Magnetic Flux Leakage Detection of Corrosion Damage in Prestressed Concrete Poles

2015
Urban infrastructure includes large amounts of concrete poles which support power lines, communication cables, and street lighting. These poles are made of spun concrete with embedded pre-stressed reinforcement steel. The chemical environment at the ground-air interface, in combination with tensile prestressing and possibly low concrete cover, promotes

The research of defect detection test system based on magnetic flux leakage

Proceedings of 2011 6th International Forum on Strategic Technology, 2011
According to the defect characteristics and the failure mechanisms, the defect detection technique of rail is discussed based on the magnetic flux leakage (MFL), and a test system of magnetic flux leakage based on AT89C51 is proposed. This paper firstly introduces the theory of magnetic flux leakage, and then combining with electron and circuit theory ...

Adaptive Local Flaw Detection Based on Magnetic Flux Leakage Images With a Noise Distortion Effect for Steel Wire Ropes

IEEE transactions on industrial electronics (1982. Print)
A steel wire rope (SWR) is widely used in industrial scenarios because of its high strength and toughness. To avoid accidents that local flaws (LFs) can cause, SWRs should be inspected regularly.

Nonlinear model of flaw detection in steel pipes by magnetic flux leakage

NDT & E International, 1995
Abstract A numerical model of crack detection by magnetic flux leakage that takes into account the saturation of the induction flux density with the applied field is developed. The model contains no free parameters and is validated with detailed measurements of materials properties and magnetic fields reported by Forster.
