Detection of hydrogen cracking using phased arrays
Hydrogen cracking at high temperatures is characterized by small sizes of defects at the initial stage (about 0.1 mm). Such defects are typical for the oil refining industry and are very dangerous.
To detect hydrogen cracking, the digital focusing antenna method is used, which can be implemented using GEKKO or AUGUR ART flaw detectors and a phased array with a frequency of 10 MHz. Due to the multi-angle voicing of the defect area, reliable detection and measurement of the damage zone is ensured.
At the same time, additional information about defects such as hydrogen cracking can also be obtained through TOFD channels, which are implemented using the above-mentioned flaw detectors.
