UNS N10276 Hastelloy C276 Socket Weld Swrf Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N10276 Hastelloy C276 Socket Weld Swrf Flanges in Mumbai.
UNS N10276 (Hastelloy® C-276) is a nickel-molybdenum-chromium alloy engineered for outstanding resistance to a very wide range of aggressive chemical environments — including strong oxidizers, reducing media, chloride-bearing solutions and mixed acids. When supplied as Socket Weld SWRF (spigot-weld / raised-face) flanges, C-276 combines the alloy’s exceptional corrosion performance with the compact, leak-resistant benefits of the socket-weld joint. This makes Hastelloy C-276 flanges an ideal choice for critical piping systems in chemical processing, acid production, pollution-control, seawater handling and offshore applications where long life and low maintenance are priorities.
At Synergy Engineering Solution we manufacture, stock and export precision-machined UNS N10276 socket weld SWRF flanges from certified C-276 forgings and bar stock. Our process covers controlled material procurement, forging (where required), solution treatment, CNC machining and finishing under an ISO-compatible quality system. Every flange is fully traceable — delivered with mill test certificates (MTCs) and the option for PMI verification — and we offer project-specific NDT (UT / PT / RT) and third-party inspection to meet client or regulatory requirements.
Socket weld joints demand excellent fit-up and close tolerances for reliable welding and leak-free performance; we therefore machine socket bores, spigot depths and raised faces to tight concentricity and flatness specifications so welders can achieve consistent fillets and full penetration where required. The SWRF face simplifies gasket selection and improves sealing in bolted connections, while the socket geometry reduces stress concentration at the weld root — a real advantage in systems exposed to thermal cycling or vibration.
To support fast deliveries and project schedules, Synergy maintains inventories of commonly used sizes and pressure classes of Hastelloy C-276 socket weld flanges, and we can rapidly manufacture non-standard sizes, special bore profiles, or custom drilling patterns on request. Our packing and export practices are designed for long-distance shipments: anti-corrosion inner wrap, stout wooden crates, clear marking with heat numbers and part IDs, and complete export documentation so materials clear customs smoothly at destination.
Types Of Flanges manufacturer
Synergy Engineering Solution currently exports Hastelloy C-276 socket weld SWRF flanges across the Gulf (Oman, Qatar, Saudi Arabia, UAE, Kuwait), into Europe (Spain, Germany), to North America (USA, Canada), and to multiple countries throughout Africa and other global markets. We coordinate logistics, customs paperwork and project-specific compliance so clients in refineries, chemical plants, offshore platforms and desalination or mining operations receive materials ready for immediate installation.
we can follow up with a technical datasheet (chemical & mechanical tables, dimensional drawings, MTC examples) and a tailored quotation. Send the sizes, ANSI class (or PN rating), quantity and destination — and we’ll return availability, certified test documentation and a delivered-price proposal for your review.

Frequently Asked Questions (FAQ)
Q: Where are UNS N10276 flanges commonly used?
They are widely used in chemical processing, acid production, pollution-control, offshore platforms, and seawater piping systems where strong corrosion resistance is required.
Q: What certification is provided with Synergy Engineering Solution flanges?
Mill Test Certificates (EN 10204/3.1) are standard. PMI, UT, PT, RT and third-party inspection can be provided on request.
Q: Can you supply custom sizes and special machining?
Yes — we manufacture custom diameters, bore profiles, face finishes, and accept project-specific inspection requirements.
Q: Do you export globally?
Yes — we export to Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, Africa, and other worldwide regions with complete export documentation and secure packing.
Q: How are flanges packed for shipping?
Flanges are corrosion-wrapped, packed in wooden crates, labeled with heat numbers, and shipped with full documentation ready for customs clearance and installation.
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.
