Owensby & Kritikos,
Inc. (O&K) has the capability to perform eddy-current
testing on non-magnetic tubular materials. The company supports its current
client base and has the capability to work in geographic locations that are
suited to per diem support projects.
Remote Field inspection is applied
to carbon steel and certain alloys with carbon content.
The Corestar
system currently in use has the capability to record data,
evaluate multiple frequency inspections and produce in-field
reports for immediate data acquisition and client results prior
to closure of the heat exchanger.
HOW IT WORKS
Eddy Current Testing (ECT) is an electromagnetic test method
widely used for flaw detection and sizing of ferrous and non-ferrous conductive
materials. The test unit drives current through a test probe which induces a
varying magnetic field around the coil.
When the coil is coupled to the test piece, a secondary current
(eddy current) is generated. Changes in the test piece such as
permeability, conductivity, homogeneity and flaw geometry will
cause changes in the eddy current field. These changes are
compared to a representative calibration standard for flaw
evaluation.
FEATURES
Corrosion, I.D. and O.D. pitting,
cracks, and mechanical wear are some of the flaws that can be accurately
identified and measured.
ECT has a wide range of testing applications and is utilized by
aerospace, petrochemical, power generation, manufacturing and other industries.
Codes and specifications for ECT have been developed by ASME, and ASTM, as well
as armed forces from around the world.
Owensby & Kritikos,
Inc. invests in the technical expertise of its personnel through method specific
training courses and outside agency certification programs.
BENEFITS
Reduced Inspection Time - Eddy Current testing can
provide more reliable and faster speeds than with other test methods.
Permanent Record - Formal on-site reporting
and inspection data can be printed or stored and saved to a variety of
recording media. This allows data to be archived, or retrieved later for
review.
