Leading Duplex 2205 Pipe Supplier in China
Duplex 2205 Pipe is a high-performance pipe made from a combination of austenitic & ferritic stainless steels. Consist of chromium, nickel, and molybdenum elements. It possesses excellent strength, corrosion resistance, & toughness. Ideal for use in harsh environments where other materials would fail.
The pipe’s dual-phase structure gives it superior resistance to stress corrosion cracking, crevice, and pitting corrosion. Furthermore, the Duplex 2205 Pipe has high ductility and low thermal expansion, thus it is suitable for use in cryogenic environments.
At Tuolian, we manufacture both welded and seamless forms of duplex 2205 pipe for various purposes. We can cut, groove, and thread duplex 2205 pipe to meet your requirements.
