API RP 970 - Corrosion Control Documents

Explore this topic

API RP 970, Corrosion Control Documents, is a recommended practice developed and published by the American Petroleum Institute (API) to provide users with the basic elements for developing, implementing and maintaining a Corrosion Control Document (CCD) for a refinery, and at the owner's discretion, may be applied at petrochemical and chemical process facilities. The current and 1st Edition of this RP was published in December of 2017.

A CCD is a document or other repository or system that contains all the necessary information to understand material damage susceptibility issues in a specific type of operating process unit at a facility. CCDs are a valuable addition to an effective Mechanical Integrity program. They help to identify the damage mechanism susceptibilities of pressure containing piping and equipment, factors that influence damage mechanism susceptibilities, and recommended actions to mitigate the risk of loss of containment or unplanned outages.

API RP 970 serves as the basis for tracking CCD development, implementation, and maintenance to maintain consistency and to integrate the CCD work process with other plant integrity programs, such as Management of Change (MOC), Process Hazards Analysis (PHA), and Reliability Centered Maintenance (RCM).

Some of these programs have significant overlap with the development of CCDs, including Risk-Based Inspection studies (see API RP 580 and RP 581), Integrity Operating Windows (see API RP 584), in-house unit corrosion reviews, circuitization/systemization programs, and similar types of corrosion studies. Development of CCDs can serve as a useful starting point for establishing these programs if they have not been undertaken.
