Monel Flange
DIN 2632 Monel flanges PN 10 are high-performance weld neck flanges manufactured to meet the DIN 2632 standard, specifically designed for medium-pressure applications up to 10 bar (145 psi). These flanges are made from Monel, a nickel-copper alloy known for its outstanding corrosion resistance, particularly in marine and chemical environments. With excellent mechanical strength and superior durability in highly aggressive conditions, DIN 2632 Monel flanges provide a reliable solution where standard materials may fail.
Ladhani Metal Corporation is a leading global manufacturer and supplier of Monel flanges, delivering consistent quality, dimensional accuracy, and full compliance with international standards. Each flange is meticulously tested to ensure optimum performance under demanding industrial conditions.
Pressure Rating:
• PN 10 (10 bar / 145 psi): Suitable for medium-pressure piping systems requiring high corrosion resistance and mechanical stability.
Flange Type:
• Weld Neck Flanges
Designed with a long tapered hub that ensures precise pipe alignment and reduces localized stress at the flange connection. Ideal for high-integrity, high-strength joints.
• Flat Face (FF) Flanges
Flat face configuration ensures uniform gasket compression, making them ideal for systems using soft gaskets or connecting to cast components.
Monel Grades and Composition:
Monel 400
• Nickel (Ni): Minimum 63%
• Copper (Cu): 28–34%
• Iron (Fe): 2.0–2.5%
• Manganese (Mn): ≤ 2.0%
• Silicon (Si): ≤ 0.5%
• Carbon (C): ≤ 0.3%
Applications: Monel 400 is widely used in chemical and marine environments due to its excellent resistance to seawater, acids, and alkalis. It is commonly used in heat exchangers, seawater piping, pumps, and valves handling corrosive media.
Monel K500
• Nickel (Ni): 63% minimum
• Copper (Cu): 27–33%
• Aluminum (Al): 2.3–3.15%
• Titanium (Ti): 0.35–0.85%
• Iron (Fe): ≤ 2.0%
• Carbon (C): ≤ 0.25%
Applications: Monel K500 combines the corrosion resistance of Monel 400 with greater strength and hardness due to age-hardening. It is used in marine shafts, chemical processing equipment, oil and gas tools, and high-strength fasteners.
