UNS N06625 Inconel 625 Socket Weld Swrf Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N06625 Inconel 625 Socket Weld Swrf Flanges in Mumbai.
UNS N06625 (Inconel® 625) Socket Weld SWRF (Spigot Weld / Raised Face) flanges combine the exceptional mechanical strength and corrosion resistance of Inconel 625 with the compact, leak-resistant socket-weld connection most valued in high-pressure, high-temperature piping systems. Manufactured from the nickel-chromium-molybdenum-niobium alloy, these flanges resist pitting, crevice corrosion and stress-corrosion cracking in aggressive media (chlorides, sea water, sour gases) while retaining excellent creep and fatigue strength — making them ideal where reliability and long service life are essential.
At Synergy Engineering Solution we produce, stock and export precision-machined UNS N06625 socket weld SWRF flanges using controlled melting, forging and finishing processes to ensure consistent metallurgy and dimensional accuracy. Our process emphasises traceability from raw material (mill certificates) through machining and inspection; flanges are produced to conform with relevant international specifications and industry standards (ASTM/ASME nomenclature and dimensional standards are followed where applicable) and are checked with visual, dimensional and NDT methods appropriate to the order. This gives customers confidence that each flange will perform to expectation in critical systems.
Because socket weld connections demand tight tolerances for proper fit-up and weld integrity, our machining and facing operations are carried out on modern CNC equipment and finished to the surface and face tolerances customers require. The SWRF profile (raised face) simplifies gasket selection and improves sealing performance in bolted connections, while the socket-weld geometry reduces stress concentration at the joint — a combination that benefits piping in oil & gas, petrochemical, power generation, marine and chemical processing plants.
Synergy Engineering Solution acts not only as a manufacturer but also as a reliable stockist and global exporter. We maintain inventory of common sizes and pressure classes to shorten lead times, and we support customised orders (special sizes, face finishes, drilling patterns, and material heat-treat options) for project requirements. Our quality assurance and packing practices are suited for long-distance shipping; flanges are protected, properly documented and cleared for export so they arrive on site ready for installation.
Types Of Flanges manufacturer
Our export footprint covers the Gulf cooperation states — Oman, Qatar, Saudi Arabia, UAE and Kuwait — where offshore and onshore energy projects demand corrosion-resistant nickel alloys; major European markets such as Spain and Germany with advanced process industries; North America (USA and Canada) for high-end industrial and aerospace supply chains; and multiple regions across Africa. We coordinate logistics, customs documentation and any project-specific compliance needs so clients across these regions can source UNS N06625 socket weld SWRF flanges reliably and at competitive turnaround.
If you need detailed datasheets, dimensional drawings, mill test certificates, or a quote for specific sizes and pressure classes, Synergy Engineering Solution can prepare a fast technical proposal and stock check. Tell us your required size, class, face type and quantity and we’ll provide material certificates, lead time and packed shipment options to your location — whether that’s a refinery in Saudi Arabia, an offshore platform in Qatar, a chemical plant in Germany, or a project anywhere else in the world.

Frequently Asked Questions (FAQ)
Q: What makes Inconel 625 suitable for flanges in oil & gas and offshore projects?
Inconel 625 combines high nickel content with chromium, molybdenum and niobium which provides outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking in chloride-bearing and sour environments. Its excellent creep resistance and high strength at elevated temperatures make it a preferred choice for aggressive offshore and chemical service.
Q: Which certificates are supplied with Synergy Engineering Solution flanges?
Standard deliverables include mill test certificates (EN 10204/3.1 or equivalent). Additional NDT (UT, PT, RT), PMI chemical verification, and third-party inspection can be supplied per order.
Q: Do these flanges require special welding procedures?
Weld procedures for nickel alloys should follow qualified WPS/PQR and commonly use nickel-alloy filler wires. Socket weld joints require proper fit-up and qualified welding consumables compatible with Alloy 625 to preserve corrosion resistance and mechanical properties.
Q: Can you supply custom sizes and bore profiles?
Yes — Synergy Engineering Solution can produce custom dimensions, special face finishes, drilling patterns and provide heat treatment or testing as specified by the purchaser. Contact sales with size, class, quantity and required certifications.
Q: Typical lead time & packing for export?
Lead time depends on stock & quantity; common sizes are held in inventory to reduce lead time. Export packing includes corrosion-preventive wraps and wooden crates; full export documentation and customs assistance are provided.
