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 traceability.\",\"url\":\"https:\\\/\\\/beiyutitanium.com\\\/es\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Secci\u00f3n de barra de titanio: redonda, cuadrada, plana o hexagonal","description":"Cada secci\u00f3n de barra tiene su propio rango dimensional y sus propias cuestiones de tolerancia.

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\/5459","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=5459"}],"version-history":[{"count":3,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/posts\/5459\/revisions"}],"predecessor-version":[{"id":5600,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/posts\/5459\/revisions\/5600"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/media\/5478"}],"wp:attachment":[{"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/media?parent=5459"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/categories?post=5459"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beiyutitanium.com\/es\/wp-json\/wp\/v2\/tags?post=5459"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
