Duplex steels are popularly utilized in form of hydraulic fittings that need high strength and corrosion rates. They are perfect in offshore oil and gas operations, in which water of high pressure is worked in and they are resistant to corrosion by seawater. These fillers in the chemical industry provide long lasting stability with the acids and other strong chemicals. It is applied to the desalination plants, in the power production and the petrochemical sector, where reliability is clear in harsh conditions. Furthermore, the steel duplex hydraulic fittings are also applied on marine products, pulp and paper productions, and fire fighting products where watertight connection is required at industrial domains with high efficiency.
