API RP 586 is structured to be updated periodically, with specific sections focusing on particular damage mechanisms or equipment types.
Because this is a multi-part standard, what you need depends on the specific equipment or damage you are analyzing. As of recent drafts, the standard is organized as follows: API RP 586-1: Heat Exchanger Tubing Inspection
: Dictates Multi-Frequency Eddy Current Testing (ECT).
It covers non-destructive evaluation (NDE) techniques to detect and measure damage at crevice points where piping rests on supports. api rp 586 pdf

| Class | Maximum Leak Rate | Typical Application | |-------|------------------|---------------------| | Class I | ≤ 10⁻² mg/sec/mm | General refinery, low risk | | Class II | ≤ 10⁻³ mg/sec/mm | Process with minor toxicity | | Class III | ≤ 10⁻⁴ mg/sec/mm | Hydrogen service, H₂S | | Class IV | ≤ 10⁻⁵ mg/sec/mm | Very low emissions (TA Luft) |
API RP 586: NDT Methods for Equipment Damage Mechanisms API RP 586 API RP 586 is structured to be updated
The , titled "NDE Methods for Equipment Damage Mechanisms," is a newly developed recommended practice by the American Petroleum Institute. It provides comprehensive guidance on selecting and applying Non-Destructive Evaluation (NDE) techniques to detect specific damage mechanisms in refinery and chemical equipment.
: Provides guidance on selecting NDE methods (e.g., eddy current, magnetic flux leakage, ultrasonic) for inspecting shell and tube heat exchangers.
Published by the , RP 586 focuses specifically on liquid product sampling. It complements other API standards (like MPMS Chapter 8.2 for manual sampling and MPMS Chapter 8.3 for automatic sampling) but provides more practical, application-oriented guidance for refineries and large terminals. It provides comprehensive guidance on selecting and applying
If you are currently implementing this standard at your facility,For example, I can provide more details on:
Detailed guidance on selecting the proper NDE method (e.g., PAUT, TFM, Eddy Current) for a given damage mechanism.
As the energy sector moves toward more advanced, proactive mechanical integrity management, the continues to update its guidelines for inspecting critical infrastructure. One of the most significant emerging documents is API RP 586 , titled "NDT Methods for Equipment Damage Mechanisms," which focuses on selecting the best Non-Destructive Testing (NDT) tools to detect specific flaws in pressure vessels, piping, and heat exchangers.
