摘要
介绍涡流、远场涡流,多频涡流等探伤方法的基本原理及三者之间的关系,并在此基础上着重介绍了远场涡流在电厂冷凝器铜管、不锈钢管探伤工作中的优点,根据现场检验的经验总结出一套相应的检测方法,并对此方法的工作流程作了详细介绍。
This paper introduces the theory of flaw detection for the eddy current,the remote field eddy current and multifrequency eddy current and their relationship.It emphatical introduces the advantage of the remote field multifrequency eddy current on condensator copper pipes of power station and flaw detection of stainless steel pipe.According to field experience,it summarizes a set of related detecting method and detailedly introduces the workflow of this method.
