MATERIALS TESTING AND EVALUATION
The test
lab offers a wide variety of services including non-destructive
testing, chemical analysis, mechanical testing and metallurgical
investigation. A licensed professional engineer can provide
consultation services in many areas, including failure analysis,
test interpretation, and material selection. All tests are
conducted on calibrated and certified equipment traceable
to the NIST, in accordance to MIL-STD-45662A, ANSI/NCLS-Z540-1
and ISO/IEC 17025 requirements.
Non-Destructive
Testing
Non-destructive
testing capabilities include eddy current testing,
ultrasonic testing, hydrostatic pressure testing, magnetic
particle testing, fluorescent or dye penetrant, surface
roughness and dimensional inspection. Dimensional measurements
can be made with a variety or gauges, laser micrometer,
optical comparator or coordinate measuring machine.
ID can be visually inspected with a borescope if size
permits.
Chemical
Analysis
Chemical
analysis with a Plasma Emission Spectrometer is used
to determine the composition of elements found in various
metal alloys. This process is routinely used for alloy
identification or verification of material as well
as full quantitative analysis.Corrosion resistance
testing performed on many different alloys in various
media is used to confirm product integrity or aid in
material selection.
Mechanical
Testing
Typical
testing services include tensile testing, Rockwell
hardness, Knoop and Vickers micro-hardness, stress
rupture testing, flaring, flattening and bend testing.
Tensile
testing is performed on most mill products. Stress-strain
curves are provided on request.
Hardness
tests are performed on most materials regardless of size.
When required,
mocro-hardness testing will be performed.Stress
rupture or creep testing is available for materials up to
2000
degrees F.
Flaring,
flattening, bending and micro examinations are performed
to evaluate the weld integrity
of the
tube.
Metallurgical
Investigation
Microscopic
and macroscopic services as well as metallurgical interpretation
of results are provided by our trained staff.Grain
size determination,inclusion count, micro structure
analysis, phase identification and weld integrity are
just a few of the tests which are performed by our
metallurgical staff.
Consulting
Services
Failure
analysis, material recommendations and development
of special tests are provided by a licensed professional
engineer. Our staff provides and independent analysis
and interpretation of the facts when a dispute exists
over test results or cause of failure.
