Magnetic Flux Leakage Testing Equipment

Electromagnetic detection is a very important non-destructive testing method and is widely used. Magnetic flux leakage is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic principle is that a powerful magnet is used to magnetize the steel. When used in combination with other methods, it provides a quick and inexpensive assessment of the workpiece of ferromagnetic materials. With the…See More

ECT For Automotive And Aerosapce

Eddy current testing technology has been widely used in the detection of metal components in the automotive and aerospace industry. In order to ensure the flight safety of the aircraft, the relevant components must be periodically inspected. The eddy current technology is usually used to detect aero-engine blade cracks, bolts, cracks in the screw holes, multi-layer structure of the aircraft, landing gear, wheels and aluminum skin as the…See More

EDM Notch

An electric pulse is a pulse generated by electrons, and a pulse is a process of changing a voltage in a short time. Electropulsing is an unsteady current field generated by a capacitor or an intermittent source. The alternating current we use can be regarded as a pulse current, and one of the cycle processes can be regarded as an electrical pulse. Modern electric pulse technology has developed to the trend of higher frequency and high energy peaks. It has a wide range of applications in…See More

Drill Pipe Magnetic Flux Leakage Detector MFL-308

Posted on October 6, 2019 at 4:30am 0 Comments

Specifications: diameter Φ73 / Φ89 mm, length 9.6m or so

 

Detection speed: 6-20 m / min

 

Acceptance criteria: American Petroleum Institute API testing standards

 

 

 

The main detection principle of the MFI magnetic flux leakage pipeline inspection method is that the workpiece is magnetized (close to saturation) to have a certain magnetic flux density to generate a leakage magnetic field at the discontinuity, and the magnetic field…
