摘要
超声波无损检测技术被广泛用于压力容器制造缺陷检测及质量控制,针对压力容器封头厚度控制的实际需要,在实际生产中选取三类典型封头进行厚度测量和结果分析,对测量工艺对封头质量控制的作用、意义和影响进行分析研究。分析表明,超声波测厚点分布和测量结果的记录顺序对后期结果分析和质量控制方式改进有重要影响,发现球形封头的1点区、椭圆封头的0点区、蝶形封头的4点区等部位为主要成型区,是测厚重点部位和内部质量控制重点部位,提出在同类封头的超声波厚度测量及缺陷探伤时对该部位加强重点检测和跟踪控制的建议,从而提高同类封头测厚检测的有效性和成型质量。
The ultrasonic nondestructive testing technology is widely used in defect detection and quality control of the pressure vessel manufacturing.For the practical needs of the pressure vessel head thickness control,three kinds of typical heads are selected for thickness measurement and results analysis in the actual production;and the role,significance and influence of the measurement technology on the quality control of the heads are analyzed and studied.The analysis shows that distribution of the ultrasonic thickness measurement points and the recording sequence of the measurement results have important influence on the later result analysis and the quality control mode improvement.It is found that 1 area of the spherical head,0 area of the elliptical head and 4 area of the butterfly head are the main forming areas,which are the key parts of thickness measurement and internal quality control.Finally,suggestion of strengthening the key detection and tracking control of the ultrasonic thickness measurement and defects detection of the similar heads is proposed so as to improve the effectiveness and forming quality of the similar head thickness measurement.
