API 579 Part 4 and Part 5 – General and Local Metal Loss
Metal loss is one of the most common flaws encountered in service. INSPECT addresses metal loss with its rigorous API 579-1 general and local metal loss assessments and detailed reports. INSPECT’s 3D models take the guess work out of verifying that the metal loss has been correctly entered. Since other flaws such as pitting are often present within metal loss regions, INSPECT detects pitting overlaid onto the metal loss and factors this in accordingly. INSPECT covers:
Level 1 and 2 assessments for both Part 4 and Part 5.
Local metal loss assessments for nozzles. These Level 2 assessments follow the rules of API 579, Part 4 (184.108.40.206). INSPECT’s 3D modeling capabilities simplify this process providing concise nozzle assessments quickly.
Supplemental loads due to wind, seismic, weight, liquid contents, lateral forces and vertical loads. These are automatically considered for Part 4, Level 2 assessments.
Integration with Olympus Data loggers (read/write capabilities) for enhanced productivity.
Part 5 – Groove-like Flaws
API 579 Part 5 groove-like flaw assessments can be utilized in INSPECT to perform “What if” scenarios for possible remedies to flawed areas. For example, would the flaw pass assessment if the crack or metal loss was ground into a groove-like flaw? Groove-like flaws may be combined with pitting damage (Part 6) as well.
