UNS S32750 Super Duplex Steel Blind Raised Face (BLRF) Flanges are engineered to provide exceptional strength and corrosion resistance in highly demanding environments. Manufactured from Super Duplex Stainless Steel UNS S32750, these flanges exhibit a balanced microstructure of austenite and ferrite, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking. This makes them ideal for applications in chemical processing, marine engineering, and offshore oil & gas industries, where durability and reliability are paramount.
Synergy Engineering Solution & Exporter produces these flanges in compliance with international standards such as ASTM A182 F53, ASME B16.5, and EN 1092-1, ensuring high-quality manufacturing processes. The company offers a wide range of sizes and pressure ratings, from ½" to 48" and Class 150 to 2500, to meet diverse project requirements. Each flange is precision-machined to exacting tolerances, ensuring a perfect fit and optimal performance in critical piping systems.
The chemical composition of UNS S32750 includes approximately 25% chromium, 7% nickel, and 4% molybdenum, along with small additions of nitrogen and tungsten. This composition imparts excellent resistance to corrosion in chloride-rich environments and high mechanical strength, with a minimum yield strength of 550 MPa and tensile strength exceeding 800 MPa. These properties make the flanges suitable for high-pressure and high-temperature applications, including heat exchangers, pressure vessels, and desalination plants.
Synergy Engineering Solution & Exporter maintains a comprehensive inventory of UNS S32750 BLRF flanges, ensuring prompt delivery to clients across the Middle East, Europe, North America, and Africa. The company also offers customized solutions, including special sizes, pressure classes, and flange facings, to meet specific project requirements. With a commitment to quality and customer satisfaction, Synergy Engineering Solution & Exporter has established itself as a trusted supplier in the global market.
In addition to manufacturing, Synergy Engineering Solution & Exporter provides value-added services such as third-party inspection, material certification, and export documentation, facilitating smooth and efficient project execution. The company's experienced team offers technical support and guidance, assisting clients in selecting the appropriate flange specifications for their applications.
With a focus on quality, reliability, and customer service, Synergy Engineering Solution & Exporter continues to be a preferred choice for UNS S32750 Super Duplex Steel Blind Raised Face Flanges, delivering products that meet the highest industry standards and exceed client expectations.
