Abstract (en)
[origin: WO02079725A1] The invention relates to a method for ultrasound measurement of the layer thickness of thin-walled tubes. The inventive method is characterized in that a high-frequency probe (3) (more than 40 MHz) with a coupling area (4) is used that has a planar area surface. Said area surface is coupled to the tube surface (12) that is wetted with a coupling agent (8) by way of a contact method. The inventive method is used for duplex or liner layers of 0.15 mm thickness of reactor fuel cladding tubes.
