Abstract

Procedimiento para el ensayo no destructivo de tubos de material magnetizable con respecto a fallas por medio de flujo de dispersion, en el cual el tubo que se mueve en direccion longitudinal y que además gira opcionalmente. es magnetizado y explorado en forma helicoidal, el flujo magnético producido es transferido sin contacto al tubo y las irregularidades que se encuentran en la zona cercana a la superficie producen flujos de dispersion magnéticos, las cuales salen de la superficie del tubo y son detectados mediante sensores y son transformados aproximadamente en tiempo real en senales eléctricas que se pueden evaluar, con los siguientes pasos, transferencia de las senales en un preamplificador, traslado de las senales analogicas en una corriente de datos continua de datos digitales, almacenamiento intermedio de la corriente de datos en una primera memoria (A), llenado de la primera memoria (A) con k puntos de datos, copiado de los k puntos de datos de la primera memoria (A) en una segunda memoria (B) en el intervalo de un corto tiempo entre dos puntos de datos digitales y nuevo llenado simultáneo de la primera memoria (A) con nuevos datos, transformacion de los datos copiados por medio de la transformada wavelet y filtrado y/o modificacion de los coeficientes wavelet resultantes, comparacion de la medida de evaluacion con una medida de referencia, en donde una senal de falla obtenida de la posicion de la falla puede ser asignada claramente.
