ZC Steel supplies high-performance Duplex and Super Duplex Steel Pipes, designed for applications requiring exceptional corrosion resistance, high strength, and durability. With a balanced microstructure of austenite and ferrite, duplex steels combine the toughness of austenitic stainless steels with the strength and stress corrosion resistance of ferritic grades.
Our duplex pipes are manufactured to ASTM, ASME, API, and ISO standards, with popular grades such as UNS S31803 (2205), UNS S32750 (2507), and UNS S32760. They are ideal for service in harsh chloride-rich, sour service, and offshore environments, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking.
Widely applied in the oil & gas industry, offshore platforms, subsea pipelines, desalination plants, chemical processing, and marine engineering, our Duplex and Super Duplex Steel Pipes ensure long service life and cost efficiency for critical projects.
