Geschwei\u00dfte Rohre aus Nickellegierungen<\/h1>\n \n

\n Wenn Industrieprojekte den Transport von Fl\u00fcssigkeiten mit gro\u00dfem Durchmesser, umfangreiche Abluftkan\u00e4le oder kosteneffiziente L\u00f6sungen f\u00fcr den W\u00e4rmeaustausch erfordern, sind geschwei\u00dfte Rohre die erste Wahl. 28Nickel stellt hochwertige geschwei\u00dfte Rohre aus Nickellegierungen aus erstklassigen gewalzten Platten und B\u00e4ndern her. Unsere geschwei\u00dften Produkte werden einer 100%-Radiographie (R\u00f6ntgen) und strengen Qualit\u00e4tskontrollen unterzogen, um sicherzustellen, dass die Schwei\u00dfnaht die gleiche Korrosionsbest\u00e4ndigkeit und mechanische Festigkeit aufweist wie die Basis-Superlegierung.\n <\/p>\n <\/div>\n\n

Verf\u00fcgbare Legierungssorten f\u00fcr geschwei\u00dfte Rohre und Schl\u00e4uche<\/h2>\n

\n Wir stellen geschwei\u00dfte Rohrleitungssysteme her, die f\u00fcr alles geeignet sind, vom aggressiven Meerwasser in Entsalzungsanlagen bis hin zu stark sauren Rauchgasen in W\u00e4schern der Energieerzeugung.\n <\/p>\n \n

Technische Vorteile der geschwei\u00dften Konstruktion<\/h2>\n

\n Fortschrittliche kontinuierliche Schwei\u00dftechniken (wie WIG\/TAG und Plasma) in Verbindung mit einer W\u00e4rmebehandlung nach dem Schwei\u00dfen haben dazu gef\u00fchrt, dass geschwei\u00dfte Nickellegierungen<\/a> eine \u00e4u\u00dferst zuverl\u00e4ssige Alternative zu nahtlosen Rohren.\n <\/p>\n \n

Unbegrenzt gro\u00dfe Durchmesser<\/h3>\n <\/div>\n

W\u00e4hrend nahtlose Rohre durch die Kapazit\u00e4ten der Strangpressen begrenzt sind (in der Regel liegt die Obergrenze bei 24 Zoll), k\u00f6nnen geschwei\u00dfte Rohre auf praktisch jeden Durchmesser gewalzt und hergestellt werden, was sie f\u00fcr gro\u00dfe Chemieleitungen und Abgaskan\u00e4le unverzichtbar macht.<\/p>\n <\/div>\n\n

Kosten- und Vorlaufzeit-Effizienz<\/h3>\n <\/div>\n

Das Formen von Rohren aus leicht verf\u00fcgbaren flachgewalzten Blechen oder Coils ist wesentlich schneller und wirtschaftlicher als das Lochen von massiven Kn\u00fcppeln. Dies erm\u00f6glicht erhebliche Kosteneinsparungen bei gro\u00dfen Infrastrukturprojekten, die kilometerlange Rohrleitungen erfordern.<\/p>\n <\/div>\n\n

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

100% Integrit\u00e4t der Schwei\u00dfnaht<\/h3>\n <\/div>\n

Unsere geschwei\u00dften Rohre werden einer strengen zerst\u00f6rungsfreien Pr\u00fcfung (NDT) unterzogen, einschlie\u00dflich 100%-R\u00f6ntgenaufnahme und hydrostatischer Pr\u00fcfung. Die Schwei\u00dfraupe wird h\u00e4ufig kaltverformt und vollst\u00e4ndig l\u00f6sungsgegl\u00fcht, um ihre metallurgische Struktur perfekt mit dem Grundwerkstoff zu verbinden.<\/p>\n <\/div>\n\n

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

Hervorragende Konzentrationsf\u00e4higkeit<\/h3>\n <\/div>\n

Da sie aus flachen Blechen mit sehr gleichm\u00e4\u00dfiger Dicke geformt werden, weisen geschwei\u00dfte Rohre im Allgemeinen eine bessere Rundlaufgenauigkeit und eine gleichm\u00e4\u00dfigere Wanddicke (WT) auf als nahtlose Rohre, bei denen es w\u00e4hrend der Extrusion zu leichten Exzentrizit\u00e4ten kommen kann.<\/p>\n <\/div>\n\n <\/div>\n\n

Geschwei\u00dfte Rohre mit gro\u00dfem Durchmesser, hergestellt aus Legierungen wie Hastelloy C-276<\/a> und Inconel 625<\/a> sind das R\u00fcckgrat von Rauchgasentschwefelungsanlagen (REA), die mit stark sauren und abrasiven Schl\u00e4mmen arbeiten.<\/p>\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

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

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

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
