Synergy Engineering Solution offers UNS S32760 (also known as Super Duplex F55 / “Zeron 100”) spectacle blind flanges as a premium isolation / blanking solution for critical piping systems. S32760 is one of the more highly alloyed super duplex grades, combining excellent corrosion resistance, strength, and toughness. By producing and stocking spectacle blind flanges in S32760, Synergy meets the demand for the highest-performance flanges in corrosive, chloride-bearing, high-pressure environments. Their manufacturing capability ensures tight tolerances, full traceability, dimensional inspection, and flexibility in flange face types (RF, FF, RTJ) and bore/solid configurations to suit the client’s piping specification.
In terms of material performance, UNS S32760 delivers outstanding resistance to pitting, crevice corrosion, stress corrosion cracking, erosion and general corrosion in aggressive media — particularly seawater, chloride solutions, acid systems and chemical processing brines. Because it contains elevated alloying of chromium, molybdenum, tungsten, copper and nitrogen in its dual-phase (ferrite + austenite) microstructure, it often surpasses standard duplex (e.g. 2205) and even S32750 in harsh environments. The high strength also allows thinner sections or reduced weight, which is beneficial in large-diameter flanges and offshore piping.
As a stockist and exporter, Synergy maintains inventories of common sizes and pressure classes of S32760 spectacle blind flanges, enabling faster delivery to key markets. For more customized sizes, unusual drilling patterns or special machining, Synergy’s production arm undertakes manufacture to order. Their export footprint spans Oman, Qatar, Saudi Arabia, United Arab Emirates, Kuwait, Spain, Germany, the USA, Canada, and multiple countries across Africa — positioning them as a reliable supplier to global projects in oil & gas, desalination, petrochemical, marine and offshore sectors. Their logistics and export documentation infrastructure ensures smooth delivery and compliance with international standards.
From an application perspective, S32760 spectacle blind flanges are used to isolate lines for maintenance, pigging or pressure testing. The spectacle blank design (a solid disc linked to an open ring) permits visual verification of whether the line is “blinded” or open. In demanding environments — e.g. subsea systems, offshore facilities, desalination plants, chemical plants with chloride exposure — S32760 ensures longer life, reduced maintenance, and greater reliability compared to lower-alloy options. Synergy typically supplies these flanges with full material test certificates (MTCs), dimensional reports, optional NDE checks and PMI verification on request, giving confidence in critical installations.
UNS S32750 Super Duplex spectacle blind flanges from Synergy provide a robust, long-life isolation solution where strength and corrosion resistance are non-negotiable. They are suited to oil & gas, offshore, marine, petrochemical, desalination and chemical processing plants that demand reliable line isolation under aggressive service conditions. For project inquiries Synergy can provide material test certificates, dimensional drawings, and stock availability to help engineers and procurement teams select the right spectacle blind flange for their specific application.
Because S32760 is among the higher-end super duplex grades, customers often select it where lifetime cost, safety, and low risk are decisive factors. Synergy’s role as both a manufacturer and stockist means they can provide both standard and custom items, ensuring project timelines are met. Their global presence ensures that clients in the Middle East, Europe, North America, Africa and beyond can access S32760 spectacle blind flanges with consistent quality and support. In sum, these flanges from Synergy are tailored for the most demanding piping isolation needs where corrosion, strength and reliability cannot be compromised.

A: Super Duplex 2507 has higher chromium, molybdenum and nitrogen content than standard duplex (2205), which results in substantially improved pitting, crevice and stress corrosion cracking resistance and higher mechanical strength.
A: Yes — Synergy Engineering Solution supplies both solid (blind) and bored (open) spectacle blanks in S32750, with RF/FF/RTJ face options to match mating flanges.
A: Typical documentation includes MTC to EN 10204 3.1, chemical analysis (mill test certificate), dimensional inspection reports, and NDE or mechanical test reports on request. PMI verification is available for critical projects.
A: Yes — 2507 is weldable, but welding super duplex requires controlled procedures (pre/post-weld heat control, suitable filler metal, and cooling control) to preserve duplex balance and corrosion performance. Synergy can advise on welding procedures or provide finished parts.
A: Typical industries include offshore & subsea, oil & gas upstream and downstream, petrochemical, seawater desalination, marine, and chemical processing where chloride exposure and high strength are concerns.
A: Synergy maintains stock of common sizes and pressure classes and also manufactures to order for bespoke sizes or drilling patterns. For emergency or project shipments to Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada and African markets, contact Synergy’s export desk for real-time availability and shipping options.
