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\\\/fr\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Titane contrefait : cinq

Avec plus de 15 ans d'exp\u00e9rience dans l'exportation de titane, il a appris \u00e0 examiner lui-m\u00eame chaque ligne de sp\u00e9cification, en v\u00e9rifiant la nuance, la norme, les dimensions, la tol\u00e9rance et le p\u00e9rim\u00e8tre du certificat par rapport aux capacit\u00e9s de l'usine avant d'\u00e9tablir une offre, plut\u00f4t que d'orienter les demandes vers un service commercial. Il est venu \u00e0 l'approvisionnement en titane depuis l'autre c\u00f4t\u00e9 de la transaction. Avant de diriger les activit\u00e9s internationales de Beiyu, il a travaill\u00e9 chez Koch (Koch-Glitsch) et a particip\u00e9 directement \u00e0 la r\u00e9alisation d'un projet p\u00e9trochimique SABIC dans le Fujian, en Chine. Ce travail reposait sur des plans de contr\u00f4le et d'essais, la certification des mat\u00e9riaux et la tra\u00e7abilit\u00e9 par num\u00e9ro de coul\u00e9e, la coordination du contr\u00f4le par tierce partie, ainsi que le contr\u00f4le de la documentation et des dossiers de projet. Ce sont les quatre m\u00eames \u00e9l\u00e9ments qu'un acheteur de l'industrie des proc\u00e9d\u00e9s ou un acheteur soumis \u00e0 r\u00e9glementation exigera d'un fournisseur de titane, et le fait d'avoir d\u00fb les faire appliquer en tant que client explique qu'ils soient trait\u00e9s ici comme faisant partie de la fourniture plut\u00f4t que comme des documents produits ult\u00e9rieurement. Son travail quotidien couvre les questions auxquelles ce site est destin\u00e9 \u00e0 r\u00e9pondre : choisir entre des nuances de titane commercialement pur et alli\u00e9 pour un service corrosif, lire un certificat mati\u00e8re par rapport \u00e0 la norme command\u00e9e, et faire correspondre la d\u00e9signation d'un acheteur (nuance ASTM, UNS, num\u00e9ro Werkstoff allemand ou code NF fran\u00e7ais) au m\u00eame m\u00e9tal sur diff\u00e9rents march\u00e9s.
