随着中小直径优质焊管生产的发展,非破坏检查的重要性越来越受到重视。和歌山炼铁厂小直径焊管超声波探伤,应用1970年2月安装的克劳特克雷曼公司制造的 ROT—50型探头旋转式超声波探伤装置之后的实际效果显著提高。对直径大于50.8毫米的管材,采用管材一直地向前送入,及探头固定的水浸和半水浸法进行超声波探伤,是保证产品质量的最
With the development of small and medium-diameter high-quality welded pipe production, the importance of non-destructive inspection has attracted more and more attention. Wakayama Ironworks small diameter pipe ultrasonic flaw detection, the application of February 1970 installed CROCKLEMAN company ROT-50-type probe rotary ultrasonic flaw detection after the actual results significantly improved. The diameter of more than 50.8 mm of the pipe, the pipe has been forward to feed, and the probe fixed immersion and semi-water immersion ultrasonic testing is to ensure the quality of the product
