Metoda nedestruktivního měření tloušťky tenkostěnných trubek malého průměru spočívá v tom, že ke zjištění tloušťky stěny trubky využívá rezonanční frekvence kmitání v rovině příčného řezu trubky. Vzájemný poměr naměřených frekvencí velmi přesně určí tloušťku tenkostěnné trubky. Method for non-destructive thickness measurement of small diameter thin-walled pipes The method of non-destructive thickness measurement of small-diameter thin-walled pipes consists in using the resonant frequency of vibrations in the plane of the pipe cross- section to determine the pipe wall thickness. The relative ratio of the measured frequencies determines the thickness of the thin-walled pipe with great accuracy. For small pipe diameters, the method achieves the most accurate results. The accuracy of the measurement is directly dependent on the thickness of the pipe wall and for very thin walls the method achieves the highest accuracy.
