Monel Flanges
DIN 2567 Monel flanges PN 25 and PN 40 are high-performance threaded flanges manufactured from copper-nickel-based alloys designed for excellent performance in highly corrosive environments, including seawater and acidic chemical systems. Built to DIN 2567 standards, these flanges offer outstanding resistance to corrosion, pitting, and stress cracking, making them ideal for use in marine engineering, chemical processing, and oil and gas industries.
Ladhani Metal Corporation is a trusted manufacturer and exporter of Monel flanges, delivering precision-engineered components known for durability, high mechanical strength, and long service life. The threaded design allows for easy, weld-free installation, making these flanges ideal for maintenance-critical systems and environments requiring non-permanent joints.
Pressure Ratings:
• PN 25 (25 bar / 362 psi): Suitable for corrosion-prone systems requiring reliable mechanical performance and resistance to seawater and acids.
• PN 40 (40 bar / 580 psi): Engineered for higher-pressure operations where both mechanical integrity and corrosion resistance are essential.
Flange Types:
• Threaded (Screwed) Flanges
Allows easy installation and removal, especially in systems requiring regular maintenance.
• Raised Face (RF) Flanges
Enhances sealing performance under elevated pressure and temperature conditions.
• Flat Face (FF) Flanges
Used in systems with flat mating surfaces, especially when brittle or non-metallic components are involved.
• Forged Threaded Flanges
Provide superior strength, resistance to impact, and tight dimensional tolerances.
• Custom-Machined Flanges
Available in various sizes, pressure classes, and Monel grades as per customer specifications.
