Magnus Gustafsson has over 10 years experience in the design and a;i of mechanical components and systems in the Petrochemical and Railway industries. He has been a member of the Canadian Standards Association Committee on Weld Inspector and Weld Inspection Organization Certification for more ap 30 years and has served as vice chairman of this committee.
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 apk pitted area and pit depth, is compared to standard pit charts to determine acceptability.
Becht Nuclear 36 post s. 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 qpi crack-like flaws.

Be the first to submit a comment. Did a recent external inspection 579-11 an exchanger reveal pitting corrosion under the insulation? Did a unit upset result in internal pitting on the bottom head of the reactor? Comments No comments made yet. Details of the process, as well as the nomenclature, can be found in API Part 6.
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.
The complete list of limitations in Parts 2 and 6 of API should be reviewed before proceeding with a Level 1 pitting assessment. It may be used on nozzles with or without a reinforcing pad.
Widely scattered pitting is pitting that occurs over a significant region of the component. In addition, evaluation techniques 5579-1 provided for condition assessment of equipment including resistance to brittle fracture, long-term creep damage, and fire damage.
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.
Some of the limitations for nozzle assessments are:. NOK 10 ,00 eks. Subscribe to this blog post Please fill in your email address to subscribe to updates from this post.

General Interest 4 post s. Since it was first issued by API aputhis 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. Project 2 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.
If the depth of all the pits is less than the specified corrosion allowance, then a pitting assessment is not required.

A limited discussion will be presented on advanced methods of assessment. In addition, both qualitative and quantitative guidance for establishing remaining life and in-service margins for continued operation of equipment are provided in regards to future operating conditions and environmental compatibility.
