Abstract

EL TUBO DOBLE (1) COMPRENDE UN ALMA TUBULAR (2) Y UNA CAPA DE FORRADO O DE REVESTIMIENTO (3) DE UNA ALEACION CUYO METAL BASICO ES IDENTICO AL METAL BASICO DE LA ALEACION QUE CONSTITUYE EL ALMA TUBULAR (2). SE EMITEN ONDAS ULTRASONICAS EN INCIDENCIA NORMAL EN EL ESPESOR DEL REVESTIMIENTO (3) Y DEL ALMA (2) DEL TUBO (1), SE RECOGEN LAS ONDAS ULTRASONICAS REFLEJADAS POR LAS SUPERFICIES INTERNA Y EXTERNA DEL TUBO, POR SU SUPERFICIE DE CONTACTO (4) Y POR DEFECTOS DE COHESION EVENTUALES DE LA SUPERFICIE DE CONTACTO (4), SE MIDEN LOS TIEMPOS DE PROPAGACION DE LAS ONDAS ULTRASONICAS EN EL ESPESOR DEL TUBO, SE DETERMINA LA AMPLITUD Y LA FORMA DE LAS ONDAS REFLEJADAS SE SOMETE EL TUBO (1), DESDE SU SUPERFICIE EXTERNA, A UNA INDUCCION MAGNETICA CREADA POR UNA CORRIENTE SINUSOIDAL DE MULTIFRECUENCIA, SE EFECTUAN MEDIDAS DE FASE Y/O DE AMPLITUD DE LAS CORRIENTES INDUCIDAS EN EL TUBO (1), SE DEDUCE EL ESPESOR DE LA CAPA DE REVESTIMIENTO (3), SE CALCULA EL ESPESOR TOTAL DEL TUBO (1) A PARTIR DE LAS MEDIDAS DE TIEMPO DE PROPAGACION DE LOS ULTRASONIDOS Y DEL ESPESOR DE LA CAPA DE REVESTIMIENTO (3), Y SE DETERMINA LA COHESION DEL TUBO EN SU SUPERFICIE DE CONTACTO (4) POR ANALISIS DE LA AMPLITUD Y DE LA FORMA DE LAS ONDAS ULTRASONICAS REFLEJADAS POR LA SUPERFICIE DE CONTACTO (4) O TRANSMITIDAS POR LA CAPA DE REVESTIMIENTO (3).
