Magnetic Flux Leakage (MFL-tool) - нефтянники нужны...

Чем дальше, тем интересней, и интересней...

A multidiameter MFL tool suitable for pipelines with diameters ranging from 28 to 42" has been developed for the **** pipeline. This tool is denoted the MDPT (Multi Diameter Pipeline Tool), and has so far been used for inspection of a handful of pipelines

ну я, предположим, прежде чем в форум лезть все-таки в словарь посмотрела, да?
Только в данном случае это "рассеяние магнитного потока" (что оно делает в нефтепроводе?) или "Электромагнитный контроль утечек"? Вот чего я понять не могу...

"Magnetic flux leakage (MFL) is the oldest and most commonly used in-line inspection method for finding metal-loss regions in gas-transmission pipelines. MFL can reliably detect metal loss due to corrosion and, sometimes, gouging. In addition, while not designed for this purpose, MFL can sometimes find other metallurgical and geometric conditions[Bubenik98, Grimes92" - вот отсюда http://www.battelle.org/pipetechnology/MFL/MFL98Main.html#Introduction

Magnetic-flux leakage

1. n. [Production Logging] ID: 10946

A distortion of the magnetic flux that has been introduced into a casing by a low-frequency electromagnet or permanent magnet. The principle of flux leakage is used to detect casing corrosion, since flux leakage is caused by rapid changes in the thickness of the casing and by pits and holes in either the internal or external wall. Flux leakage distorts the magnetic-flux lines and induces a signal into an electric coil moving past it. In-situ flux-leakage measurements make use of this effect by placing coils on or close to the casing wall, azimuthally distributed to cover the entire wall. The results are often combined with a high-frequency, eddy-current measurement, designed to detect flaws only on the inner wall.
