In-Service Inspection and Repair Codes and Standards: How Do They All Work Together?

摘要

After pressure equipment (aka fixed or static equipment) is designed, fabricated, and constructed to new construction codes and standards (C/S), it is placed in-service, at which time the API In-service Inspection (ISI) C/S and ASME Post-Construction C/S begin to govern. Within the API Standards Organization, the Subcommittee on Inspection (SCI) produces and maintains most of the ISI standards that govern in the refining and chemical process industry. Also within the API, the Corrosion and Materials Subcommittee (CMSC) produced many recommended practices that are referenced in the ISI C/S. Within the ASME, the Post Construction Committee (PCC) produces and maintains most of the post construction (means the same as ISI) standards that govern equipment after it has been placed in-service. This article shows how many of those ISI C/S are intended to work together to maintain the safety and reliability of in-service pressure equipment and piping. An important note for each reader of this article is to be cognizant of using the latest edition of each of the referenced ISI C/S. Both the API and ASME use the rigorous, standardized consensus building process outlined by the American National Standards Institute (ANSI) for formulating and publishing their respective C/S. Because of active ISI standardization programs within both societies, the latest editions of the referenced ISI C/S have some important revisions and additions that make each of the referenced ISI C/S better and more useful for the owner-user. So it's very important that each reader have access to the latest edition of each of the referenced ISI C/S at the end of this article.
