2205 Duplex Pipes & Fittings
Riyaarth Overseas Industries is a leading manufacturer, exporter, and supplier of seamless and welded duplex steel pipes, duplex fittings, and duplex flanges. We offer a comprehensive range of duplex stainless steel pipe fittings, such as reducers, elbows, tees, crosses, stubs, and pipe bends. With one of the most extensive inventories of duplex steel pipes, we are among the few manufacturers in India capable of welding, bending, and forming duplex steel in various sizes and dimensions.
Why Choose Duplex Steel?
Duplex stainless steel, such as UNS S31803 and S32205, offers superior corrosion resistance and strength in demanding environments. With a PREN (Pitting Resistance Equivalent Number) of approximately 35, duplex steel outperforms 304 stainless steel (PREN: 19) and 316 stainless steel (PREN: 26), especially when it comes to stress corrosion cracking.
- Durability in Extreme Conditions: Duplex fittings and pipes are designed for high-performance corrosion resistance, making them ideal for industries such as boiler manufacturing, mixing tanks, and desalination plants.
- Comprehensive Product Range: We manufacture duplex flanges in a variety of sizes and pressure ratings, ensuring custom solutions for project-specific needs.
