ARTIS EMI Pipe Inspection Systems
BETTER THAN THE REST !
![]() |
The ARTIS family of products are the only EMI inspection systems offered in the marketplace which implement 100% solid state Hall sensor technology for both flaw and wall loss detection!
Products using induction search coils are still missing defects in the tubulars under inspection.
-
OEM's most advanced ARTIS EMI systems solve several key problems which exist with other EMI unit offerings in the marketplace.
-
Other units use induction search coils as the primary
inspection sensor technology which makes it easy to miss
areas of reduced metallic area (wall loss) such as
washouts. While this defect could be seen visually when it
breaks through the outer diameter of the tubular, a large
area of corrosion/erosion could exist on the ID which has
not yet broken through the OD of the pipe, making the defect
undetectable by visual inspection. Since the search coil
cannot detect this type of defect, it is returned to service
with a potential failure looming.
- Other units implement only eight (8) single Hall sensors around the circumference of the pipe for wall loss detection, which offers less than 20% circumferential coverage. As one can imagine, MANY defects go undetected as they pass between the magnetic sensors.
-
Other units implement a single detection function to attempt
to detect all types of wall loss defects, with no regard for
defect size. Research has shown that a smaller diameter defect
disrupts less magnetic flux than a larger diameter defect of
the same depth. This is due to the fact that magnetic flux
leaks from a defect area based on the volume of
the missing metal. This simple fact makes it impossible to
detect all wall loss defects with a single inspection
function. An EMI unit with a single wall loss function can
either be tuned for smaller volume defects or larger volume defects, but not for both. This limitation makes
the EMI unit either
too sensitive for some defects or not sensitive enough for
others. This usually leads to “de-tuning” of the EMI unit
by the operator which makes it extremely easy to miss defects which should
be rejected.
ARTIS units have none of these limitations. OEM's latest generation ARTIS-5 units are the ONLY systems available which are 100% computerized and offer 100% circumferential coverage for both Magnetic Flux Leakage (MFL) and Magnetic Flux Density (MFD) inspection methods.
