FLUX LEAKAGE TESTERS
Magnetic Flux leakage (MFL) non destructive test systems accurately detect defects in heavy-wall magnetic tubing, including oil country tubular goods (OCTG), and parts. Systems are available in sizes to handle up to 16″ (406 mm) diameter tubes. Magnetic flux leakage testing technology allows detection of transverse and longitudinal surface defects on the OD and ID as well as defects within the wall.
ROTARY FLUX LEAKAGE
Magnetic Analysis Corp.’s Rotoflux® electronics are used with a rotary system where the material under test is driven through a rotating headplate. During testing, an electromagnet creates intense flux flow around the material. When a defect interrupts and blocks some of the flux lines, they extend beyond the material creating “leakage flux” that can be detected by the electronics.
ROTOFLUX® Flux Leakage Tester
The electronics are capable of differentiating between ID and OD defects, using a unique multiprobe feature which allows convenient operation at greater speed. A flux measurement circuit is included to indicate whether the test piece is properly saturated. To detect longitudinal defects, the material under test is driven through rotating headplates that include transverse magnetizing coils and test probes.
MAC also offers Rotoflux systems to detect transverse defects where the magnetizing poles are placed in a fixed position perpendicular to the axis of the material under test, and the sensors are rotated around the test piece.
Tubing up to 16″ (406 mm) in diameter and 3/4″ (19 mm) wall thickness can be handled.
This magnetic flux leakage ndt test system accurately detects longitudinal defects in heavy-wall magnetic tubing, including oil country goods, and tubular parts.
- Detection and differentiation of ID and OD defects in heavy-wall magnetic tubing and tubular products, such as oil well pipe. Longitudinal and Transverse defects, as small as 5% on OD and 5% on ID, depending on material type and condition can be detected.
