If you answered yes to these questions, or if pitting corrosion due to other factors is occurring in your plant, an API FFS pitting aoi may provide an alternative to costly repairs. The purpose of the document is to provide a consensus of methods to quantitatively evaluate commonly observed damage to in-service pressure equipment.

Pitting is defined by API as localized regions of metal loss characterized by a pit diameter on the order of the plate thickness or less. Forside Nettbutikk Produktkatalogen Produktpresentasjon. These rules typically result in one component with a thickness that is dependent upon another component. The role of the inspector in gathering data and evaluating that data will be discussed as will be the role of the technologist and engineer in appraising the data and employing it in engineering calculations.
This course has already completed. His experience includes Fitness-for-service assessments and design support of pressurized equipment including elastic-plastic Finite Element Analysis, transient heat transfer analysis, creep, high-and low cycle fatigue, fracture mechanics, fluid surge and piping flexibility analysis. Becht Nuclear 36 post s. Did a unit upset result in internal pitting on the bottom head of the reactor? General Interest 4 post s.
This standard has been used to avoid costly and unnecessary unplanned outages, while maintaining safe and reliable equipment.

The procedures are not intended to provide a definitive guideline for every possible situation that may be encountered.
These components have a code design procedure to determine an acceptable configuration. A limited discussion will be presented on advanced methods of assessment. Available Positions Apply On-line. This Standard has broad application since the assessment procedures are based on allowable stress methods and plastic collapse loads for non-crack-like flaws, and the Failure Assessment Diagram FAD Approach for crack-like flaws.
Article 4, API 579-1: Fitness-For-Service (FFS) – Pitting Assessment
If the depth of all the pits is less than the specified corrosion allowance, then a pitting assessment is not required. However, flexibility is provided to the user in the form of an ai assessment level to handle uncommon situations that may require a more detailed analysis. In addition to the many clarifications, updated references to codes and standards, several changes and additions have been made to improve the standard in its most recent update. Litigation Support 3 post s.
GML Level 2 assessments are permitted only if certain conditions are satisfied. Another example is the previous Annex B1, which contained the procedures for demonstrating protection against various failure modes using stress analysis, which is now under Part 2 in Annex 2D.

The information in Annex H, along with knowledge of the differences in design codes, should enable the user to factor, scale, or adjust the acceptance limits of this Standard such that equivalent FFS inservice margins can be attained for equipment not constructed to these codes.
