UNS N07718 Inconel 718 Socket Weld Swrf Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N07718 Inconel 718 Socket Weld Swrf Flanges in Mumbai.
UNS N07718, commonly known as Inconel® 718 (or Alloy 718), is a precipitation-hardening nickel-chromium alloy prized for its exceptional strength, good corrosion resistance, and stability at elevated temperatures. When fashioned into socket weld SWRF (spigot weld / raised face) flanges, Inconel 718 allows engineers to combine a compact, leak-resilient joint with superior materials performance — particularly in high-temperature, high-pressure, or cyclic loading environments. The socket weld design reduces local stress concentrations and is often preferred for smaller borelines or high-integrity systems.
At Synergy Engineering Solution, we manufacture, stock, and export Inconel 718 socket weld SWRF flanges with full process control. Starting from certified raw alloy 718 forgings or bar stock, we carry out forging, heat treatment, machining, and finishing under strict quality protocols. Each flange is traceable via mill test certificates (MTCs), and we support non-destructive testing (NDT) options such as UT, PT, or radiographic inspection as required by customers. The machining tolerances are tightly controlled to ensure the socket bore, spigot depth, and raised face geometry meet ASME/ANSI or customer-specific standards.
Maintaining an inventory of commonly used sizes and pressure classes (e.g. ANSI 150#, 300#, 600#, 900#, 1500#; or equivalent PN / metric classes), we are able to fulfill many orders with reduced lead times. For less common sizes or special dimensions, we accept customized orders. Because socket weld joints are sensitive to proper fit-up, we emphasize precision finishing of the bore and face, and ensure that surfaces are free of defects and ready for final welding on site.
As exporters, Synergy Engineering Solution handles all logistics, export documentation and packing to ensure your flanges arrive safely in your country. We currently serve major markets such as Oman, Qatar, Saudi Arabia, UAE, Kuwait in the Gulf; Spain and Germany in Europe; the USA and Canada in North America; and a variety of clients across Africa and other global regions. Our export packaging uses corrosion prevention wrap and sturdy wooden crates; all flanges are appropriately marked (grade, size, heat number, lot etc.) for easy identification.
