介绍了影响核用锆合金管材涡流检测结果的因素,针对压水堆10×0.7核用锆合金管材的涡流检验,分析了检测中超标信号形成的原因,提出了提取有用信号的措施,以达到去伪存真、准确判定产品质量的目的。
This paper introduces the factors that affect the results of eddy current testing of zirconium alloy pipes. According to the eddy current test of 10 × 0.7 nuclear zirconium alloy pipes in pressurized water reactor, the reasons for the formation of excessive signals in testing are analyzed. The measures for extracting useful signals are proposed to achieve To pseudo-true, accurate determination of the purpose of product quality.
