A Study on New Edition Assessment Criteria for the Remaining Strength of Corroded Pipeline

Is Sflow more or less the yield stress and Sf the failure stress for the pipe? Thank you for the help, OKCorall. 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.

Xi’an Jiaotong University; 2. 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.
