Los \u00e1nodos de titanio para protecci\u00f3n cat\u00f3dica por corriente impresa (ICCP) son electrodos de titanio recubiertos de MMO que suministran corriente protectora a una estructura enterrada o sumergida sin disolverse. Han sustituido en gran medida a los \u00e1nodos consumibles en ICCP porque el sustrato de titanio es dimensionalmente estable y de larga duraci\u00f3n. Esta gu\u00eda abarca la elecci\u00f3n del recubrimiento seg\u00fan el entorno, las formas utilizadas y qu\u00e9 indicar en una consulta.<\/p>\n

Elecci\u00f3n del recubrimiento seg\u00fan el entorno<\/h2>\n

El recubrimiento se adapta al nivel de cloruro del entorno. Se utiliza un recubrimiento de \u00f3xido de iridio-tantalio en suelo, agua dulce y hormig\u00f3n, donde el cloruro es bajo o est\u00e1 ausente y la reacci\u00f3n es de evoluci\u00f3n de ox\u00edgeno. Se utiliza un recubrimiento de \u00f3xido de rutenio-iridio en agua de mar, agua salobre y lodo, donde hay cloruro y la reacci\u00f3n es de evoluci\u00f3n de cloro.<\/p>\n\n\n\n\n\n
El recubrimiento se ajusta al nivel de cloruros del entorno.<\/caption>\n

Formas<\/h2>\n

Los \u00e1nodos de titanio para ICCP se suministran como alambre y cinta para aplicaciones de hormig\u00f3n y dep\u00f3sitos, como varillas y \u00e1nodos tubulares para lechos an\u00f3dicos y dep\u00f3sitos de agua, como malla y malla de cinta para hormig\u00f3n armado, y como \u00e1nodos de disco y de sonda.

Acerca del autor<\/h2>\n

Penn Ma<\/strong> dirige el negocio internacional de Beiyu Titanium y responde personalmente a sus solicitudes de oferta, comprobando la calidad, la norma, las dimensiones, la tolerancia y el alcance del certificado frente a la capacidad de la f\u00e1brica antes de comunicar un precio. Cuenta con 15 a\u00f1os de experiencia en la exportaci\u00f3n de titanio, con barras, varillas, chapas gruesas, tubos, bloques, anillos, bobinas, lingotes, piezas forjadas y piezas mecanizadas, y utiliza a diario documentaci\u00f3n EN 10204 3.1 y trazabilidad por n\u00famero de colada. Antes de Beiyu trabaj\u00f3 en Koch (Koch-Glitsch) y particip\u00f3 directamente en la ejecuci\u00f3n de un proyecto petroqu\u00edmico de SABIC en Fujian, China, de donde proceden las pr\u00e1cticas del comprador que sustentan este sitio: planes de inspecci\u00f3n y ensayo, certificaci\u00f3n de materiales y trazabilidad por n\u00famero de colada, coordinaci\u00f3n de la inspecci\u00f3n por tercera parte y control de expedientes de proyecto.

La base de dise\u00f1o que sustenta una cifra de vida \u00fatil de un \u00e1nodo de protecci\u00f3n cat\u00f3dica<\/h2>\n

La secci\u00f3n anterior solicita la corriente de salida requerida y la vida \u00fatil de dise\u00f1o porque esos dos campos dimensionan el \u00e1nodo. El sistema de recubrimiento se dise\u00f1a con esos criterios, para que pueda comprobarse una consulta antes de enviarla, en lugar de hacerlo despu\u00e9s de recibir una oferta.<\/p>\n

Estas son cifras de dise\u00f1o del sistema de recubrimiento de \u00f3xidos met\u00e1licos mixtos a la densidad de corriente indicada, no una garant\u00eda para un pedido concreto.<\/p>\n\n\n\n\n\n\n\n\n\n

La vida \u00fatil real depende del electrolito, el ciclo de trabajo, la densidad de corriente instalada y el relleno o la construcci\u00f3n del lecho, por lo que la corriente de salida requerida y la vida de dise\u00f1o se especifican de nuevo en cada pedido en lugar de trasladarse de un proyecto anterior.<\/p>\n

Dos cifras sustentan esas condiciones. La resistividad del recubrimiento es de alrededor de 10-7<\/sup> ohm metros. Cuando el recubrimiento est\u00e1 da\u00f1ado, el titanio expuesto se encuentra a un potencial que normalmente no supera los 2 voltios, por debajo del nivel al que se romper\u00eda la pel\u00edcula pasiva, por lo que la zona descubierta no se convierte en un punto de corrosi\u00f3n. En las instalaciones en suelo, la tensi\u00f3n de alimentaci\u00f3n suele mantenerse por debajo de 60 voltios.<\/p>\n

Beiyu Titanium revisa la estructura y el entorno, la corriente de salida requerida y la vida de dise\u00f1o, el tipo de recubrimiento, la forma y las dimensiones del \u00e1nodo y el alcance del certificado antes de presentar una oferta.<\/p>\n

Una propiedad subyace a todo esto: el sustrato conduce corriente con aproximadamente un tres por ciento de la conductividad del cobre, por lo que el detalle de la conexi\u00f3n y la secci\u00f3n importan junto con la elecci\u00f3n del recubrimiento. \u00bfEs conductor el titanio?<\/a> presenta las cifras de resistividad por calidad.<\/p>\n

Detalles de especificaci\u00f3n con fuentes<\/h2>\n

ASTM B338<\/a> y B348 cubren los sustratos tubulares y de varilla sobre los que se construyen los \u00e1nodos ICCP, en Grade 1 (UNS R50250) y Grade 2 (UNS R50400), con Grade 2 aportando una resistencia m\u00ednima a la tracci\u00f3n de 345 MPa cuando la cadena de \u00e1nodos tambi\u00e9n cumple una funci\u00f3n estructural. Los documentos de dise\u00f1o, como ISO 12696 para hormig\u00f3n, tratan el \u00e1nodo como un componente dimensionado seg\u00fan la corriente suministrada y la vida \u00fatil de dise\u00f1o, lo que coincide con el criterio de recubrimiento anterior: \u00f3xido de iridio-t\u00e1ntalo para suelos con bajo contenido de cloruros, agua dulce y hormig\u00f3n, frente a \u00f3xido de rutenio-iridio para servicio en agua de mar y agua salobre.<\/p>\n

Beiyu Titanium supplies the uncoated substrate behind these anode forms: seamless titanium tube from 5 to 325 mm OD in walls of 0.5 to 12 mm for tubular and rod anodes, with Grade 1 or Grade 2 flat product for ribbon and mesh stock, each released with an EN 10204 3.1 certificate. The MMO coating sits outside Beiyu’s mill scope and is specified per order to the environment, and in Penn Ma’s 15 years of RFQ review at Beiyu the coating type, required current output and design life are restated as three separate lines before an anode order releases, because those three fields, not the titanium, set the anode’s service life.<\/p>\n

Over 15 years in titanium export he has learned to review each specification line himself, checking grade, standard, dimensions, tolerance and certificate scope against mill capability before quoting, rather than routing enquiries through a sales desk. He came to titanium supply from the other side of the transaction. Before leading Beiyu's international business he worked at Koch (Koch-Glitsch) and was directly involved in delivering a SABIC petrochemical project in Fujian, China. That work was built on inspection and test plans, material certification and heat traceability, third party inspection coordination, and project documentation and dossier control. Those are the same four things a process industry or regulated buyer will hold a titanium supplier to, and having had to enforce them as a customer is why they are treated here as part of the supply rather than as paperwork produced afterwards. His day-to-day work spans the questions this site is written to answer: choosing between commercially pure and alloyed titanium grades for a corrosive service, reading a mill test certificate against the ordered standard, and matching a buyer's designation (ASTM grade, UNS, German Werkstoff number or French NF code) to the same metal across markets. Beiyu supplies titanium, nickel-alloy and refractory mill products across bar, rod, plate, tube, block, ring, coil, ingot, forgings and machined parts, with EN 10204 3.1 documentation and heat-number

Durante m\u00e1s de 15 a\u00f1os de exportaci\u00f3n de titanio, ha aprendido a revisar personalmente cada l\u00ednea de especificaci\u00f3n, comprobando calidad, norma, dimensiones, tolerancia y alcance del certificado frente a la capacidad de la f\u00e1brica antes de emitir una oferta, en lugar de canalizar las consultas a trav\u00e9s de un departamento comercial. Lleg\u00f3 al suministro de titanio desde el otro lado de la transacci\u00f3n. Antes de dirigir el negocio internacional de Beiyu, trabaj\u00f3 en Koch (Koch-Glitsch) y particip\u00f3 directamente en la entrega de un proyecto petroqu\u00edmico de SABIC en Fujian, China. Ese trabajo se basaba en planes de inspecci\u00f3n y ensayo, certificaci\u00f3n de materiales y trazabilidad por n\u00famero de colada, coordinaci\u00f3n de inspecci\u00f3n por tercera parte y control de la documentaci\u00f3n y los expedientes del proyecto. Esas son las mismas cuatro cosas que un comprador de la industria de procesos o regulada exigir\u00e1 a un proveedor de titanio, y haber tenido que aplicarlas como cliente es la raz\u00f3n por la que aqu\u00ed se tratan como parte del suministro y no como documentaci\u00f3n elaborada posteriormente. Su trabajo diario abarca las cuestiones que este sitio est\u00e1 concebido para responder: elegir entre calidades de titanio comercialmente puro y aleado para un servicio corrosivo, interpretar un certificado de materiales frente a la norma solicitada y relacionar la designaci\u00f3n de un comprador (calidad ASTM, UNS, n\u00famero Werkstoff alem\u00e1n o c\u00f3digo NF franc\u00e9s) con el mismo metal en distintos mercados. Beiyu suministra productos de f\u00e1brica de titanio, aleaciones de n\u00edquel y materiales refractarios en barra, varilla, chapa gruesa, tubo, bloque, anillo, bobina, lingote, piezas forjadas y piezas mecanizadas, con documentaci\u00f3n EN 10204 3.1 y trazabilidad por n\u00famero de colada.","url":"https:\/\/beiyutitanium.com\/es\/author\/penn-ma\/"}]}},"_links":{"self":[{"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/posts\/4529","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/comments?post=4529"}],"version-history":[{"count":7,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/posts\/4529\/revisions"}],"predecessor-version":[{"id":6258,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/posts\/4529\/revisions\/6258"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/media\/4755"}],"wp:attachment":[{"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/media?parent=4529"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/categories?post=4529"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/tags?post=4529"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
