Abstract
Una transformada compleja de Fourier se realiza sobre valores medidos de espesores de pared en una pluralidad de puntos en una sección transversal de un tubo en dirección axial, siendo clasificados los tipos de desviación de espesor, se calcula el valor de desviación de espesor a partir del valor absoluto del componente complejo de Fourier, se calcula la posición de una porción gruesa y una porción delgada de desviación de espesor a partir de la fase del componente complejo de Fourier, y se ajustan las condiciones de fabricación del tubo basadas en el tipo de desviación de espesor, el valor de desviación de espesor, y la posición de la porción gruesa o de la porción delgada. La relación r*exp(jTheta)entre el valor de desviación de espesor r y la fase theta de una desviación de espesor de primer orden obtenida para una pluralidad de secciones transversales en dirección axial es sometida a una transformada compleja de Fourier como una función de dirección longitudinal del tubo, siendo luego clasificada la desviación de espesor por la frecuencia de rotación de la desviación de espesor, tomándose una acción apropiada para evitar la desviación de espesor de acuerdo con la desviación de espesor clasificada.
