Magnetic Flux Leakage Testing Equipment

On a corrosion spot a leakage field will arise.

Magnetic flux leakage testing equipment.

It is vital that magnetic flux leakage ndt equipment used for storage tank floor inspection is designed to handle the environmental and practical field conditions that are consistently present. We have a complete range of products such as ultrasonic testing equipment eddy current testers and magnetic memory testers. During inspection a magnetic circuit of sorts forms between the part and the probe. An inspection technique that detects volumetric changes magnetic flux leakage mfl testing is facilitated by tank floor mapping utilizing today s latest computerized equipment.

Magnetic flux leakage tfi or transverse field inspection technology 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. With mfl a strong magnet induces a magnetic field in the material. Two strong magnets generate a static magnetic field that saturates the tube wall fig.

Mfl test methods are used for the detection of outer surface inner surface and subsurface discontinuities in magnetic steel tubular products of uniform cross section such as seamless and welded tubing. At areas where there is corrosion or missing metal the magnetic field leaks from the steel. The magnetic field induced in the part saturates it until it can no longer hold any more flux. Flux leakage technology can also be used for inspecting ferrous parts and products such as wire rope sucker rods and coupling stock.

Magnetic flux leakage mfl testing is a widely used non destructive testing ndt method for the detection of corrosion and pitting in steel structures. The flux overflows and leaks out of the pipe wall and strategically placed sensors can accurately measure the three dimensional vector of the leakage field. The course is tailored to custom fit magnetic analysis corporation s encircling coil and rotary flaw inspection test methods. Magnetic flux leakage mfl magnetic flux leakage mfl is a magnetic method of non destructive testing that is used to detect corrosion pitting and wall loss in steel structures.

Training is conducted with mac s user friendly electronics which aid in the ability to learn and retain the information being presented. Mfl is often used for integrity assessment of pipelines and storage tanks but the principle can be applied to assets in any industrial sector. The larger the corrosion the larger the leakage field. Magnetic flux leakage mfl is a tube testing technique primarily designed for the rapid testing of ferromagnetic tubes with non ferromagnetic fins wrapped around them such as in air fin coolers.
