UNS N08825 Inconel 825 Socket Weld Swrf Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N08825 Inconel 825 Socket Weld Swrf Flanges in Mumbai.
UNS N08825, better known as Inconel® 825 (often called Alloy 825), is a nickel-iron-chromium alloy augmented with molybdenum and copper, giving it excellent corrosion resistance in a wide variety of aggressive environments, including reducing acids, seawater, chloride-bearing organic compounds, and high-temperature gaseous media. When manufactured as socket weld SWRF (spigot weld / raised face) flanges, Alloy 825 combines the material’s chemical durability with the compact, mechanically robust socket-weld joint — making it a strong choice in chemical, petrochemical, offshore, and marine applications.
At Synergy Engineering Solution, we produce, stock, and export UNS N08825 socket weld SWRF flanges under rigorous quality control and process discipline. From certified Alloy 825 bar or forging stock, we perform forging, heat treatment, machining, and inspection in-house. We ensure full traceability through mill test certificates (MTCs) and support additional examinations such as PMI chemical verification, dye-penetrant or magnetic particle testing, ultrasonic testing, and third-party inspection if required. Every flange is machined to tight tolerances to guarantee accurate socket fit and raised face sealing.
Because socket weld joints require precise machining and fit-up, our CNC equipment ensures concentricity, bore tolerances, spigot depth, and face flatness to customer drawings or standard dimensions. The SWRF raised face improves gasket seating, while the socket weld design helps minimize stress concentration at the weld fillet, making the flange-weld interface more robust under thermal cycling, vibration, or mechanical loads. These attributes are especially useful in upstream, midstream, or offshore piping systems handling corrosive fluids or acids.
To support quick-turn delivery, Synergy maintains inventories of commonly requested sizes and pressure classes of Alloy 825 socket weld SWRF flanges, reducing lead times for many standard orders. For non-standard or project-specific requirements (unusual diameters, custom bore profiles, special wall thickness, or exotic finish requirements), we accept tailored orders with detailed customer specifications and inspection needs. We carefully plan production schedules to meet project deadlines, even for large or complex orders.

On the export front, Synergy Engineering Solution handles the full export process for global clients. Our reach includes the Gulf region (Oman, Qatar, Saudi Arabia, UAE, Kuwait), strategic European markets such as Spain and Germany, North America (USA and Canada), and multiple countries across Africa. We package flanges with corrosion-inhibitive wrapping and sturdy crates, label them with heat numbers and size information, and provide full export documentation (commercial invoices, inspection certificates, customs papers) to ensure smooth importation and delivery to your site — whether a refinery in Saudi Arabia, an offshore facility in UAE, a chemical plant in Germany, or an industrial installation in Africa.
If you’d like a detailed datasheet, dimensional drawings, or a price quote for specific sizes and pressure classes of UNS N08825 socket weld SWRF flanges, please send us your requirements (size, class, bore, surface finish, test needs, quantity, delivery location). We will promptly furnish a full technical proposal including MTCs, inspection plans, lead times, and delivered-cost pricing tailored to your project.

In order to alter the physical and mechanical characteristics of metal without altering its original shape and size, we offer a variety of heat treatment services, including hydrogen heat treatment, HIC testing, blasting and painting, cutting, arc welding, epoxy cutting, PMI testing, hydro testing, NACE testing, and SSC testing. Although heat treatment is frequently linked to a metal's increased strength, it can also be used to change specific manufacturability goals, such enhancing machinability, formability, ductility, etc. The metal and heavy manufacturing sectors use our services. Customers have expressed great pleasure with our services' precision, efficacy, cost, and prompt delivery.
