Interacting Pipeline Defect Modules

Calculate DNVGL RP F101 allowable pressure for interacting corrosion defects with internal pressure load only.

Single defects which are closer together than the minimum defect spacing should be treated as interacting defects. The allowable pressure can be calculated using either the calibrated safety factor (CSF) in section 3, or allowable stress design (ASD) in section 4. The system effect factor accounts for the measurement uncertainty when there are multiple defects of a similar size. Use the Result Plot option to plot the dimesionless defect (1-d/t versus X/L), and the critical defect. The results for each n, m, combination are tabled at the bottom of the page.
