Level 1 pitting assessments are permitted only if certain conditions are satisfied. The purpose of the document is to provide a consensus of methods to quantitatively evaluate commonly observed damage to in-service pressure equipment. A limited discussion will be presented on advanced methods of assessment. Sign up for eNewsletter. Available Positions Apply On-line.

Below is a summary of the assessment process. Note that for a Level 1 assessment, the future pitting damage FCA is assumed to be zero, e. This approach provides an entry point into the ASME or API codes refer also to Annex 579- wherein the pressure-containing component is reconciled or generally made equivalent to the design bases assumed for this Standard.

In a Level 1 assessment, surface damage, quantified by the pitted 579–1 and pit depth, is compared to standard pit charts to determine acceptability.

Pressure Vessels 18 post s. However, if the pit depth exceeds the corrosion allowance, then a pitting assessment should be considered. Systems 2 post s. These are components that do not have a design equation that specifically relate pressure or liquid fill height, and other loads, to a required wall thickness. However, flexibility is provided to the user in the form of an advanced assessment level to handle uncommon situations that may require a more detailed analysis. Other examples of Type B Components include the reinforcement zone of conical transitions, branch connections, and flanges.

Phone please use format: 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.

If the depth of all the pits is aoi than the specified corrosion allowance, then a pitting assessment is not required. 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.
