... on the “API 581-2000” code (Risk-Based Inspection Base Resource), the failure mechanisms of power station boilers have been studied, and the high-temperature smoke erosion factor and high-temperature creep factor have been calculated. Then, considering specific situations in China, such as material quality...

... no significant strain reversals in the wrinkled pipe segment. The final failure was a “tearing” failure resulting from monotonic application of an axial load not aligned with the axis of the pipe. In order to verify this failure mechanism and to determine the characteristics contributing to its formation...

... is a typical failure mechanism, the probability of HEP failures increases with unit age. The main steam (MS) piping system is one of the most critical HEP systems. Weldment failures are typically due to a combination of high temperature creep and fatigue. Industry best practices include (1) the evaluation...
