摘　　要：首先介绍了串列超声检测的原理,然后简述了国家石油天然气管网集团及中国石油天然气股份有限公司的相关企业标准、壳牌标准、DNV GL标准关于SAWL(直缝埋弧焊管)、SAWH(螺旋埋弧焊管)、HFW(高频电阻焊管)的串列超声检测要求、串列超声检测参考反射体的制备方法及相关计算,最后探讨了串列超声检测探头布置和串列超声检测自动探报警后的复查方法。并明确,在超声波自动检测中引入串列超声检测,能有效保障焊管焊缝区域的全覆盖,有助于提高焊管产品质量。The principle of serial ultrasonic testing was firstly introduced,followed by a brief description of the relevant enterprise standards of the National Petroleum and Natural Gas Pipeline Network Group and China National Petroleum Corporation Limited,Shell standards,the requirements for serial ultrasonic testing of SAWL(straight seam submerged arc welded pipe),SAWH(spiral submerged arc welded pipe)and HFW(high-frequency resistance welded pipe)welded pipes,the preparation method of serial testing reference reflectors and related calculations.Finally,the layout of serial ultrasonic testing probes and the review method after automatic detection of serial testing alarms were discussed.And it is clear that full coverage of the weld seam area of welded pipes by introducing ultrasonic automatic detection into serial inspection can help to improve the quality of welded pipe products.
