Blind Flanges (BL): Used to seal the end of a pipeline. Socket Weld Flanges (SW): Used for small bore applications. Lap Joint Flanges (LJ): Used with a stub end, providing easier alignment and disassembly Grades of Titanium Used for Flanges: Grade 2 (CP-Titanium - Commercially Pure Titanium): Composition: 99.2% pure titanium. Properties: Excellent corrosion resistance, moderate strength, highly ductile, good weldability. Grade 5 (Ti-6Al-4V - Titanium Alloy): Composition: 90% Titanium, 6% Aluminum, 4% Vanadium. Properties: High strength, excellent corrosion resistance, good fatigue strength, and slightly more difficult to weld. Conclusion: Grade 2 is ideal for applications requiring excellent corrosion resistance and ease of fabrication, while Grade 5 provides superior strength and is used in demanding applications like aerospace and high-performance industrial systems. Both grades offer excellent properties for titanium flanges used in a wide variety of industries. we also deal in various material in DIN2543 such at Stainless steel, duplex, super duplex, Inconel, Monel and carbon steel
