: Offers guidance on wall thickness measurement principles and limitations to support fitness-for-service (FFS) assessments. Why It Matters

As industrial equipment continues to age and operate under increasingly harsh conditions, the precision offered by API RP 586 becomes indispensable. By shifting the focus from general "checks" to mechanism-specific evaluations, the standard significantly reduces the risk of catastrophic failure and enhances the overall safety and longevity of critical infrastructure.

This section defines the boundaries of the recommended practice. It outlines how RP 586 applies to pressure vessels, piping, storage tanks, and heat exchangers. It also connects the document to other vital standards, such as API 510 (Pressure Vessel Inspection), API 570 (Piping Inspection), and API 580/581 (Risk-Based Inspection). 2. Damage Mechanism Mapping

The primary goal of API RP 586 is to shift the maintenance strategy from "Run-to-Failure" or "Time-Based" to "Condition-Based" or "Risk-Based."
