摘要:
为了将微磁检测技术更好地应用于双金属复合管的缺陷检测,针对双金属复合管结构的特殊性,提出了一种新型微磁检测技术。以人工预制腐蚀缺陷的双金属管为研究对象,采用自主研发的微磁检测仪,对复合管管体及焊缝腐蚀缺陷进行检测。研究结果验证了微磁检测技术在复合管管体及焊缝缺陷检测中的可行性,同时针对焊缝缺陷,将采集到的信号剔点、差分放大及滤波处理后,微磁检测技术仍有较好的检测效果。
Abstract:
In order to make the micro-magnetic detection technology be well applied in defect detection of bimetal composite pipe, aiming at the special structure of bimetal composite pipe, a new type of micro-magnetic detection technology was put forward. With artificial prefabricated corrosion defects of bimetal composite pipe as the research object, adopted the independent research and development micro-magnetic detector, to test the corrosion defects of composite pipe body and weld. The results proved that the micro-magnetic detection technology is feasible for detecting the corrosion defects of composite pipe body and weld. Meanwhile, in view of weld defects, the acquired signals were picked point, after differential amplification and filtering processing, micro-magnetic detection technology still possesses better detection effect.
