文摘

Stress analysis was performed following the ASME design-by-analysis. Storage tanks axisymmetric and solid finite element models were developed. Smooth bar design fatigue curve was obtained to perform the fatigue evaluation. Clean out juncture is critical for the fatigue life of API 12F tanks. Smaller diameters allow less pressure cycles than tanks with larger diameters.
