DIN 2628 Inconel flanges PN 250 are high-strength weld neck flanges manufactured in accordance with the DIN 2628 standard. Designed to operate in high-pressure systems up to 250 bar (3625 psi), these flanges offer outstanding performance in extreme environments involving high temperatures, corrosive chemicals, and mechanical stress. Made from Inconel superalloys, they provide excellent resistance to oxidation, thermal fatigue, and pitting, making them ideal for critical applications in demanding industries. Ladhani Metal Corporation is a globally trusted manufacturer and exporter of premium Inconel flanges. Our DIN 2628 PN 250 Inconel weld neck flanges are widely used in sectors such as chemical processing, offshore drilling, aerospace, power generation, and marine engineering. Known for precision engineering, reliability, and resistance to harsh service conditions, these flanges are a preferred choice in pressure-intensive and corrosion-prone systems. Pressure Rating: • PN 250 (250 bar / 3625 psi): Suitable for high-pressure pipelines requiring superior sealing, thermal resistance, and structural integrity. Flange Type: • Weld Neck Flanges Designed with a tapered hub to reduce stress concentration at the weld point. Ideal for high-pressure and high-temperature environments. • Flat Face (FF) Flanges Flat face design ensures even gasket compression, preventing flange warping and providing secure sealing, especially when used with cast or brittle materials.
