Durability: Excellent resistance to pitting and crevice corrosion, ensuring long-term durability in harsh conditions. Weldability: While duplex flanges are weldable, the welding process must be carefully controlled to prevent issues like sensitization or intermetallic phases. Types of Duplex Flanges (DIN 2543): Weld Neck Flanges (WN): These flanges have a tapered neck for welding directly to pipes, providing extra strength and durability in high-pressure applications. Slip-On Flanges (SO): These are easy to install and are placed over the pipe, then welded inside and outside. Blind Flanges (BL): Used to close the end of a pipe or system, preventing fluid flow. Socket Weld Flanges (SW): These flanges have a socket into which the pipe is inserted and then welded, commonly used for small-bore systems. Lap Joint Flanges (LJ): These are paired with a lap joint stub end and allow for easy alignment and disassembly. Common Duplex Stainless Steel Grades for Flanges: Grade 2205: Composition: Contains approximately 22% chromium, 5% nickel, and 3% molybdenum.
