近年来国内生产的几条重要管线 ,如陕京管线、苏丹管线和兰 成 渝管线 ,都要求厂家依据ＡＰＩ或ＧＢ/Ｔ 9711标准用连续超声波探伤设备对成形后钢管作全焊缝超声波自动探伤。因而研究和采用一种有效的在线超声自动化探伤系统成了钢管生产厂的必然选择。焊管探伤采用不同的超?
In recent years, several domestic production of several important pipelines, such as the Shaanxi-Beijing pipeline, Sudan pipeline and Lancheng-Chongqing pipeline, require manufacturers based on API or GB / T 9711 standard ultrasonic flaw detection equipment for the pipe after forming the whole weld ultrasonic automatic flaw detection . Therefore, researching and adopting an effective on-line ultrasonic automatic testing system has become the inevitable choice of steel pipe manufacturing plant. Welded pipe testing using different ultra?
