Duplex Steel pipe is widely used in applications requiring positive strength and corrosion resistance. It is used in the oil and gas industry, especially in offshore corrosive areas, to transport oil and gas chemicals. It is also used in the petroleum and chemical industries for handling strong water. In the marine industry Duplex steel pipe serves in marine water systems and desalination plants. In addition it is used in heat exchangers, power plants and the pulp and paper industry, where durability and resistance to stress corrosion cracking are required.
