UNS S32760 Super Duplex Steel Blind Blrf Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS S32760 Super Duplex Steel Blind Blrf Flanges in Mumbai.
UNS S32760 Super Duplex Steel Blind (BLRF) Flanges are engineered for the most demanding corrosive and high-stress applications. Made from a high-alloy mixture of chromium, molybdenum and nitrogen with controlled nickel content, S32760 delivers exceptional resistance to pitting, crevice corrosion and stress corrosion cracking while offering strength roughly double that of standard austenitic stainless steels. Blind flanges in this grade provide a reliable, full-face closure for piping and pressure-vessel systems where isolation, pressure testing, or future access is required — making them a preferred choice across oil & gas, petrochemical, desalination, offshore, and chemical processing plants.
Synergy Engineering Solution manufactures, stocks and supplies UNS S32760 Super Duplex BLRF flanges in a wide range of sizes, pressure ratings and face finishes to meet project needs. Their production emphasizes close metallurgical control, traceable heat treatment, and dimensional accuracy so each blind flange mates perfectly with mating rings, weld necks or lap joints. Stockholding enables rapid response for shutdown spares and urgent orders — an advantage for EPC contractors and maintenance teams working to tight schedules in remote or offshore locations.
As exporters, Synergy Engineering Solution serves an international customer base including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada and multiple African markets. Their export capabilities combine consolidated inventory, export documentation expertise and logistics partners experienced with hazardous / high-value cargo handling. This global reach means clients in the Middle East, Europe, North America and Africa can source certified Super Duplex blind flanges locally while still benefiting from factory pricing and consistent material quality.
Quality assurance and compliance are central to supply. Synergy typically furnishes mill test certificates, material traceability, dimensional inspection reports and can accommodate third-party inspection on request. Their flanges are produced to common international specifications and pressure-rating systems (ASTM/ASME/EN equivalents where applicable), and machining/welding prep is performed to industry standards so the flanges integrate easily into existing systems and pass client QA/QC protocols.
Types Of Flanges manufacturer
Applications for S32760 blind flanges are diverse: sealing off process lines during hydrostatic testing, providing safe closures for vessels and pumps, and isolating lines for maintenance or inspection. The combination of high yield/tensile strength and superior localized corrosion resistance also makes these flanges well suited for subsea tie-ins, chloride-bearing environments (brine, seawater), and sulfur-bearing process streams where standard stainless steels would be at risk.
Synergy Engineering Solution can tailor supply — offering custom machining, special surface finishes, bolting kits, or supply under project-specific documentation packages. For project quotations, lead-time confirmation, or technical datasheets (chemical composition, mechanical properties, heat treatment records), request a formal RFQ listing quantity, size/rating, and destination — Synergy’s export and technical teams typically respond with a detailed offer and delivery plan.

Frequently Asked Questions (FAQ)
Q: What makes S32760 better than standard 316/316L for blind flanges?
Super Duplex S32760 combines a high chromium-molybdenum-nitrogen chemistry with a duplex microstructure that gives much higher strength and superior resistance to pitting, crevice corrosion and stress corrosion cracking compared with 300-series austenitic stainless steels — especially in chloride-bearing environments like seawater or brines.
Q: Can Synergy supply blind flanges with third-party inspection and MTCs?
Yes. Standard supply includes Mill Test Certificates (EN 10204 / 3.1) and Synergy can arrange third-party inspection, PMI reports and package documentation tailored to export regulations for Oman, Qatar, KSA, UAE, Kuwait, Spain, Germany, USA, Canada and African destinations.
Q: Are custom face finishes, tapping, or bolt-hole drilling available?
Yes. Synergy offers custom machining: face finishes (machined / serrated / RTJ rings), tapped holes, bolting kits, companion rings and special packaging for export.
Q: What documentation should I provide in an RFQ?
Provide quantity, nominal size / rating (e.g. 10" CL300), flange standard (ASME B16.5, EN1092, etc.), special machining/finish requirements, and delivery destination. If project requires, include acceptance tests or certificate formats (e.g. 3.1 / 3.2 / NACE).
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.
