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\\\/it\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Tubo di titanio: senza saldatura o saldato, e secondo quale norma","description":"Senza saldatura e saldato corrispondono a norme di prodotto diverse con campi dimensionali diversi, non a livelli di qualit\u00e0.

In oltre 15 anni nell'esportazione di titanio ha imparato a riesaminare personalmente ogni riga della specifica, verificando grado, norma, dimensioni, tolleranza e ambito del certificato rispetto alla capacit\u00e0 dello stabilimento produttore prima di formulare un'offerta, anzich\u00e9 inoltrare le richieste attraverso un ufficio vendite. \u00c8 arrivato alla fornitura di titanio dall'altra parte della transazione. Prima di guidare l'attivit\u00e0 internazionale di Beiyu ha lavorato presso Koch (Koch-Glitsch) ed \u00e8 stato direttamente coinvolto nella consegna di un progetto petrolchimico SABIC a Fujian, Cina. Tale lavoro si basava su piani di controllo e prova, certificazione dei materiali e tracciabilit\u00e0 tramite il numero di colata, coordinamento del collaudo di terza parte e controllo della documentazione e dei dossier di progetto. Sono le stesse quattro cose a cui un acquirente dell'industria di processo o regolamentato sottoporr\u00e0 un fornitore di titanio, e aver dovuto farle rispettare come cliente spiega perch\u00e9 qui siano trattate come parte della fornitura anzich\u00e9 come documentazione prodotta in seguito. Il suo lavoro quotidiano copre le questioni a cui questo sito intende rispondere: scegliere tra gradi di titanio commercialmente puro e legato per un servizio corrosivo, leggere un certificato del materiale rispetto alla norma ordinata e associare la designazione di un acquirente (grado ASTM, UNS, numero Werkstoff tedesco o codice NF francese) allo stesso metallo nei vari mercati. Beiyu fornisce prodotti di stabilimento in titanio, leghe di nichel e metalli refrattari in barra, tondo, lamiera spessa, tubo, blocco, anello, bobina, lingotto, pezzi forgiati e pezzi lavorati, con documentazione EN 10204 3.1 e tracciabilit\u00e0 tramite il numero di colata.","url":"https:\/\/beiyutitanium.com\/it\/author\/penn-ma\/"}]}},"_links":{"self":[{"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/posts\/5435","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/comments?post=5435"}],"version-history":[{"count":2,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/posts\/5435\/revisions"}],"predecessor-version":[{"id":5499,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/posts\/5435\/revisions\/5499"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/media\/5479"}],"wp:attachment":[{"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/media?parent=5435"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/categories?post=5435"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beiyutitanium.com\/it\/wp-json\/wp\/v2\/tags?post=5435"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
