本文介绍一种关于小尺寸煤气钢管涡流检测方法。通过研究检测钢管外部缺陷对所需磁化作用的影响,研制成功一种带有电磁铁的内部探头。该探头能检测出管子表面的腐蚀点。本文也将报道有关这方面试验结果。
This article describes a method for eddy current testing of small size gas steel tubes. By studying the influence of external defects on the magnetization of steel tube, an internal probe with electromagnet was successfully developed. The probe detects the point of corrosion of the pipe surface. This article will also report on the results of this experiment.
