摘　　要：介绍了标准中检测焊管典型缺陷的超声波检测探头布置方法。提出了钢管焊缝纵向伤检测方法、横向伤检测方法及串列式检测方法。通过不同的检测方法灵敏度校验、耦合监视、检测能力的确认,确保该检测方法可满足油气管道相关标准要求。该检测系统结合自动化校准模式,通过对比样管人工刻伤对应波形位置,可以清晰地看出样管上人工检测缺陷的位置误差、漏检和误报等情况,为钢管自动探伤工作带来方便,并提高了钢管检测质量。Described here in the paper is the probe arrangement method for detecting typical defects in the pipe manufacturing process as specified under applicable standard.And also proposed are the longitudinal flaw detection method,transversal flaw detection method,and serial detection method for steel pipe welds.Owing to verifying the sensitivity,coupling monitoring,and confirming the detection capability of different detection methods,the said detection methods are ensured to meet the requirements as specified under applicable standard for oil and gas pipelines.Combined with the automatic calibration mode,and comparing the corresponding waveform positions of the artificial scratch on the reference tube,the detection system is capable of clearly identifying the position error of the manually-measured defect,and any defect-missing and false alarm of the the reference tube,which brings convenience for the automatic detection of the steel pipe,and improves the inspection quality of the steel pipe.
