摘要
漏磁探伤法结合磁通量检测法可检出管体内、外壁及内部各种缺陷 ,描绘检测图形曲线。通过长期检测数据积累 ,将有缺陷的和经过解剖对比的石油管道图形曲线资料输入计算机作为缺陷类型模板。检测中由计算机分析缺陷信号 ,与缺陷模板比较 ,识别。
Various kinds of flaws in both inside and outside walls of oil pipes can be detected out by magnetic leakage testing in combination with magnetic flux method. The curves of the detecting data of the pipes with flaws accumulated have been imported into computer as flaw patterns. The pipes harmful to oil well can be distinguished by computer analyzing of flaw signals and comparing with flaw patterns.
