Becht Engineering has extensive a;i and expertise in the conduct of Fitness-For-Service. If you answered yes to these questions, or if pitting corrosion due to other factors is occurring in your plant, an API FFS pitting assessment may provide an alternative to costly repairs. Did a unit upset result in internal pitting on the bottom head of the reactor?

A limited discussion will be presented on advanced methods of assessment.

Reliability Improvement 29 post s. Becht Nuclear 36 post s. 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 aip analysis.

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. However, the user is cautioned to also consider the effects of fabrication and inspection requirements on the design basis e.

However, if the pit depth exceeds the corrosion allowance, then a pitting assessment should be considered. This standard has been used to avoid costly and unnecessary unplanned outages, while maintaining safe and reliable equipment.

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.

In a Level 1 assessment, surface damage, quantified by the pitted area and pit depth, is compared to standard pit charts to determine acceptability. Other examples of Type B Components include the reinforcement zone of conical transitions, branch connections, and flanges.

Substantive Changes to the Edition Fitness for Service. Widely scattered pitting is pitting that occurs over a significant region of the component. Becht Software 4 post s.

Details of the process, as well as spi nomenclature, can be found in API Part 6. These are components that have a design equation that specifically relate pressure or liquid fill height, and other loads, to a required wall thickness e.

Since it was first issued by API inthis Fitness-For-Service standard has been used worldwide as a means of evaluating whether pressure equipment was fit for continued service, and in many cases, for how long. 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 Ali Assessment Diagram FAD Approach for crack-like flaws.

Piping 29 post s. 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.

In addition, evaluation techniques are provided for condition assessment of equipment including resistance to brittle fracture, long-term creep damage, and fire damage. These are components that do not have a design equation that specifically relate pressure or liquid fill height, 5579-1 other loads, to a required wall thickness.

Below is a summary of the assessment process.
