俄罗斯的新型电涡流式钻柱无损探伤仪

A NEW RUSSIAN DRILL PIPE FLAW DETE- CTOR WITH ELECTRICITY BOW WAVE

概述钻杆柱疲劳裂纹检测的意义和在电涡流传感器原理的基础上 ,介绍了俄罗斯专家开发的新型电涡流式钻柱无损探伤仪的组成结构 ,功能。经实验检测 ,该仪器工作性能稳定可靠 ,结构紧凑 ,显示影像的效果非常清晰、准确。

This paper discusses the meaning of deterting fatigue crack of drill pipe,and presents the working principle of electricity bow wave sensors.On the basis of that,the structure and function of a new Russian drill pipe flaw detector with electricity bow wave are introduced.Through lab.detecting,the results show that the working performance of the flaw detector is stable and reliable,effecs of image showed are very clear and accurate.
