摘要: 介绍了一种螺旋埋弧焊钢管的超声检测校验方法, 即在现有基础上新增一种校验方法, 通过对新型参考反射体的校验, 作为对大壁厚螺旋埋弧焊钢管的焊缝中部区域超声检测的补充。对该方法进行了详细描述, 并在大壁厚螺旋埋弧焊钢管试制过程中对其可行性和有效性进行了验证。Abstract: This paper introduces a method for calibration of ultrasonic inspection used for spiral submerged arc welded steel pipes, which is to achieve a newly added method for calibration on the basis of the existing practice through the calibration of the new type reference indicators, and the new method can be the supplement of ultrasonic inspection used for the middle area of SAWH steel pipes with large wall thickness. A detailed description of this method was presented in the paper and its feasibility and effectiveness were verified in the trial production of SAWH pipes with large wall thickness.
