Flansche mit geschwei\u00dftem Hals aus Nickellegierung<\/h1>\n \n

\n Wenn Rohrleitungssysteme unter extremem Druck, starken Temperaturschwankungen oder hochgef\u00e4hrlichen Medien arbeiten, muss Weld Neck Flansche<\/a> (WNRF \/ WNRTJ) sind der Industriestandard. 28Nickel stellt erstklassige geschmiedete Vorschwei\u00dfflansche aus Nickellegierung her, die sich durch eine unverwechselbare lange, konische Nabe auszeichnen, die die Spannung allm\u00e4hlich vom Flanschboden auf das Rohr \u00fcbertr\u00e4gt und so die absolute Unversehrtheit der Verbindung in den kritischsten chemischen und Offshore-Anwendungen gew\u00e4hrleistet.\n <\/p>\n <\/div>\n\n

Verf\u00fcgbare Legierungssorten f\u00fcr Vorschwei\u00dfflansche<\/h2>\n

\n Da Vorschwei\u00dfflansche direkt an das Rohr geschwei\u00dft werden, muss ihr Werkstoff perfekt auf das Rohrleitungssystem abgestimmt sein, um eine einwandfreie Schwei\u00dfnaht und eine gleichm\u00e4\u00dfige W\u00e4rmeausdehnung zu gew\u00e4hrleisten. Wir liefern diese kritischen Komponenten, die aus den robustesten Superlegierungen der Welt geschmiedet werden.\n <\/p>\n \n

Technische Vorteile von Flanschen mit geschwei\u00dftem Vorbau<\/h2>\n

\n Im Gegensatz zu Aufsteck- oder Schwei\u00dfmuffenflanschen sind Vorschwei\u00dfflansche speziell daf\u00fcr ausgelegt, starken Biegungen, Vibrationen und Temperaturschocks standzuhalten.\n <\/p>\n \n \n

\n \n
\n
\n
\ud83d\uddfc<\/div>\n

Konische Nabenkonstruktion<\/h3>\n <\/div>\n

Die lange, sich verj\u00fcngende Nabe geht allm\u00e4hlich von der Flanschdicke auf die Wanddicke des Rohrs \u00fcber. Dadurch wird die Spannungskonzentration an der Basis des Flansches drastisch reduziert und die Last auf die Rohrwand verlagert.<\/p>\n <\/div>\n\n

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

Radiographie bereit<\/h3>\n <\/div>\n

Da der Flansch mit dem Rohr durch eine einzige, voll durchgeschwei\u00dfte V-Stumpfschwei\u00dfung verbunden ist, kann die Verbindung problemlos mit dem R\u00f6ntgenpr\u00fcfger\u00e4t 100% gepr\u00fcft werden, eine wesentliche Voraussetzung f\u00fcr hochgef\u00e4hrdete Chemieleitungen.<\/p>\n <\/div>\n\n

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

Glatter interner Fluss<\/h3>\n <\/div>\n

Die Bohrung des Flansches ist genau auf den Innendurchmesser (ID) des Anschlussrohrs abgestimmt. So entsteht ein nahtloser \u00dcbergang, der Turbulenzen, Erosion und Druckabfall minimiert.<\/p>\n <\/div>\n\n

Nickel Alloy Weld Neck Flanges<\\\/h1>\\n \\n

\\n When piping systems operate under extreme pressure, severe temperature fluctuations, or highly hazardous media, Weld Neck Flanges (WNRF \\\/ WNRTJ) are the industry standard. 28Nickel manufactures premium forged nickel alloy weld neck flanges featuring a distinctive long tapered hub that gradually transfers stress from the flange base to the pipe, ensuring absolute joint integrity in the most critical chemical and offshore applications.\\n <\\\/p>\\n <\\\/div>\\n\\n

Available Alloy Grades for Weld Neck Flanges<\\\/h2>\\n

\\n Because weld neck flanges are butt-welded directly to the pipe, their material must perfectly match the piping system to ensure a flawless weld and uniform thermal expansion. We supply these critical components forged from the world's most robust superalloys.\\n <\\\/p>\\n \\n

\\n

\\n Inconel\\u00ae 625 (Excellent Pitting Resistance)<\\\/a>\\n Inconel\\u00ae 718 (High Strength\\\/Pressure)<\\\/a>\\n \\n Monel\\u00ae 400 (HF Acid & Seawater)<\\\/a>\\n Monel\\u00ae K-500 (Marine\\\/Sour Gas)<\\\/a>\\n \\n Hastelloy\\u00ae C-276 (Severe Chemical Processing)<\\\/a>\\n Waspaloy\\u00ae (Extreme High Temp Exhausts)<\\\/a>\\n <\\\/div>\\n <\\\/div>\\n\\n

Engineering Advantages of Weld Neck Flanges<\\\/h2>\\n

\\n Unlike slip-on or socket-weld flanges, weld neck flanges are engineered specifically to endure severe bending, vibration, and thermal shock.\\n <\\\/p>\\n \\n \\n

\\n \\n
\\n
\\n
\\ud83d\\uddfc<\\\/div>\\n

Tapered Hub Design<\\\/h3>\\n <\\\/div>\\n

The long tapered hub gradually transitions the thickness of the flange down to the wall thickness of the pipe. This drastically reduces stress concentration at the base of the flange, shifting the load to the pipe wall.<\\\/p>\\n <\\\/div>\\n\\n

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

Radiography Ready<\\\/h3>\\n <\\\/div>\\n

Because the flange is joined to the pipe using a single full-penetration V-bevel butt weld, the joint can easily be inspected using 100% X-ray radiography, an essential requirement for high-hazard chemical lines.<\\\/p>\\n <\\\/div>\\n\\n

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

Smooth Internal Flow<\\\/h3>\\n <\\\/div>\\n

The bore of the flange is precisely machined to match the inner diameter (ID) of the connecting pipe. This creates a seamless transition that minimizes turbulence, erosion, and pressure drop.<\\\/p>\\n <\\\/div>\\n\\n

\\n
\\n
\\u2699\\ufe0f<\\\/div>\\n

Multiple Facing Options<\\\/h3>\\n <\\\/div>\\n

Available in Raised Face (RF) for standard industrial applications, and Ring Type Joint (RTJ) for extreme pressure (Class 900# and above) where metallic ring gaskets are utilized for a perfect seal.<\\\/p>\\n <\\\/div>\\n\\n <\\\/div>\\n\\n
