Should one use the same equation? Through case verification and comparison analysis, the remaining strength of corroded pipes are evaluated by the ASME B31G by four levels, which helps evaluators easily choose different levels of evaluation according to the difficult and easy level of field operation, more and less data, and evaluation accuracy. This standard is also available to be included in Standards Subscriptions.

The equation for SF for z equal or higher to 50 is given on page 6. Based on the collected blasting test data of full-size pipes in 67 groups, the forecasted failure pressures were calculated respectively by new- and old-edition ASME B31G and the RSTRENG and compared with the actual blasting pressures.
On the other hand, the ASME B31G is not fit for large-diameter and high-strength pipes and needs to be improved in its application range.
Is Sflow more or less the yield stress and Sf the failure stress for the pipe?

A Study on New Edition Assessment Criteria for the Remaining Strength of Corroded Pipeline
For z less than v31g, the M equation is on the bottom of page 5; for z over 50, the M equation is at the top of page 6.
I’m trying to understand some of the background. In recent years, corrosion is becoming more and more serious in Chinese oil and gas pipes, so to determine the remaining strength of corroded pipelines can help prevent and control the leakage accidents.
