Рекомендации по повышению выявляемости продольных дефектов внутренней поверхности труб при магнитном методе контроля

Abstract

The task of increasing the detection of longitudinal internal defects during magnetic flaw detection of oil grade pipes is very relevant and has not yet received a practical solution. This is especially true of the problem of detecting defects whose depth is no more than 5% of the nominal wall.
