DIN 2566 Monel flanges PN 16 are high-performance, corrosion-resistant threaded flanges designed for medium-pressure piping systems exposed to aggressive environments such as seawater, acids, and alkalis. These flanges are manufactured in accordance with DIN 2566 standards and are ideal for non-welded connections requiring strength, durability, and resistance to harsh chemicals. Ladhani Metal Corporation is a trusted manufacturer and exporter of Monel flanges, delivering precisely machined components with excellent dimensional accuracy and long service life. These flanges are widely used in marine, chemical, and offshore applications where standard stainless steels or carbon steels may fail due to corrosion. Flange Types: • Threaded (Screwed) Flanges: Enable fast installation and removal without welding, ideal for maintenance-friendly and modular systems. • Raised Face (RF) Flanges: Enhance gasket compression for improved sealing under pressure. • Flat Face (FF) Flanges: Used with flat-faced equipment or non-metallic components in moderate-pressure systems. • Forged Threaded Flanges: Offer enhanced strength and impact resistance due to forging. • Custom-Machined Flanges: Available upon request, tailored to specific dimensional and material needs. Available Monel Grades and Composition: 1. Monel 400 (UNS N04400) • Nickel (Ni): ≥ 63% • Copper (Cu): 28.0 – 34.0% • Iron (Fe): ≤ 2.5% • Manganese (Mn): ≤ 2.0% • Excellent resistance to seawater, steam, salt, and corrosive acids such as hydrofluoric and sulfuric acid. Applications: Used in marine hardware, chemical processing, offshore structures, pump shafts, and heat exchangers. 2. Monel K500 (UNS N05500) • Nickel (Ni): 63.0% min (includes cobalt) • Copper (Cu): 27.0 – 33.0% • Aluminum (Al): 2.30 – 3.15% • Titanium (Ti): 0.35 – 0.85% • Iron (Fe): ≤ 2.0% • Manganese (Mn): ≤ 1.5% • Silicon (Si): ≤ 0.5% • Carbon (C): ≤ 0.25% • Sulfur (S): ≤ 0.01% Applications: Ideal for high-strength, corrosion-resistant components such as pump shafts, marine equipment, fasteners, and valve components in oil & gas, marine, and chemical industries. Applications of DIN 2566 Monel Flanges: • Marine and Shipbuilding: Resistant to saltwater and brine environments • Offshore Oil & Gas Platforms: Corrosion-resistant in harsh subsea conditions • Chemical and Petrochemical Processing: Withstands acids and alkalis, including HF • Pump and Valve Systems: Durable and reliable in corrosive fluid transfer • Heat Exchangers and Condensers: Non-reactive in high-temperature, high-corrosion zones Key Features: • Manufactured to DIN 2566 standard with PN 16 pressure rating • Excellent resistance to corrosion, erosion, and acidic environments • Suitable for chloride-rich and saltwater systems • Non-magnetic and stable in extreme temperature variations • Threaded design allows easy assembly without welding • Supplied with material test certificates, inspection documents, and traceability Conclusion: DIN 2566 Monel flanges PN 16 from Ladhani Metal Corporation offer outstanding performance in highly corrosive and marine environments. Built from premium Monel alloys like Monel 400 and K500, these flanges provide superior strength, thermal stability, and longevity for critical systems.
