PRCI PR 3805 RSTRENG
Calculate PR-3-805 RSTRENG piping level 0 corrosion defect assessment for blunt defects (corrosion defects or other defects). The level 0 assessment is useful as a screening check. The allowable defect length is calculated from the maximum defect depth. The calculation is taken from ASME B31G 1999 (original ASME B31G). The level 0 check is suitable for blunt defects of all types, including corrosion, mechanical damage and grinding repairs etc. For crack type defects the NG-18 crack defect calculators are recommended. The RSTRENG method (effective area method) can also be used for blunt type defects. The temperature derating calculation is from ASME B31.8. Material specific test data should be used if it is available. Defects failing the level 0 check should be checked with a level 1 or level 2 assessment (see module links below). Use the level 1 assessment for simple defects from defect length and depth using the 0.85 RSTRENG equation. Use the level 2 assessment for complex defects from the defect river bottom profile using the RSTRENG method or effective area method.

CALCULATOR : PR-3-805 RSTRENG Level 0 Corrosion Defect Screening Assessment [FREE] ±
Calculate defect screening assessment and allowable defect length from the maximum defect depth for PR-3805 RSTRENG. The allowable defect length is based on the original ASME B31G (1999). Defects which fail the screening assessment require further assessment, or repair.
