Fitness-For-Service (FFS) Analysis
Comprehensive structural integrity evaluations, remaining life predictions, and damage mechanism modeling according to API 579-1 / ASME FFS-1 standards for high-pressure boilers, vessels, and industrial piping networks.
Quantitative Fitness-For-Service Assessments
Saudi Boilers delivers rigorous API 579-1 / ASME FFS-1 engineering evaluations to determine the structural suitability of aging, damaged, or degraded pressure equipment. We help plant operators avoid unnecessary capital replacements by safely extending asset operating lifespans.
Metal Loss & Wall Thinning
Quantify generalized wall loss, localized corrosion pockets, and erosion profiles against maximum allowable working pressure (MAWP).
Crack & Fracture Mechanics
Perform crack-like flaw calculations, stress intensity factor evaluations, and brittle fracture prevention audits.
LEVEL 1 & 2 SCREENING
1. Level 1 & Level 2 Screening Calculations
Rapid screening methods using empirical formulas, thickness grids, and conservative design equations. Provides quick, cost-effective verification of component safety margins without heavy computing overhead.
- Minimum Required Thickness (t-min) Verification
- API 579 Part 4 & 5 Metal Loss Screening Curves
- MAWP Derating & Re-rate Calculation Reports
LEVEL 3 FEA & FRACTURE
2. Level 3 Advanced Finite Element Analysis
When equipment fails Level 1/2 screening, our Level 3 FEA specialists perform non-linear stress analysis, elastic-plastic collapse assessments, and 3D crack propagation modeling to unlock hidden structural reserves.
- Elastic-Plastic Protection Against Plastic Collapse
- 3D Crack Failure Assessment Diagrams (FAD)
- Transient Thermal-Creep Interaction Modeling
Comprehensive Degradation Diagnostics
General & Local Metal Loss
API 579 Parts 4 & 5 assessments for internal corrosion, erosion-corrosion, and external atmospheric wall loss.
Pitting Corrosion & Blisters
API 579 Parts 6 & 7 evaluations for localized pitting arrays, hydrogen blistering, and HIC/SOHIC damage.
Dents, Gouges & Distortion
API 579 Parts 12 & 13 assessments for mechanical dents, gouges, shell out-of-roundness, and weld misalignment.
Creep & Thermal Fire Damage
API 579 Parts 10 & 11 assessments for high-temperature creep accumulation, microstructural degradation, and fire damage.
