Developed as per ASME and ANSI norms, duplex steel flanges are available in weld neck, lapped, socket welded, and slip-on type design choices. To meet exact application requirements, flanges are available in the ring-type joint, raised, or flat face-based design options. Flanges are used as integral parts of different sorts of pipelines for transferring fertilizer, oil, gas, and chemical. Duplex steel flanges contain elements like molybdenum, chromium, and nitrogen that make flanges strong enough to resist crevice corrosion and chloride pitting. Long-lasting quality is one of the key features of these steel flanges.
