摘要
采用“非接触式”磁记忆检测技术在输油管道内腐蚀严重管段进行了实验检测，通过对比，给出了抑制干扰、剥离出管道缺陷异常的办法，取得了预期效果。
Abstract An experimental detection is made for the internal corrosion in the buried crude oil pipeline by the ＂non -contacting＂ magnetic memory detection technology. By comparison, a methodology is proposed to suppress any interference and reveal the abnormal defect in the steel pipeline. An expected result is achieved.
