射线底片评定中深孔缺陷是作为危害性缺陷评定,但对于深孔的评定按照目前实施的NB/T47013-2015承压设备无损检测标准却有较大的随意性。本文主要介绍通过实验在不同的射线源与厚度情况下,在底片评定中对于深孔的评定是否合理。
Radial film defects in the assessment of deep hole defects as a hazard assessment, but the assessment of deep holes in accordance with the current implementation of the NB / T47013-2015 nondestructive testing of pressure equipment has greater freedom. This paper mainly introduces whether the assessment of deep holes in film evaluation is reasonable or not through experiments under different radiation source and thickness conditions.
