1. The method registers the totality of MSC including those caused
by defects detectable
by main types of flaw detection
(ultrasonic, X-ray, magnetic-particle, eddy-current, etc.) and dangerous places undetectable by the known
techniques.
2. The instrument is the first in
the world to show both positions of dangerous defects and the degree of
their danger, i.e., mechanical stress concentration – MSC.
3. Inspection results are documented by
PC, archived and can be displayed for further analysis or printed out at any
time.
4. The memory volume of the
instrument is more than 43,000 measurement points (1 week of operation).
Duration of storing data in the instrument is more than 6 years (non-volatile
memory).
5. It is not required to remove
insulation (up to 3 mm thick) from the base metal of the item to be tested.
6. Function-value effectiveness
of "StressVision-2" is significantly higher than that of the best instruments
used for this purpose.
7. Operator's qualification requirements are considerably lower than the
requirements imposed on operators of magnetic-particle flaw detectors.
8. The instrument is controlled by one operator
9. Time of testing, for
example, a whole weld and heat-affected
zone, 250 mm on either side (from the beginning of measurements to dumping
MSC and PMSD maps to the PC screen or to printing) for a pipe 1020 mm in diameter (1410 points) is 2.5 hours.
10. Maps of stress distribution of the inspected area of construction can be made in reliance on measurements taken at a depth of 0-3 mm and 0-7 mm (Two layers) with an included standard probe.
