摘要
通过实例介绍了不锈钢列管存在缺陷时,缺陷的深度、长度、开口宽度和延伸方向对识别其涡流信号的影响;以及列管发生均匀腐蚀减薄时涡流探伤和涡流测厚方法的互补运用。
The paper introduces the influence of the depth,length,width and direction of the crack defect on the identification of the eddy current signal in stainless steel tubes through examples.And the complementary application of eddy current testing and thickness measurement in uniform corrosion and thinning of the Tubes.
