Ultrasonics
Mechanized Pulse Echo
We offer the following techniques to our
customers:
- Angle beam mechanized shear wave. Code
compliant AWS, ASME.
- Straight beam mechanized. For erosion
corrosion three-dimensional mapping.
Erosion/Corrosion
- C-scan color maps
- Tabulated thickness data
- Histogram and statistical analysis
- B-scan cross-sectional profiles
- A-scans to differentiate inclusions from corrosion
Flange Seal Inspection
NQS has obtained a method to quantify
degradation of flange connections prior to leakage and without
opening the flanged connection.
Time of Flight Diffraction
- Because no ionizing radiation is used, the inspection does
not interfere with the production process. TOFD can therefore be
executed during the day shift. There is no need to transfer
components to the designated X-Ray area.
-
Associated logistic problems and cost do
not exist.
-
Thickness variations do not greatly affect
the inspection speed. Also very thick materials can be examined
in the same efficient manner.
-
The TOFD data is very accurate and is
presented in an easily understood format. All data is stored for
future reference, such that any differences between the
situation after a period in service and the production situation
can be easily established. The data can be utilized to for the
basis for life time and inspection interval extension.
-
Improved inspection sensitivity due to the
insensitivity to defect orientation.
-
Proof of coverage by means of encoded
positioning.
Video Imaging
NQS utilizes the BTX-QL (Quick Look) AC/DC
system. It has recording capabilities and utilizes centering
devices for diameters ranges 4" - 6" and 8" -
12".
Hardness Testing
Equotip: The hardness measurement carried out with the portable Equotip
hardness tester is a dynamic method predicated upon the principle of energy
measurement. This method is used to determine the hardness values of steel
and cast steel materials. The extent of testing shall be defined per
customer specification.
Telebrineller: The "Telebrineller" instrument for measuring
Brinell hardness is a portable instrument, which uses standardized metal bars of
known hardness values as a comparison to the hardness of the specimen under
examination. A telebrineller microscope containing measuring reticula is
used to make comparison measurements between the diameter of the impression on
the bar and the diameter of the impression on the specimen. This procedure
is defined in NQS-HE6001 Rev 0.
