WITH more than 25 years in the OCTG
business, Scan Systems Corp tailors
its products and services around the
needs of those working with OCTG
tubing and casing. The company designs
and manufactures products for non-
destructive testing of OCTG materials. Its
latest product uses magnetic flux leakage
(MFL).
Scan Systems focused substantial
capital resources in research and
development, and says that its efforts
have brought state-of-the-art technology
together with MFL techniques that produce
a superior quality inspection in an industry
that has not seen any major advancement
in MFL inspection equipment in more than
30 years.
The Digi-Tech™ MFL Inspection family
of products features custom digital signal
processing software (Digi-Pro™) and
state-of-the-art MFL technology. Scan
Systems Corp can provide users with
options for the total replacement of all of
their existing analogue signal processing
electronics.
The Digi-Tech product line is capable
of performing MFL inspection of OCTG
pipe with wall thicknesses up to 0.625"
and with production speeds up to 150 ft/
min.
Originally created for steel mill
applications, the Digi-Tech M-Series
product line features a four-function unit
specifically designed for high volume,
continuous operationwith lowmaintenance
and high production. The robust M-Series
features a rigid aluminium centre
section frame as the foundation where
all inspection systems are mounted and
integrated, and offers quality steel welded
sub-frame for stability and performance.
The systems also have enhanced pinch
roller systems and improved magnetic
circuits.
Scan Systems offers two models within
the M-Series design, covering the entire
size range of common OCTG materials.
The DT-2100™ equipment is used for
plain-end OCTG materials from 60.3 to
203.2mm (23/8" to 8"), while the DT-3100™
equipment can handle plain-end material
from 114.3 to 355.6mm (4½" to 14").
Inspection methods include magnetic
flux leakage technology for OD and ID
longitudinal and transverse flaws, magnetic
flux density for 100% coverage of the
wall thickness variations, and an eddy
current system for simple comparison
of metallurgical mass and permeability
differences.
