Quantitative non-destructive evaluation of wall thinning of inner side in carbon steel piping is a difficult and urgent issue for safety of nuclear power plants, especially compared to NDT of non-magnetic material. In this research, The feasibility of the magnetic saturation PECT method for wall thinning detection in carbon steel piping is proposed and validated.Firstly, the simulated polarization approach is adopted for the calculation of the static magnetic field distribution generated by the electromagnetic magnet, then the material permeability distribution is predicted according to the B-H curve of the targeted material. Finally the efficient magnetic saturation PECT forward simulation tool is updated for the carbon steel based on the Ar (reduced A) method and the Fourier series strategy to validate the wall thinning detection in carbon steel material.

与非磁性材料的无损检测相比，碳钢管道内壁减薄的定量无损检测是核电站安全运行中的一个难点和紧迫问题。本文提出并验证了磁饱和PECT方法用于碳钢管道壁厚减薄检测的可行性，首先采用模拟极化法计算电磁铁产生的静磁场分布，然后根据目标材料的B-H曲线预测材料磁导率分布。最后，基于Ar（约化A）方法和傅立叶级数策略，对碳钢材料的磁饱和PECT正演模拟工具进行了改进，验证了碳钢材料的壁厚减薄检测。
