Acoustic Emission Specialists

AE Steel is a high tech start-up founded to develop acoustic emission (AT) technology. This work is a continuation of research conducted in leading European research centers: Institute of Fundamental Technological Research of the Polish Academy of Sciences, Silesian University of Technology, and Politecnico di Milano. The goal of AE Steel is to develop solutions that use AT to reduce costs associated with the operation of industrial infrastructure to the maximum and, at the same time, to reduce technical risks.


Testing pressure equipment with acoustic emission method

The main purpose of AE testing of pressure equipment is to detect, locate and evaluate EA signal sources caused by surface and internal discontinuities in walls, welds and other components of the test object. The AT reveals active AE sources generated by cracks or other material discontinuities, corrosive processes, leakages and plastic deformation.

Testing covers only the parts of the equipment that are subject to stress during the test, therefore the test can cover either the entirety of the equipment or only its part. The scope of the AT examination is being determined each time based on the analysis of the equipment’s structure.

AE testing of above-ground vertical steel storage tank floor

AE Steel performs tests in accordance with the developed procedure for the floors of above-ground vertical steel storage tanks to detect and classify EA signal sources derived from active corrosion, material discontinuities or leaks.

As with any AT application, the acquired data only contain the information about active sources. Testing reveals active corrosive processes, such as general and localized corrosion (as defined in the norm PN-EN ISO 8044:2015-12), leading to a gradual loss of wall thickness, active discontinuities or leakages. The detected AE sources are evaluated, which leads to the classification of the technical condition of the floor of the tested tank and to recommendations regarding further operation of the vessel.

Diagnostics of oil energy transformers with the on-line acoustic emission method

The fundamental reason for the accelerated degradation of transformer oil are partial discharges. Its evaluation is possible with three methods:

  • electric – not used during normal operations
  • gas chromatography – sensitive to measurement errors
  • acoustic emission – relatively insensitive to interference, simple and the cheapest one.

Partial discharge detection with acoustic emissions is used with success during their normal operation. Locating internal transformer malfunction enables decreasing the cost of repair. It enables the analysis of the development of internal malfunctions and to make justified decisions about their further operation. As a result, it is possible to plan repairs, which prevents potential malfunctions. This is the simplest and cheapest of the available methods of partial discharge monitoring.

Acoustic emission testing (AT) is one of the most important Non-destructive testing (NDT) methods. Testing consists of recording and analyzing elastic waves generated during the development of existing damages or the appearance of new ones.

AT is a method which enables detection and location of developing deformation processes in the early stages of damage – before it becomes dangerous. Advanced analysis enables classifying the objects by their technical state and the estimated time of their safe operation.

It is important that the diagnostics can be run without interrupting the operation, which renders significant savings. In practice, in many cases, acoustic emission is a much cheaper method of diagnostics than the traditional ones, based on internal revision.

Main areas of AT application:

- pipelines
- pressure vessels
- storage tanks
- engineering objects
- aerospace industry
- transformers.

Acoustic emission testing advantages:

  • Acknowledged by the Office of Technical Supervision
  • Enables shortening the time of inspection – rendering significant savings
  • Enables detecting all kinds of active defects during the test, while most methods concentrate only on select few types of defects
  • Does not require long-term shutdown of the device’s operation - up to 36 hours in the worst-case scenario
  • It allows for a comprehensive analysis of the object, i.e. detection and location of damages within the structure, regardless of their visibility or their location relative to the installed sensors. Simultaneously with the detection of the damage, the intensity of emission signalizes the level of risk that the defect poses to the structure
  • Enables prolonging the time of operation of the structure
  • Increases the safety of the structure
  • Enables locating the damages
