It is of great importance to improve the spatial resolution and sensitivity of magnetic flux leakage (MFL) sensors for small cracks characterisation on pipelines. To solve these problems, a novel pulsed magnetic flux leakage (PMFL) method, using magnetic head (MH) and a side placement of tunnelling magnetoresistance (TMR) is proposed. Two symmetrically

Magnetic Flux Leakage signal processing in strip steel flaw area detection
2013 6th International Congress on Image and Signal Processing (CISP), 2013The strip steel is widely used in industries, but there always exists some flaws during its manufacturing. The flaws are difficult to be detected and the analysis of the data obtained from Magnetic Flux Leakage (MFL) inspection of the strip steel is quite a challenge.

Magnetic Flux Leakage Detection Technology for Well Casing on Neural Network
2008 International Symposium on Intelligent Information Technology Application Workshops, 2008Well casing integrity is vital for the safe operations of oil wells, and also significant to detect well casing defects. Magnetic flux leakage (MFL) detection technology is widely-used in detecting the defects of various pipelines. Owing to the very complicated environment where well casing is laid in, the system which based on magnetic flux leakage ...

Detection of natural gas pipeline defects using magnetic flux leakage measurements
2013 21st Iranian Conference on Electrical Engineering (ICEE), 2013Magnetic Flux Leakage (MFL) testing is the most widely used non-destructive techniques for the in-service inspection of oil and gas pipelines. This study presents novel approaches to detect defects by employing MFL signals. Estimating the number of defects, locations, and orientations from measurements is a typical inverse problem in electromagnetic ...
