Comparison of acoustic emission test / water pressure test

The great advantage of acoustic emission testing (AT) is that the required hydraulic pressure test or internal examination of pressure equipment can be replaced by AT. (see also DGÜW-V §41(3) and §42(6)).

A normal hydrostatic test has a number of disadvantages, e.g:

Long interruptions of operation for the operator
Within the scope of the design, certain system parts, e.g. supports, must be significantly overdimensioned only for the initial and recurring hydrostatic test
The residual moisture remaining in the pressure equipment after the water pressure test can cause problems during the following period of use (corrosion, HIC)
The water used for the water pressure test is contaminated afterwards

Advantages Acoustic Emission Testing (AT)

In many cases, the pressure equipment can be tested close to the operating condition, i.e. in cryogenic applications, the material is also tested in this temperature range.
The humidity caused by the hydrostatic test is avoided, as the pressure is usually applied by means of pneumatic media.
only limited accessibility of the test object is required
actively detects defects
the operating medium does not have to be emptied
no pressure test water is needed and it has to be emptied again
the supporting structures of the vessel did not have to be designed for the pressure sample water weight, which is
particularly important for large pressure air vessels
there are low overall testing costs
no bladder removal is necessary for hydraulic accumulators
