对某石化设备过滤器Y型管节点焊缝分别采用JB/T4730.3-2005超声标准和美国石油协会(API)相应的标准进行超声检测,将其结果做了比较,结论是:采用API标准时步骤繁琐,但适用范围广;JB/T4730.3-2005标准当两管轴线夹角较小时可用;执行两种标准检测结果基本吻合。
The Y-tube joints welds of a petrochemical equipment filter were respectively tested by ultrasonic testing according to the JB / T4730.3-2005 ultrasonic standard and the corresponding standards of the American Petroleum Institute (API), and the results were compared. The conclusion is: when using the API standard Tedious steps, but a wide range of applications; JB / T4730.3-2005 standard when the angle between the two axes available; implementation of two standard test results are basically consistent.
