This is a for the topic: “API RP 586: Technical Report on Pipe Flange Leakage” (formally API Recommended Practice 586 ).
Used extensively for detecting and sizing surface-breaking cracks through paint and scale, eliminating intensive surface preparation.
This represents the next step in API's goal to create a comprehensive guide for NDT methods across various damage mechanisms. api rp 586 pdf

Highly effective for surface and near-surface cracks without stripping protective coatings.
Carbonate SCC, Amine SCC, and Chloride SCC. If you need a legitimate , here are
A: No, it is a Recommended Practice . This means its use is voluntary. However, an authority having jurisdiction or an employer can incorporate it by reference into their own mandatory requirements.
Addresses common issues like general thinning, localized corrosion, pitting, and environmental cracking (such as H2S-related cracking). Maintenance & Reliability:
Common challenges include poorly documented past repairs, CP interference from nearby structures or DC-powered equipment, and inconsistent inspection records. Integrating RP 586 recommendations into an asset integrity management program, and keeping thorough records, reduces these gaps and aids regulatory compliance.
: Provides guidance on selecting NDE methods (e.g., eddy current, magnetic flux leakage, ultrasonic) for inspecting shell and tube heat exchangers.
