Duplex Steel 2205 (UNS S31803 / S32205) Ferrule Fittings

Manufacturer, Supplier & Exporter of Duplex Steel 2205 (UNS S31803 / S32205) Ferrule Fittings

Duplex Steel 2205 (UNS S31803 / S32205) Ferrule Fittings are advanced piping components designed for high-performance applications where superior corrosion resistance and strength are essential. These fittings are made from duplex stainless steel, which combines the properties of both austenitic and ferritic stainless steels. As a result, Duplex 2205 ferrule fittings exhibit excellent resistance to chloride stress corrosion cracking, high strength, and good weldability. They are commonly used in offshore platforms, chemical processing, desalination plants, and other critical environments.

Riddhi Siddhi Impex is a well-recognized manufacturer and supplier of Duplex Steel 2205 Ferrule Fittings in India. With a strong foothold in the stainless steel and alloy fittings industry, the company produces high-precision tube fittings, including single and double ferrule types, to meet diverse industrial demands. Their Duplex 2205 ferrule fittings conform to international specifications such as ASTM A182 and ASTM A479, ensuring reliability and performance in aggressive environments.

These ferrule fittings are especially suitable for applications involving high pressure and aggressive media, including brine, seawater, and acidic solutions. Duplex 2205’s high chromium, molybdenum, and nitrogen content gives it a corrosion resistance that outperforms standard austenitic grades like 304 and 316. The fittings are available in various configurations such as elbows, tees, unions, reducers, and connectors, and are machined to ensure leak-proof performance in instrumentation and process control systems.

Riddhi Siddhi Impex ensures timely and consistent supply of Duplex Steel 2205 Ferrule Fittings to key Indian cities including Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, and Rajkot.
