Embodiment Construction
[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0055] According to the embodiment situation of the complete implementation of the inventive method is as follows:
[0056] In order to verify the reliability of this evaluation method, it is necessary to compare its evaluation results with existing evaluation methods.
[0057] The existing bending moment evaluation methods mainly include the following:
[0058] 1) ASME section method
[0059] In the evaluation method defined by ASME, the defects detected by the pipeline defect detection system are usually treated equivalently, and the irregular defects are equivalent to a defect of equal depth, and the depth value is equal to the maximum depth of the detected defects. value:
[0060] a eq =max a(ξ)
[0061] Therefore, the evaluation and calculation results will over exaggerate the influence of defects on the ultimate bending mom...
