DIN 2566 duplex flanges PN 16 are high-performance, corrosion-resistant flanges designed for medium-pressure threaded piping systems. Manufactured in compliance with DIN 2566 standards, these flanges provide a reliable, non-welded connection ideal for environments where both strength and corrosion resistance are critical. Ladhani Metal Corporation is a manufacturer and exporter of duplex stainless steel flanges, offering precise machining, dimensional accuracy, and material traceability. With excellent mechanical properties and enhanced resistance to stress corrosion cracking and pitting, DIN 2566 duplex flanges are suitable for demanding applications across the oil & gas, petrochemical, marine, and power generation industries. Flange Types: • Threaded (Screwed) Flanges: Enable easy assembly and disassembly without welding, ideal for maintenance-intensive or temporary systems. • Raised Face (RF) Flanges: Improve gasket sealing by focusing pressure on a smaller surface area, reducing the risk of leakage. • Flat Face (FF) Flanges: Used with equipment having flat sealing surfaces, especially in systems using cast or non-metallic components. • Forged Threaded Flanges: Offer superior strength and impact resistance with consistent dimensional tolerance. • Custom-Machined Flanges: Tailored to meet specific application needs including pressure class, material grade, and sizing. Available Duplex Grades and Composition: 1. Duplex 2205 (UNS S31803 / S32205) • Chromium (Cr): 21.0 – 23.0% • Nickel (Ni): 4.5 – 6.5% • Molybdenum (Mo): 2.5 – 3.5% • Nitrogen (N): 0.14 – 0.20% • Carbon (C): ≤ 0.030% • Manganese (Mn): ≤ 2.0% • Silicon (Si): ≤ 1.0% Applications: Used in environments with chloride exposure and aggressive chemical media, such as offshore platforms, desalination plants, pressure vessels, and structural piping systems. Applications of DIN 2566 Duplex Flanges: • Oil & Gas Pipelines: Resistant to sour service and high-pressure fluids • Chemical and Petrochemical Plants: Withstands corrosive chemicals and process fluids • Marine and Offshore Engineering: Ideal for seawater and salt-laden atmospheres • Power Plants: Used in high-temperature and high-pressure piping systems • Water Treatment and Desalination: Corrosion-free in brine and chlorinated water systems Key Features: • Manufactured to DIN 2566 standard with PN 16 pressure rating • Excellent corrosion and stress corrosion cracking resistance • High strength and toughness, even at low temperatures • Maintenance-friendly threaded design • Dimensional precision and smooth finish for leak-free operation • Supplied with test certificates, inspection reports, and full traceability Conclusion: DIN 2566 duplex flanges PN 16 from Ladhani Metal Corporation are engineered to deliver a perfect balance of strength and corrosion resistance in medium-pressure piping applications. Designed for long-term durability in harsh environments, these flanges offer dependable performance with minimal maintenance.
