Le flange a saldare sono utilizzate per tubazioni di piccole dimensioni e ad alta pressione che non trasferiscono fluidi altamente corrosivi, in quanto questi tipi di flange sono soggetti a corrosione nell'area della fessura tra l'estremit\u00e0 del tubo e la spalla del bicchiere.<\/strong><\/p>\n

Domande frequenti (FAQ)<\/h2>\n
\nQuali sono le applicazioni ideali per le flange a bicchiere?<\/summary>\n

Le flange a saldare sono pi\u00f9 adatte per sistemi di tubazioni di piccole dimensioni e ad alta pressione che non trattano fluidi altamente corrosivi a causa della potenziale corrosione nell'area della fessura.<\/p>\n<\/details>\n

\nQual \u00e8 la resistenza statica e a fatica delle flange a bicchiere rispetto alle altre flange?<\/summary>\n

Le flange con saldatura a bicchiere offrono una resistenza statica simile a quella delle flange slip-on, ma hanno una maggiore resistenza alla fatica grazie alla singola saldatura a filetto, che ne aumenta la durata in presenza di carichi fluttuanti.<\/p>\n<\/details>\n

\nQuali sono i materiali disponibili per le flange a saldare?<\/summary>\n

Le nostre flange a saldare a bicchiere sono disponibili in una variet\u00e0 di materiali, tra cui acciai inossidabili 304, 304L, 316L e leghe ad alta resistenza come 2507 e 2205, per soddisfare le diverse esigenze applicative.<\/p>\n<\/details><\/div>","protected":false},"excerpt":{"rendered":"

\n
INTRO<\/div>\n
Le nostre flange a saldare a bicchiere offrono una soluzione affidabile e robusta per il collegamento di tubi in sistemi ad alta pressione e ad alta temperatura. <\/p>\n

Progettate per garantire una tenuta e una resistenza superiori, queste flange sono ideali per l'impiego in settori esigenti come quello petrolifero, chimico, del gas naturale e delle centrali elettriche.<\/p><\/div>\n<\/p><\/div>\n
