| The
Situation
The component safety in chemical plants, petro-chemical plants, fossil and nuclear power
plants, aviation, etc. is indispensable. Flaws and material defects such as cracking, weld
flaws, corrosion and service- induced stresses are only a few examples leading to
component failure, often prior to their designed life span. State-of-the-art methods and
technologies are required, especially to protect public health, for economic inspection
and testing solutions.
Our
Solution
EMAT technology, combined with Phased Array techniques (developed by
IZFP), uses horizontally polarized shear waves (SH-wave) to improve the inspectability of
stainless steel welds, dissimilar metal welds, buttered welds, cladding, etc. These, and
other components can now be completely inspected regardless of access considerations due
to the virtual transparency of the material to horizontally polarized shear
waves. The inspection for hard
to detect flaws such as intergranular corrosion cracking (IGSCC) in stainless steel piping
welds or cast stainless steel welds is made possible with unmatched accuracy and ease.
Our
Systems EMAT (Phased Array) systems
are designed for a variety of applications, consisting of
two portable components, front end unit and base unit. Control functions, data acquisition
and data analysis are performed through the integrated PC. Standard and custom EMAT
(Phased Array) search units are designed and manufactured by IZFP.
Advantages
- Electronic control of the sound beam angle and
shape
- Generation of horizontally polarized shear wave mode
(SH-wave)
- Generation of vertically polarized shear wave mode
(standard shear wave) and Rayleigh wave mode
- No acoustic coupling medium required.
Software
- MS-DOS© based data acquisition and analysis
software
- Menu controlled setup of parameters such as beam
angles, frequency, burst length, amplification, etc.
- Menu controlled inspection parameter setup for exam
area and volume, display length and resolution, multi probe configuration, etc.
- Integrated data analysis including reporting and
hard copy; export of UT data to a variety of data formats
- Management of
unlimited amounts of UT-data,
including pertinent parameters and unlimited number of A-scans
- Search unit database.
