MFL Testing Non-destructive Testing of steel pipes

Magnetic Flux Leakage (MFL) Testing
A nondestructive testing method used to detect corrosion, cracks and other defects in ferromagnetic materials such as steel pipes and pipelines.
AC and DC Magnetization
Two different magnetization methods used in the magnetic flux leakage testing process to generate magnetic fields to detect defects in materials.
3D Imaging Technology
Technology used to reconstruct a 3D image of a defect from a magnetic flux leakage signal, which helps to more accurately assess the size and shape of the defect.
Empirical Mode Decomposition (EMD)
A signal processing technique used to separate noise and extract the effective components in the magnetic flux leakage testing signal.
Intelligent Algorithms
A variety of algorithms, including machine learning and deep learning, for automatically analyzing and interpreting magnetic flux leakage testing data.
Adaptive Filtering
A signal processing method that can dynamically adjust the filter parameters based on the input signal characteristics to optimize the signal processing effect.
Wavelet Transform
A mathematical tool widely used in signal processing, especially for the analysis of non-stationary signals such as magnetic flux leakage detection signals.
Sensor Lift-off Value
The distance between the sensor and the surface being measured, which has an important influence on the detection results.
Transient Simulation Analysis
Simulation of dynamically changing processes, such as when detecting fast-moving defects.
Forward Calculation Model
A model used to predict how the magnetic flux leakage signal will be formed under given conditions.
Inverse Calculation Model
A model designed to infer defect characteristics from actual measured data.
Smart Pigs (Internal Inspectors)
Automated equipment used in long-distance pipelines for internal inspection and maintenance work, including magnetic flux leakage detection.
Infrared Wireless Transmission
A method of transmitting magnetic flux leakage detection signals for rotating parts or difficult-to-reach areas.
Corrosion Scanner
A professional instrument specially designed to detect corrosion defects on the upper and lower surfaces of tank floors or other structures.
Non-destructive Testing (NDT)
A general term for a series of technologies that detect objects without destroying them, and magnetic flux leakage testing is one of them.
