Technology Update
Mac NDT test systems
NONDESTRUCTIVE test instruments
and Systems from Magnetic Analysis
Corporation (MAC) were exhibited at the
Polimeter Comércio e Representações
Ltda booth at Tubotech, São Paulo
in October. Polimeter is MAC’s
representative for Brazil, Chile and
Argentina.
MAC uniquely offers three
different test technologies, eddy
current, ultrasonic, and flux leakage.
MAC’s ability to provide a choice of
technologies is a distinct advantage. By
combining eddy current and ultrasonic
technology, for example, superior
test results can be obtained as each
technique detects the conditions that it
is best suited to find.
Applications include inspecting
welded and seamless tubes as well
as Oil Country Tubular Goods (OCTG)
with or without upset ends. Both
ferromagnetic and non-ferromagnetic
materials can be successfully tested.
Information on the MultiMac® Eddy
Current, Echomac ® FD-4 Ultrasonic,
and Rotoflux® flux leakage test
instruments and systems was available
at Tubotech. The versatile MultiMac
with up to eight test channels can
be used to detect transverse, non-
continuous and/or longitudinal, seam-
type surface defects.
MultiMac operates with encircling/
sector test coils or rotary test probes,
depending upon the specific application
and type of defects that need to be
detected.
The Echomac FD-4 instrument
features up to 32 independent test
channels.
It provides superior performance
for flaw detection, and measurement
of wall thickness, ID, OD, ovality
and eccentricity. Echomac FD-4
can be used with MAC’s rotating
transducer units as well as with new
or existing immersion, squirter and
other couplant type installations.
The Rotoflux tester is available for
transverse and longitudinal flaw
detection. With 48 channels, the
Rotoflux systems meet demanding
industry standards for heavy wall
OCTG tube. A recent system for a
tube mill has the capability of testing
to within 1" from the tube end.
A range of mechanical handling, test
coil platforms, automated controls and
reporting capabilities are also available
from MAC.
Magnetic Analysis Corp is a market
leader in Brazil for eddy current tube
test systems and all MAC equipment
can be delivered with software and
operating instruction manuals in
Portuguese.
