(Recommended Practice 586) provides standardized methodology to evaluate leakage rates from bolted pipe flanges. Unlike traditional flange design (ASME BPVC Section VIII) which focuses on mechanical strength, API RP 86 addresses emissions control — critical for refinery, petrochemical, and natural gas facilities subject to fugitive emission regulations (e.g., EPA Method 21, LDAR programs).
API Recommended Practice (RP) 586 is a critical document for the refining and petrochemical industries, specifically designed to consolidate Non-Destructive Examination (NDE) methodologies for identifying and assessing damage mechanisms in fixed equipment. api rp 586 pdf
These advanced algorithms provide near-ideal focusing throughout the material thickness, allowing for precise sizing of challenging damage. Integration with Existing Standards The Ultimate Guide to API RP 586: How
