Process Plant Piping Maintenance & Repair

I. Introduction

The structural integrity of piping systems must be maintained after they have been placed into service so that they will provide safe, reliable, long-term operation. Therefore, existing piping systems require periodic inspection to determine their current condition and permit evaluation of their structural integrity to permit future operation. Should unacceptable deterioration or flaws be identified, pipe repairs may be required. Existing piping systems might also require alterations or rerating to accommodate new operational needs (or to

accommodate deterioration that cannot or will not be repaired).

Process plants must adopt and follow established procedures for the inspection, repair, alteration, and rerating of piping systems after they have been placed into service. API 570, “Piping Inspection Code – Inspection, Repair, Alteration, and Rerating of In-Service Piping Systems,” provides the basic procedures to be followed by process plants. This course is based on API 570.

Scope of API 570

API 570 was developed for the petroleum refining and chemical process industries. But since most of its requirements have broad applicability, it may be used for any piping system. It must be used by organizations that maintain or have access to an authorized inspection agency, a repair organization, and technically qualified piping engineers, inspectors, and examiners (as defined in API 570).
