UNS S32750 Super Duplex Steel Socket Weld Swrf Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS S32750 Super Duplex Steel Socket Weld Swrf Flanges in Mumbai.
UNS S32750 Super Duplex Steel Socket Weld (SWRF) Flanges are engineered for the most demanding piping systems where exceptional strength and localized-corrosion resistance are required. The super-duplex chemistry and balanced ferrite-austenite microstructure give S32750 a high pitting resistance and superior resistance to chloride stress-corrosion cracking compared with standard austenitic stainless steels — making these socket-weld flanges ideal for seawater, brine, chemical process streams and high-chloride petrochemical services. The socket-weld design (SWRF) provides a compact joint suitable for smaller bore piping where a full penetration weld is not required or where space is limited.
Synergy Engineering Solution manufactures, stocks and exports UNS S32750 SWRF flanges in a wide range of nominal sizes, pressure classes and face finishes to match project needs. As a manufacturer and stockist they control metallurgy, solution-annealing and machining to ensure dimensional accuracy and metallurgical traceability. Stocked items allow fast response for maintenance spares and shutdowns, while factory production covers project batches and bespoke dimensions for EPC and contractor requirements.
As an exporter, Synergy Engineering Solution serves clients across the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada) and many African markets. Their export capability includes export-grade packing, consolidated shipment handling, customs documentation and full technical paperwork (Mill Test Certificates, traceability and inspection reports). This global distribution network ensures customers receive certified S32750 SWRF flanges that comply with regional procurement and quality requirements.
Application-wise, S32750 socket weld flanges are chosen for subsea tie-ins, seawater cooling systems, desalination plant piping, offshore topsides, chemical process lines and high-pressure systems where corrosion and mechanical loads coincide. The combination of high yield strength and good toughness lets engineers specify thinner sections or lighter assemblies compared to conventional stainless steels — saving weight without sacrificing safety or service life.
Types Of Flanges manufacturer
Quality assurance and certification are central to Synergy’s supply. Typical delivery packages include Mill Test Certificates (with heat/lot traceability), dimensional inspection reports, positive material identification (PMI) results on request, and third-party inspection options. Synergy can also support project-specific qualification such as NACE/ISO 15156 requirements, special surface finishes, and packing protocols required by international buyers.
For project enquiries Synergy Engineering Solution offers technical assistance to select the correct flange type, size, pressure rating and welding procedure. They can supply ready-to-install SWRF flanges with companion hardware, custom machining (counterbores, tapped holes), and tailored documentation for export to Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada and across Africa.
