| Abstract: | The mechanical properties and the fracture toughness of weighty oil catalytic regenerator were determined by the fracture mechanics theory and the test technique. The typical defect of the under part of the catalytic regenerator was evaluated in terms of the standard for pressure vessel defect evaluation (CVDA-84). The permission dimensions of all defect types at different under parts of the catalytic regenerator were calculated, which can be used as the evaluation norm for defects of the under part of the catalytic regenerator in nondestructive testing. |
