanisms and NDE that will use RP 571 document as a reference. For more information on API RP 571 or the 571 course visit the web site and click on the "Standards and Technical Publications" link and/or the "Industry Training, Education and Meetings" link.
