Duplex steel hydraulic fittings are widely used in applications requiring high strength and corrosion resistance. They are ideal for offshore oil and gas applications, where high-pressure water is handled and resist seawater corrosion. In the chemical industry these fillers ensure durability when exposed to acids and strong chemicals. It is used in desalination plants, power generation and the petrochemical industry, where reliability is critical in extreme conditions. In addition, steel duplex hydraulic fittings are used in marine products, pulp and paper manufacturing, and fire suppression systems to ensure efficient, watertight connections in industrial areas a strong.
