Abstract

UN METODO MEJORADO PARA CONECTAR UNO O MAS ANODOS METALICOS DE VALVULA NO CORROIBLES, CUYAS SUPERFICIES HAN SIDO ACTIVADAS POR UN DEPOSITO DE UN MATERIAL NO PASIVABLE CON EL NUCLEO CORROIBLE DE UN SUMINISTRADOR DE ENERGIA AISLADO, PAR PRODUCIR EL MONTAJE DE UN ANODO FLEXIBLE QUE SERA USADO PARA LA PROTECCION CATODICA DE ESTRUCTURAS METALICAS. EN EL METODO INVENTADO, UNA SERIE DE MANGUITOS METALICOS Y DUCTILES (7, 8, 9) SON COLOCADOS SOBRE UN ANODO METALICO DE VALVULA TUBULAR (6), PROVISTO CON UNA SUPERIFICIE EXTERIOR RESISTENTE A LA CORROSION. EL CABLE SUMINSTRADOR DE ENERGIA (2) PASA A TRAVES DE, POR LO MENOS, UNA PIEZA DE UNA TUBERIA ELASTOMERICA (5A, 5B), CON UN DIAMETRO INTERNO LAVEMENTE MAYOR QUE EL AISLAMIENTO DEL CABLE, Y UN DIAMETRO EXTERNO LEVEMENTE MENOR QUE EL DIAMETRO INTERNO DEL ANODO. EL CABLE Y LA TUBERIA PASAN A TRAVES DEL ANODO HASTA QUE UN SEGMENTO DEL CABLE ESTA POR DEBAJO DE UNO DE LOS MANGUITOS. PREVIAMENTE EL CABLE ES DESPOJADO DEL REVESTIMIENTO AISLANTE, Y ES PROVISTO CON UN COLLAR DIVIDIDO (4A, 4B), ALTAMENTE CONDUCTOR, CON UN ESPESOR SIMILAR AL ESPESOR COMBINADO DEL AISLANTE DEL CABLE Y DE LA TUBERIA ELASTOMERICA. AL MENOS UNA PIEZA DE LA TUBERIA ES COLOCADA EN UNO DE LOS LADOS DEL SEGMENTO DE CABLE SIN REVESTIMIENTO, POR DEBAJO DE POR LO MENOS, UNO DE LOS MANGUITOS. DESPUES DE QUE EL ANODO ES COLOCADO EN SU SITIO, SU CIRCUNFERENCIA ES REDUCIDA A LAS POSICIONES CORRESPONDIENTES A LOS MANGUITOS MEDIANTE RECALCADO EN FRIO. EL METODO INVENTADO PUEDE SER USADO PARA FORMAR UN PRECINTO ENTRE EL ANODO Y LOS CABLES AISLADOS, CON UN BAJO COSTO Y MATERIALES AISLANTES NO ELASTOMERICOS, QUIMICAMENTE RESISTENTES.
