Tubes et tuyaux soud\u00e9s en alliage de nickel<\/h1>\n \n

\n Lorsque des projets industriels n\u00e9cessitent le transport de fluides de grand diam\u00e8tre, des conduits d'\u00e9vacuation \u00e9tendus ou des solutions d'\u00e9change de chaleur rentables, les tubes soud\u00e9s constituent le premier choix. 28Nickel fabrique des tubes en alliage de nickel soud\u00e9s de haute qualit\u00e9 \u00e0 partir de t\u00f4les et de bandes lamin\u00e9es de premi\u00e8re qualit\u00e9. Soumis \u00e0 la radiographie 100% (rayons X) et \u00e0 un contr\u00f4le de qualit\u00e9 rigoureux, nos produits soud\u00e9s garantissent que le cordon de soudure pr\u00e9sente exactement la m\u00eame r\u00e9sistance \u00e0 la corrosion et la m\u00eame r\u00e9sistance m\u00e9canique que le superalliage de base.\n <\/p>\n <\/div>\n\n

Nuances d'alliage disponibles pour les tubes et tuyaux soud\u00e9s<\/h2>\n

\n Nous fabriquons des syst\u00e8mes de tuyauterie soud\u00e9s pour tout traiter, de l'eau de mer agressive dans les usines de dessalement aux gaz de combustion tr\u00e8s acides dans les \u00e9purateurs des centrales \u00e9lectriques.\n <\/p>\n \n

Avantages techniques de la construction soud\u00e9e<\/h2>\n

\n Les technologies avanc\u00e9es de soudage en continu (telles que le GTAW\/TIG et le plasma), combin\u00e9es au traitement thermique apr\u00e8s soudage, ont permis d'am\u00e9liorer la qualit\u00e9 des produits soud\u00e9s. alliages de nickel<\/a> une alternative tr\u00e8s fiable aux tubes sans soudure.\n <\/p>\n \n

Grands diam\u00e8tres illimit\u00e9s<\/h3>\n <\/div>\n

Alors que les tubes sans soudure sont limit\u00e9s par les capacit\u00e9s des presses \u00e0 extrusion (qui plafonnent g\u00e9n\u00e9ralement \u00e0 24 pouces), les tubes soud\u00e9s peuvent \u00eatre lamin\u00e9s et fabriqu\u00e9s \u00e0 pratiquement n'importe quel diam\u00e8tre, ce qui les rend essentiels pour les grandes conduites de produits chimiques et les conduits d'\u00e9vacuation.<\/p>\n <\/div>\n\n

Efficacit\u00e9 en mati\u00e8re de co\u00fbts et de d\u00e9lais<\/h3>\n <\/div>\n

Le formage de tuyaux \u00e0 partir de t\u00f4les plates ou de bobines facilement disponibles est nettement plus rapide et plus \u00e9conomique que le per\u00e7age de billettes solides. Cela permet de r\u00e9aliser d'importantes \u00e9conomies dans le cadre de projets d'infrastructure \u00e0 grande \u00e9chelle n\u00e9cessitant des kilom\u00e8tres de tuyauterie.<\/p>\n <\/div>\n\n

100% Int\u00e9grit\u00e9 de la soudure<\/h3>\n <\/div>\n

Nos tubes soud\u00e9s sont soumis \u00e0 des essais non destructifs (END) stricts, notamment la radiographie aux rayons X 100% et les essais hydrostatiques. Le cordon de soudure est souvent travaill\u00e9 \u00e0 froid et enti\u00e8rement recuit par mise en solution pour que sa structure m\u00e9tallurgique s'harmonise parfaitement avec celle du m\u00e9tal de base.<\/p>\n <\/div>\n\n

Concentricit\u00e9 sup\u00e9rieure<\/h3>\n <\/div>\n

Parce qu'ils sont form\u00e9s \u00e0 partir de feuilles plates d'\u00e9paisseur tr\u00e8s uniforme, les tubes soud\u00e9s pr\u00e9sentent g\u00e9n\u00e9ralement une meilleure concentricit\u00e9 et une \u00e9paisseur de paroi plus constante que les tubes sans soudure, qui peuvent souffrir d'une l\u00e9g\u00e8re excentricit\u00e9 au cours de l'extrusion.<\/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

Available Alloy Grades for Welded Pipe & Tube<\\\/h2>\\n

\\n We manufacture welded piping systems to handle everything from aggressive seawater in desalination plants to highly acidic flue gases in power generation scrubbers.\\n <\\\/p>\\n \\n

Engineering Advantages of Welded Construction<\\\/h2>\\n

\\n Advanced continuous welding technologies (such as GTAW\\\/TIG and Plasma) combined with post-weld heat treatment have made welded nickel alloys a highly reliable alternative to seamless pipes.\\n <\\\/p>\\n \\n

\\n \\n
\\n
\\n
\\u2b55<\\\/div>\\n

Unlimited Large Diameters<\\\/h3>\\n <\\\/div>\\n

While seamless pipes are limited by extrusion press capacities (typically topping out around 24 inches), welded pipes can be rolled and fabricated to virtually any diameter, making them essential for large chemical mains and exhaust ducting.<\\\/p>\\n <\\\/div>\\n\\n

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

Cost & Lead Time Efficiency<\\\/h3>\\n <\\\/div>\\n

Forming pipe from readily available flat-rolled plate or coil is significantly faster and more economical than piercing solid billets. This provides major cost savings for large-scale infrastructure projects requiring miles of piping.<\\\/p>\\n <\\\/div>\\n\\n

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

100% Weld Integrity<\\\/h3>\\n <\\\/div>\\n

Our welded pipes undergo strict Non-Destructive Testing (NDT), including 100% X-Ray Radiography and Hydrostatic testing. The weld bead is often cold-worked and fully solution-annealed to perfectly blend its metallurgical structure with the parent metal.<\\\/p>\\n <\\\/div>\\n\\n

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

Superior Concentricity<\\\/h3>\\n <\\\/div>\\n

Because they are formed from flat sheets with highly uniform thickness, welded pipes generally exhibit better concentricity and more consistent wall thickness (WT) than seamless pipes, which can suffer from slight eccentricity during extrusion.<\\\/p>\\n <\\\/div>\\n\\n <\\\/div>\\n\\n

FGD & Scrubber Piping<\\\/h3>\\n <\\\/div>\\n

Large diameter welded pipes made from alloys like Hastelloy C-276 and Inconel 625 are the backbone of Flue Gas Desulfurization (FGD) systems, handling highly acidic and abrasive slurry.<\\\/p>\\n <\\\/div>\\n\\n

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

Marine & Desalination<\\\/h3>\\n <\\\/div>\\n

Long runs of welded Monel 400 piping are heavily utilized in seawater intake lines, brine heaters, and offshore platform fire water systems due to their exceptional resistance to chloride pitting.<\\\/p>\\n <\\\/div>\\n\\n

Forming pipe from readily available flat-rolled plate or coil is significantly faster and more economical than piercing solid billets. This provides major cost savings for large-scale infrastructure projects requiring miles of piping.<\\\/p>\\n <\\\/div>\\n\\n

100% Weld Integrity<\\\/h3>\\n <\\\/div>\\n

Our welded pipes undergo strict Non-Destructive Testing (NDT), including 100% X-Ray Radiography and Hydrostatic testing. The weld bead is often cold-worked and fully solution-annealed to perfectly blend its metallurgical structure with the parent metal.<\\\/p>\\n <\\\/div>\\n\\n

Superior Concentricity<\\\/h3>\\n <\\\/div>\\n

Because they are formed from flat sheets with highly uniform thickness, welded pipes generally exhibit better concentricity and more consistent wall thickness (WT) than seamless pipes, which can suffer from slight eccentricity during extrusion.<\\\/p>\\n <\\\/div>\\n\\n <\\\/div>\\n\\n

FGD & Scrubber Piping<\\\/h3>\\n <\\\/div>\\n

Large diameter welded pipes made from alloys like Hastelloy C-276 and Inconel 625 are the backbone of Flue Gas Desulfurization (FGD) systems, handling highly acidic and abrasive slurry.<\\\/p>\\n <\\\/div>\\n\\n

Marine & Desalination<\\\/h3>\\n <\\\/div>\\n

Long runs of welded Monel 400 piping are heavily utilized in seawater intake lines, brine heaters, and offshore platform fire water systems due to their exceptional resistance to chloride pitting.<\\\/p>\\n <\\\/div>\\n\\n
