Duplex 2205 seamless pipe belongs to the duplex pipe group, which is the most commonly used group. These pipes are used more than other types of pipes due to their mild and balanced mechanical properties and lower cost. Duplex 2205 pipe can be used under high temperatures and pressures and is mildly corrosion resistant. The classification of dual-phase steel is mainly based on the addition of alloy materials such as chromium, molybdenum, and nickel.
Duplex 2205 seamless pipe is also highly resistant to chloride ion corrosion stress cracking. This property makes it a good choice for saltwater and marine applications. ASTM A790 Duplex 2205 welded pipe is strong enough for applications in the pulp and paper industry.
