摘要
针对核电工程中的液体渗透检测,从检测的关键控制点如组合渗透检测材料的选择,检测工件的表面状态,低温、高温条件下检测工艺的修正,检测结果的评判时机等方面提出了质量控制要求,针对不同检测单位及检测人员对于检测评判结果的差异性进行了分析,提出了控制检测时机、加强检测过程控制、针对显示结果需要分清相关显示的重要意义,便于判定缺陷的形状和性质,对密集性的小缺陷应注意分析缺陷性质等解决减小差异的基本措施,并对检测时发现的不一致现象进行了归零处理的意见和建议,有助于提高检测效率减小差异,从而推进技术进步和规范检测。
For the liquid penetration inspection of nuclear power project,the paper shows us the detection principle,key control points such as the choice of penetrant materials,the surface condition of the work-piece,correction and detection technology in low temperature as well as in high temperature,and the time when the requirements for quality control test results evaluation can be put forward,etc.In view of the differences in the results evaluation,the differences of detection units and test personnel were analyzed.The paper put forward the control of the detection time,the strengthening the process control as well as the detection results.The paper also points out that it is significant to distinguish corresponding displays in order to easily determine the shape and nature of defect.For densely displayed small defects,the defect properties should be clearly understood to reduce the difference.As for the inconsistent phenomenon found on the detection,return-to-zero processing opinion is suggested.The abovementioned measures can help to improve the detection efficiency and to reduce differences,so as to promote technological progress and specification testing.
