摘要
压水堆核电站核岛主系统中的蒸汽发生器产品的管子-管板焊缝焊接后需要进液体渗透检测.主要针对液体渗透检验方法的选择、检验设备器材需满足的要求、检验灵敏度的验证等几方面进行了试验,通过试验对比,确定了密集型排列管子-管板焊缝水洗型液体渗透检验的检验控制流程,且通过产品的检验可以看出,对密集型排列且数量多的管子-管板焊缝进行液体渗透检验时,在检验灵敏度满足要求的情况下,最高效的检验方法为水洗型着色渗透检验方法.
Abstract
The liquid penetrant inspection is required for the weld of tube-tube sheet in steam generator product which was used in the main system of the pressurized water reactor nuclear power plant nuclear island.The selection of liquid pene-trant inspection method,the requirements for the inspection devices,and the verification of inspection sensitivity were in-vestigated.Through experiment comparison analysis,the inspection control process for water-washed liquid penetrant in-spection of densely arranged tube-tube sheet welds was determined.Moreover,the product inspection results showed that when the liquid penetrant inspection was performed using the densely arranged and numerous tube sheet welds,the most ef-ficient inspection method was the water-washed type dye penetrant inspection method under the condition that the sensitivity requirements were met.
