| 摘 要： | 漏磁检测技术广泛用于石油和天然气管道腐蚀缺陷的在役检测.传统的一维漏磁检测技术通常检测管道径向的漏磁信号,只能反映缺陷的深度信息,对于任意形状的缺陷的评估则无能为力.要反映不规则形状的缺陷的特征,提高缺陷检出率,则须使用三维漏磁检测技术.三维漏磁检测系统要采集和处理大量的数据,系统相对复杂.本文提出的三维漏磁检测实验平...

| Abstract: | Magnetic Flux leakage(MFL) testing technology is widely used to detect the corrosion defects of the oil and gas pipelines on-line.The traditional 1-D MFL testing technology is usually employed to measure the leaked field in the direction of radius and can only characterize the depth of the defect.For arbitrary-shaped defects,it is ineffective.To characterize the irregular defects and enhance the capability of inspection,the 3-D MFL testing technology is required.There is substantive signal to be sampled and... |
