Abstract

Abstract

This paper focuses on the burst pressure of Inconel 690 tubes with fretting wear defects. High-temperature burst test and eddy current testing on the defect size of tubes were conducted. Based on the normal distribution, a burst pressure prediction model and a defect depth prediction model with uncertainty are established. The direct cumulative and simplified statistical methods are used to calculate the burst pressure of the tubes with uncertainty. The results show that a more conservative prediction value of the burst pressure can be obtained by using the direct accumulation method to include the material properties, the burst pressure prediction model, and the 95th percentile worst-case scenario of eddy current testing. And, the simplified statistical method is used to take into account the material properties, the burst pressure prediction model and the uncertainty of eddy current detection, which can effectively reduce the over-conservative problem caused by direct accumulation error.
