heat exchanger designs. It outlines the principles, capabilities, and limitations of NDT methods like Eddy Current Testing Magnetic Flux Leakage Ultrasonic Testing for ferrous and non-ferrous tubing.

Section 2: Inspection for High Temperature Hydrogen Attack (HTHA) Replacing and expanding on the old Annex E of API RP 941 api rp 586 pdf

The document is organized into specific parts based on the type of damage mechanism or equipment being inspected: eballotprodstorage.blob.core.windows.net Key Sections of API RP 586 Section 1: Heat Exchanger Tubing Inspection This section covers common Shell and Tube Air-Cooled heat exchanger designs

, this section provides optimized techniques for detecting early-stage HTHA. It highlights volumetric Ultrasonic Testing (UT) methods such as: Time of Flight Diffraction (ToFD) for rapid screening. Phased Array Ultrasonic Testing (PAUT) Full Matrix Capture (FMC) for higher-confidence sizing and characterization. Section 3: NDE for Contact Point Corrosion (CPC) eballotprodstorage

API Recommended Practice 586 ( API RP 586 ), titled "NDE Methods for Equipment Damage Mechanisms," is a newer recommended practice that provides detailed guidance on selecting and using Non-Destructive Evaluation (NDE) techniques for in-service equipment. eballotprodstorage.blob.core.windows.net

: The improved inspection data from these methods directly supports more accurate FFS assessments under standards like API 579-1/ASME FFS-1 eballotprodstorage.blob.core.windows.net or a specific technical summary of one of these sections? Draft - For Committee Review
