Tubi e tubi saldati in lega di nichel<\/h1>\n \n

\n Quando i progetti industriali richiedono il trasporto di fluidi di grande diametro, condotti di scarico estesi o soluzioni di scambio termico convenienti, i tubolari saldati sono la scelta principale. 28Nickel produce tubi saldati in lega di nichel di alta qualit\u00e0 a partire da lamiere e nastri laminati di prima scelta. Sottoposti a radiografia (X-Ray) 100% e a severi controlli di qualit\u00e0, i nostri prodotti saldati garantiscono che il cordone di saldatura abbia la stessa resistenza alla corrosione e la stessa forza meccanica della superlega di base.\n <\/p>\n <\/div>\n\n

Gradi di lega disponibili per i tubi saldati<\/h2>\n

\n Produciamo sistemi di tubazioni saldate per gestire qualsiasi cosa, dall'acqua di mare aggressiva negli impianti di desalinizzazione ai gas di scarico altamente acidi negli scrubber per la produzione di energia.\n <\/p>\n \n

\n Inconel\u00ae 625 (FGD e sistemi di scarico)<\/a>\n Inconel\u00ae 718 (lavorazioni ad alta resistenza)<\/a>\n \n Monel\u00ae 400 (tubi marini e per desalinizzazione)<\/a>\n \n Hastelloy\u00ae C-276 (prodotti chimici e depuratori severi)<\/a>\n Waspaloy\u00ae (involucri aerospaziali)<\/a>\n <\/div>\n <\/div>\n\n

Vantaggi ingegneristici della costruzione saldata<\/h2>\n

\n Le tecnologie avanzate di saldatura continua (come GTAW\/TIG e Plasma), combinate con il trattamento termico post-saldatura, hanno reso le saldature leghe di nichel<\/a> un'alternativa altamente affidabile ai tubi senza saldatura.\n <\/p>\n \n

\n \n

Grandi diametri illimitati<\/h3>\n <\/div>\n

Mentre i tubi senza saldatura sono limitati dalle capacit\u00e0 delle presse di estrusione (che in genere si aggirano intorno ai 24 pollici), i tubi saldati possono essere laminati e fabbricati praticamente con qualsiasi diametro, il che li rende essenziali per le grandi condutture chimiche e i condotti di scarico.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udcc9<\/div>\n

Efficienza dei costi e dei tempi di consegna<\/h3>\n <\/div>\n

La formatura di tubi da lamiere o rotoli facilmente reperibili \u00e8 molto pi\u00f9 rapida ed economica rispetto alla perforazione di billette solide. Ci\u00f2 consente di risparmiare sui costi per progetti infrastrutturali su larga scala che richiedono chilometri di tubazioni.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udd0d<\/div>\n

100% Integrit\u00e0 della saldatura<\/h3>\n <\/div>\n

I nostri tubi saldati sono sottoposti a rigorosi controlli non distruttivi (NDT), tra cui la radiografia a raggi X 100% e i test idrostatici. Il cordone di saldatura \u00e8 spesso lavorato a freddo e completamente ricotto per fondere perfettamente la sua struttura metallurgica con il metallo madre.<\/p>\n <\/div>\n\n

\n
\n
\ud83d\udccf<\/div>\n

Concentricit\u00e0 superiore<\/h3>\n <\/div>\n

Essendo formati da lastre piane con spessore altamente uniforme, i tubi saldati presentano generalmente una migliore concentricit\u00e0 e uno spessore di parete (WT) pi\u00f9 costante rispetto ai tubi senza saldatura, che possono soffrire di una leggera eccentricit\u00e0 durante l'estrusione.<\/p>\n <\/div>\n\n <\/div>\n\n

Tubazioni FGD e scrubber<\/h3>\n <\/div>\n

Tubi saldati di grande diametro realizzati in leghe come Hastelloy C-276<\/a> e Inconel 625<\/a> sono la spina dorsale dei sistemi di desolforazione dei gas di scarico (FGD) e trattano fanghi altamente acidi e abrasivi.<\/p>\n <\/div>\n\n

\n
\n
\ud83c\udf0a<\/div>\n

Marino e desalinizzazione<\/h3>\n <\/div>\n

I lunghi tratti di tubazioni saldate in Monel 400 sono molto utilizzati nelle linee di aspirazione dell'acqua di mare, nei riscaldatori di salamoia e nei sistemi antincendio delle piattaforme offshore, grazie alla loro eccezionale resistenza alla vaiolatura da cloruri.<\/p>\n <\/div>\n\n

\n
\n
\u2668\ufe0f<\/div>\n

Tubi per condensatori saldati<\/h3>\n <\/div>\n

I tubi saldati ad alta precisione con riduzione del cordone rappresentano una soluzione economica per gli scambiatori di calore e i condensatori industriali di grandi dimensioni che richiedono migliaia di tubi a parete sottile.<\/p>\n <\/div>\n\n <\/div>\n\n

Nickel Alloy Welded Pipe & Tube<\\\/h1>\\n \\n

\\n When industrial projects require large-diameter fluid transport, extensive exhaust ducting, or cost-effective heat exchange solutions, welded tubulars are the premier choice. 28Nickel manufactures high-quality welded nickel alloy pipes and tubes from premium rolled plate and strip. Subjected to 100% radiography (X-Ray) and severe quality control, our welded products ensure the weld seam performs with the exact same corrosion resistance and mechanical strength as the base superalloy.\\n <\\\/p>\\n <\\\/div>\\n\\n
