API RP 586 represents the evolution of asset integrity management from a reactive discipline to a predictive and strategic function. By providing a robust framework for assessing both the probability and consequence of failure, it empowers operators to make data-driven decisions regarding inspection planning. While the implementation requires significant commitment regarding data management and personnel training, the resulting optimization of safety and cost efficiency makes API RP 586 an indispensable standard for the modern energy industry.

API RP 586, "NDE Methods for Equipment Damage Mechanisms," provides technical guidance on selecting and applying non-destructive evaluation (NDE) techniques to identify specific damage in industrial fixed equipment. The document focuses on specialized methods for heat exchanger tubing, high-temperature hydrogen attack (HTHA), and contact point corrosion (CPC) to support safety and fitness-for-service assessments. For technical insights into contact point corrosion detection, review API RP-586 Part 3. Draft - For Committee Review
Before taking a grab sample, the system must be flushed sufficiently (often 3-5 system volumes) to ensure the sample represents the current pipeline contents, not the stagnant volume from the previous hour. api rp 586 pdf
To understand the specific role of RP 586, it is necessary to contextualize it within the API RBI document hierarchy. Users often conflate these documents, but they serve distinct purposes:
Note: In many industry circles, the practical implementation details are often discussed in tandem with the upcoming API RP 581 (Quantitative Risk-Based Inspection), which provides specific calculation methodologies. However, API RP 586 serves as the comprehensive recommended practice for applying RBI technology consistently.
API RP 586 is a recommended practice published by the American Petroleum Institute (API). Its full title is: "API Recommended Practice 586: Technical Report on Material Traceability and Identification for Subsea and High-Pressure High-Temperature (HPHT) Equipment."
It is important to note a frequent source of confusion: API RP 586 is technically identical to API 17TR2 (Technical Report 2). In 2015, the API renumbered several subsea documents. What was once API 17TR2 is now API RP 586. Therefore, when you search for an "API RP 586 PDF," you are also searching for the latest edition of the 17TR2 guidelines. API RP 586 represents the evolution of asset
Compare your existing procurement and inspection procedures against the "shall" statements in API RP 586. Create a compliance matrix.
While RBI can be performed manually on a small scale, API RP 586 implementation typically requires specialized software. These tools automate complex calculations for damage rates and dispersion modeling for consequence analysis.
The POF assessment is a quantitative or qualitative evaluation of the likelihood that a piece of equipment will fail within a specific time frame. API RP 586 guides the analysis of:
