Phonon Diagnostics Technique

is based on a real-time diagnostics of physics process which goes in material and structure of facilities

PHONON DIAGNOSTICS

Phonon Diagnostics Technique PDT

Phonon Diagnostics Technique allows to carry out a real-time inspection of physical processes occurring in the structure.

Distribution, level, intensity, concentration and other parameters of phonon emission determine the state of the material, characterise the technical condition of the structure.

Unlike in-line inspection, Phonon Diagnostics Technique does not imply significant costs for pipeline preparation and allows to reduce customers costs.

Phonon Diagnostics Technique is actively developing and it’s successful applied on different types of facilities including pipelines, piping, risers, pressure vessels, structures, etc.

Phonon Diagnotics Technique (PDT) includes:

Phonon desk set-up, determination of installation location of phonon emission transducers and following inspection steps.

The inspected object is divided into sections up to approx. 1 km long, in case if phonon emission transducers are installed right on the surface of inspected component.

It is possible to carry out inspection of longer areas using waveguides– concentrators of phonon emission (so-called "phonon crystals").

Phonon emission transducers are installed on cleaned object surface in pits.

The duration of the phonon monitoring of each site is usually from 1 to 4 hours depending on the geometry and operating conditions of the facility.

Phonon Diagnostics Technique Inspection Steps

During first steps

A Phonon Diagnostics mathematical model of the object is developed and so-called full-scale calibration for each area of the object are carried out .

Phonon emission active areas are image on phonon maps presented in object drawings in real-time during monitoring.

Active areas position determines the places of known defect formation, unknown defect formation, as well as indications of other character. Thus, by occurrence, position and intensity of an active area, the analysis of defect formation and spatial localisation of defects along the length of the pipeline is carried out, a phonon map is created for each inspected area.

Next step is a detailed analysis of each phonon-active area performed with the help of the Phonon software. This process determines the way of phonon emission distribution in each area. The physical processes occurring in the defective areas, dimensional characteristics, activity and severity of defects are evaluated based on the analysis results, the further development of defects is forecast.

Next steps

Phonon emission sensors should be installed on the inspected component. Data collection units should be connected to the power source. Phonon software should run. Radio synchronization system should be installed to connect PET systems, the protection of radio channels against industrial interference should be evaluated. PET and data collection units should be connected. Inspected object should be calibrated using ready-made models and unique data for each facility. Test monitoring should be performed for 30 minutes to determine the accuracy of calibration for the inspected object and the operability of phonon emission sensors in the data collection mode and the quality of the received signals in the information processing mode.

Next step is approx. 2 hours Phonon Diagnostics monitoring including collection and processing of information to assess the operation of the registration scheme. If necessary, the monitoring time can be increased.

Phonon Diagnostics Technique does not require mechanical movement of equipment on the facility surface. There are no obstacles to inspect pipeline sections with curved bends, pipes with complex geometric shapes, flanged connections, elbows, etc.

Phonon Diagnostics Technique (PDT) provides quick and hight quality of information processing, reducing of preparation and inspection terms, reducing the complexity of inspection and results processing; this contributes to the expansion of technique application areas.
