Abstract

LA INVENCION SE REFIERE A UN TUBO RESISTENTE A LA CORROSION A BASE DE UNA ALEACION DE COBRE, QUE ESTA PROTEGIDO POR MEDIO AL MENOS DE UNA CAPA DE OXIDO. PARA LA REDUCCION DE LA NEGLIGENCIA DE COBRE DEL TUBO A TRAVES DE LA FORMACION DE LA CAPA DE OXIDO ESPECIAL, SE PROPONE DE ACUERDO CON LA INVENCION QUE EL TUBO PROPUESTO DE UNA ALEACION DE COBRE CON 0,01 HASTA 1 % DE UN ELEMENTO ALEADO A BASE DEL GRUPO DE ALUMINIO, ESTAÑO, ZINC O SILICIO, MUESTRE UNA CAPA DE OXIDO INTERNA QUE SE ENCUENTRA EN EL INTERIOR DE LA SUPERFICIE TUBULAR EXTERIOR, COMPUESTA EXCLUSIVAMENTE A BASE DEL OXIDO DEL ELEMENTO AÑADIDO EN LA ALEACION.
