摘要：This paper focused on experimental research on the bursting pressure of steam generator (SG) tubes with typical uniform thinning defects. Bursting tests of Inconel-690 SG tubes with uniform thinning defects were carried out at 350 °C, and the regularity of the test results was analyzed. Based on the results, the prediction formula for the bursting pressure of the defective SG tubes was regressed using the least square method. Results show that the depth of the defects in the tubes is the main factor affecting the bursting pressure of SG tubes. The bursting pressure is negatively correlated with the depth of the defects. The defect length is a secondary factor, and its influence gradually weakens as the defect length increases. This paper provides a data set of the bursting pressure of the Inconel-690 SG tubes with uniform defects at 350 °C, which can serve as support for related research. ?
