油气管道内表面涡流无损检测系统设计
Design of Eddy Current Non-destructive Testing System for Inner Surface of Oil and Gas Pipelines
摘要
Abstract
A multi-channel differential detection probe is designed based on the principle of eddy current,reducing the interference of common mode signals through the differential signal of two coils.With the application of a power detector,the amplitude of defect signals is quickly extracted,which is faster and more intuitive compared to digital phase sensitive detection.An upper computer platform is built to collect multi-channel defect signals,and the differences in pit defect signals with different depths and widths are analyzed and compared.The experimental results show that the eddy current non-destructive testing system can effectively detect pit defects with a depth of 1 mm and a radius of 5 mm,and has good resolution ability for defects with different depths and widths.关键词
