Research on Eddy Current Testing Technology of Bimetallic Composite Pipes
摘要
The eddy current testing study was conducted for the surface defects of bimetallic composite pipe 360QS/825 nickel‐based alloy lining, and the eddy current testing model was designed using ANSYS Maxwell finite element software to simulate and analyze the response of the coil probe with different excitation frequencies to the corrosion defects. The simulation results show that when the excitation frequency of the probe is increased, the change of magnetic induction intensity at the defect also increases, which confirms that increasing the excitation frequency helps to increase the resolution of the coil. At the same time, eddy current testing experiments are conducted for bimetallic composite pipes, and the relationship between bimetallic composite pipe lining defects and weld seams and signals is verified through experimental analysis. The preliminary quantification of pipe defects, is achieved in this paper.
