API 579-1/ASME FFS-1 Part 5

Isolated areas of metal loss including pits and grooves

Unified Assessment Wizard

Choose your geometry and assessment level interactively in a single guided flow. Both cylinders and spherical shells support Level 1 (R_t screening) and Level 2 (RSF from thickness profile).

Launch Assessment Wizard

Cylinder

Cylindrical pressure vessels and piping. Separate longitudinal & circumferential joint efficiencies.

Level 2 (RSF from thickness profile)

Start with Cylinder

Spherical Shell

Spherical vessels and hemispherical heads. Single isotropic joint efficiency.

Level 1 screening
