Pitting Corrosion (PC)
API 579-1/ASME FFS-1 Part 6
Evaluation of pitting damage in pressure vessel components
Unified Assessment Wizard
Choose your geometry and assessment level interactively in a single guided flow. The wizard adapts to the geometry you pick: cylinders expose all four Level 2 variants, while spherical shells support Level 1 and Level 2 standard.
Cylinder
Cylindrical pressure vessels and piping. Separate longitudinal and circumferential joint efficiencies.
- Level 1 screening (pit charts)
- Level 2: Standard (widespread / localized)
- Level 2: Confined in LTA
- Level 2: LTA in widespread pitting
- Level 2: With supplemental loads
Spherical Shell
Spherical vessels and hemispherical heads. Single (isotropic) joint efficiency.
- Level 1 screening (pit charts)
- Level 2: Standard (widespread / localized)
