| Nondestructive
Examination (NDE) provides an accurate evaluation
of the condition of your facility's equipment and
materials. Whether your equipment is operating or
down for maintenance, NDE can pinpoint defects
and flaws within your equipment and save you
costly downtime later. SS&A is staffed with
highly qualified and experienced NDE Technicians.
Our training and certification is performed in
accordance with ASNT-TC- IA.
SS&A's
NDE expertise is in the following areas:
Ultrasonic Examination
(UT)
This method
is commonly used to examine for surface and
subsurface discontinuities, the depth and exact
size can be determined by use of the proper
technique. Ultrasonic pulses are directed into
the test object which produces echoes and
reflections which then indicates the presence,
absence and location of flaws, interface and/or
discontinuities. UT for thickness determines
thickness or reveals corrosion discontinuities
near the surface or deep within components or
structures. It offers the advantage of examining
components without removal or disassembly.
Typical applications are examining a tank or
pressure vessel to determine its mechanical
integrity or examining a rotating equipment shaft
for possible fatigue cracks in areas of high
stress concentrations.
Magnetic Particle
Examination (MP)
MT can be used only on
Ferromagnetic materials to reveal surface
discontinuities and to a limited degree, those
located slightly below the surface. Its primary
use is to examine surface discontinuities.
Typical MP applications are the examination of
gears, welds and castings. SS&A provides both
visible and wet fluorescent examinations that can
be done in the field or in-house.
Liquid Dye Penetrant
Examination (DP)
DP is used to detect
discontinuities which are open to the surface of
the material being examined. This method may be
used for ferrous and nonferrous materials. DP
examination is used for the detection of surface
discontinuities such as cracks, seams, laps,
laminations or porosity. SS&A provides both
visible and wet fluorescent examinations that can
be done in the field or in-house.
Vibration Analysis (VA)
VA is used to
determine machinery condition and diagnose
impending problems as well as track and evaluate
rotating machinery to improve reliability and
on-line availability.
