Adinox Overseas is a world-renowned supplier and exporter of high-performance Super Duplex S32760 Pipes, recognized for their superior mechanical integrity, resistance to corrosion, and durability in extremely aggressive conditions. Also known by the designation S32760 under the Unified Numbering System and included under ASTM A790 specification, the material belongs to the super duplex stainless steel group with a microstructure comprising a balance of austenite and ferrite. The pipes are especially designed to be resistant against pitting, crevice corrosion, and stress corrosion cracking, making them an extremely versatile material for application in oil and gas, petrochemical, power generation, and marine industries.
Our Super Duplex S32760 Pipes are produced with exact control over the chemical composition, involving a large proportion of chromium (24–26%), molybdenum (3–4%), and nitrogen. All these contribute to the excellent corrosion resistance feature of the material, particularly in chloride-containing and seawater applications. We supply the following pipes at Adinox Overseas in the form of seamless, welded, and ERW to accommodate different design requirements and pressure ratings. They are compliant with prominent international standards like ASTM A790 for seamless and welded super duplex stainless steel pipe and ASTM A928 for welded pipes by electric fusion welding with a filler metal.
The S32760 Super Duplex Pipes offered by Adinox Overseas find widespread application in subsea well oil systems, desalination plants, heat exchangers, offshore platforms, chemical process plants, and pressure vessels. The pipes are used very successfully in applications involving resistance to aggressive chemicals, exposure to large amount of chlorides, and acidic solutions. The pipes' weight reduction is facilitated by their high mechanical strength in applications involving high pressures, and their good weldability and formability make them easy to fabricate and install.
Our Super Duplex 2507 S32760 Pipes are available in a varied size, schedule, and wall thickness options to suit project requirements. All pipes are thoroughly inspected by us through rigorous non-destructive testing like hydro testing, eddy current inspection, and ultrasonic testing in order to confirm integrity and performance. Third-party inspection certificates, mill test certificates, as well as the traceability with complete documentation, are also offered by Adinox Overseas for all supplied material. One of the main benefits of UNS S32760 Pipes is their capability to endure temperatures from sub-freezing to above 300°C without compromising their structure.
