Definitions
- the invention relates to a method for ultrasound measurement 7 of partial layer thicknesses on thin-walled tubes.
- Pipes of this type are, for example, cladding tubes of nuclear fuels, which 9 have a wall thickness of 1 mm and less. On the outside or inside, such pipes are often with a duplex or
- liner layer 12 Provides liner layer.
- the thickness of liner layer 12 is often only 0.15 mm and less. 13
- the object of the invention is to provide an ultrasound method.
- 32 pelflache is a narrow rectangle.
- the received echo signals have a reduced intensity
- Ratio can be determined by using digital recording
- processing and processing methods e.g. by overlaying echo pulse sequences.
- Fig.2 shows a detail from Fig.l that the cladding tube and an is probe is enlarged.
- Fig.l shows an apparatus for a method for ultra
- 22 tube 1 has a diameter of 10 mm and a wall thickness
- the cladding tube is e.g. outside with a
- Liner layer 2 provided.
- the oscilloscope 6 is a DV system, for example a PC 7
- test head 3 is coupled to the pipe surface using contact technology, the pipe surface being wetted with a conventional coupling medium, for example water, oil or glycerin.
- a conventional coupling medium for example water, oil or glycerin.
- the evaluable sound bundle 10 is limited to a narrow area, which is predetermined by the contact surface 11 between the pipe surface 12 and the coupling surface 4.
- the gap spaces 14 adjoining the contact surface 11 on both sides are also at least to a certain extent filled with coupling medium 8, which for practical reasons can hardly be avoided. These gaps generally produce disruptive echo signals that can affect the layer thickness measurement. These disturbances are strongly damped by the selected geometry of a flat coupling surface 4. An ultrasound beam 15 irradiated outside the contact surface 11 is not reflected back to its starting point due to the pipe bend 12. The long-lasting "ringing" that is known in plane-parallel columns does not occur. However, this negative effect can occur with test heads with a contact surface that is adapted to the pipe curvature.
- a sound wave 13 radiated from the coupling surface 4 outside the contact surface 11 and widened by the relatively long coupling medium path in the gap spaces 14 and is therefore not suitable for the measurement task is caused by the flat coupling surface 4 and the curved one
- Pipe surface 12 of the given geometry is deflected radially outwards, so it does not generate an echo signal which interferes with the measurement result.
- the coupling medium does not interfere with the sound coupling, since here there is practically only direct material contact and the coupling medium essentially only fills the microscopic cavities given by the roughness of the surfaces in contact with one another. However, these cavities do not interfere with the sound coupling, since they have dimensions that are far below a wavelength of the HF ultrasound.
- the method can of course also be used to measure the entire tube wall thickness. Furthermore, the layer thicknesses of multi-layered pipes can of course also be measured using the proposed method.
- the received echoes are correspondingly weak.
- the electronic noise can be filtered out by homologously superimposing several ultrasound shots.
- interference signals caused by incomplete damping of the test head or by transverse waves can also be suppressed or at least reduced with the aid of the technology mentioned, as a result of which the signal / interference ratio can be improved.
