DIN 2628 Monel flanges PN 250 are high-performance weld neck flanges engineered in compliance with the DIN 2628 standard. Designed for high-pressure applications up to 250 bar (3625 psi), these flanges are constructed from Monel alloys, known for their exceptional resistance to corrosion, particularly in acidic and saline environments. Monel flanges deliver robust mechanical strength and thermal stability, making them suitable for challenging industrial applications that involve fluctuating temperatures, corrosive substances, and high mechanical stress. Ladhani Metal Corporation is a reliable global manufacturer and exporter of Monel flanges, providing products that meet exacting international standards for quality and performance. Our DIN 2628 PN 250 Monel weld neck flanges are extensively used in chemical processing, marine engineering, desalination systems, and offshore oil and gas installations. Known for superior build quality and long-term durability, these flanges ensure safe and efficient operations in pressure-sensitive systems exposed to harsh service conditions. Pressure Rating: • PN 250 (250 bar / 3625 psi): Suitable for systems requiring high-pressure endurance, secure sealing capabilities, and enhanced structural integrity. Flange Type: • Weld Neck Flanges Characterized by a long tapered hub that minimizes stress at the weld junction. Ideal for high-temperature and high-pressure applications. • Flat Face (FF) Flanges Provides an even surface for gasket compression, ensuring reliable sealing. Well-suited for connections involving cast components or brittle materials. Monel Grades and Composition: Monel 400 (UNS N04400) • Nickel (Ni): ≥ 63.0% • Copper (Cu): 28.0 – 34.0% • Iron (Fe): ≤ 2.5% • Manganese (Mn): ≤ 2.0% • Silicon (Si): ≤ 0.5% • Carbon (C): ≤ 0.3% Applications: Offers excellent resistance to seawater, hydrofluoric acid, and alkalis. Commonly used in marine piping, pump shafts, heat exchangers, and chemical processing equipment. Monel K500 (UNS N05500) • Nickel (Ni): ≥ 63.0% • Copper (Cu): 27.0 – 33.0% • Aluminum (Al): 2.3 – 3.15% • Titanium (Ti): 0.35 – 0.85% • Iron (Fe): ≤ 2.0% • Carbon (C): ≤ 0.25% Applications: Precipitation-hardened alloy providing greater strength and hardness than Monel 400. Suitable for valves, springs, and high-strength fasteners in corrosive environments including marine and chemical processing systems. Applications of DIN 2628 Monel Flanges PN 250: • Marine Engineering Highly resistant to saltwater corrosion, suitable for shipbuilding, subsea pipelines, and desalination plants. • Chemical and Petrochemical Processing Performs well in environments containing strong acids, alkalis, and chlorinated solvents. • Offshore Oil and Gas Used in systems that handle sour gas, brine, and other corrosive fluids. • Power and Energy Ideal for condenser systems and piping exposed to high-pressure steam and corrosive environments. • Pulp and Paper Industry Effective in processes involving sulfur compounds and acidic bleaching agents. Key Features: • Designed in accordance with DIN 2628 specifications • Rated for PN 250 (250 bar / 3625 psi) pressure systems • Weld neck configuration ensures superior mechanical strength and fatigue resistance • Flat face option supports uniform gasket pressure distribution • Available in Monel 400 and Monel K500 grades • Excellent corrosion resistance in marine, chemical, and high-saline environments • High mechanical strength and good thermal performance • Custom dimensions, pressure classes, and surface finishes available on request Conclusion: DIN 2628 Monel Flanges PN 250 from Ladhani Metal Corporation are engineered for high-pressure systems operating in some of the most demanding service environments.
