Abstract

UN DISPOSITIVO PARA EL ENSANCHAMIENTO HIDRAULICO DE SEGMENTOS TUBULARES, PREFERENTEMENTE DE EXTREMOS DE TUBO, POR MEDIO DE UNA SONDA CILINDRICA INSERTABLE EN EL TUBO. LA SONDA CONSTITUYE POR MEDIO DE AL MENOS DOS ANILLOS DE JUNTA, CON EL SEGMENTO TUBULAR A SER ENSANCHADO, UN RECINTO ANULAR, QUE SE LLENA CON MEDIO DE PRESION PARA EL ENSANCHADO. LOS DOS ANILLOS DE JUNTA ESTAN DISPUESTOS RESPECTIVAMENTE EN UNA ESCOTADURA DE ALOJAMIENTO ANULAR DE LA SONDA, QUE TIENE EN ESTADO INICIAL UN DIAMETRO EXTERNO QUE CORRESPONDE COMO MAXIMO AL DIAMETRO EXTERNO DE LA SONDA Y SE ENSANCHAN ANTES DEL COMIENZO DEL PROCESO DE ENSANCHAMIENTO. EL MEDIO DE PRESION SE ENVIA A LAS ACANALADURAS DE ALOJAMIENTO POR MEDIO DE UN CONDUCTO DE COMUNICACION CONECTADO CON LA ALIMENTACION DEL MEDIO DE PRESION. ANTES DEL COMIENZO DEL PROCESO DE ENSANCHAMIENTO SE OBTIENE UN EFECTO DE EMPAQUETADURA FIABLE DE LOS ANILLOS DE JUNTA, PARA LO CUAL SE EFECTUA LA ALIMENTACION DEL MEDIO DE PRESION HASTA EL RECINTO ANULAR EXCLUSIVAMENTEA TRAVES, AL MENOS DE UNA DE LAS ACANALADURAS DE ALOJAMIENTO DE EMPAQUETADURA POR ENSANCHAMIENTO ELASTICO.
