The marine engineering environment features high salinity, high humidity and strong corrosiveness of seawater, which imposes extremely strict requirements on the corrosion resistance and strength of structural materials. The 2205 duplex stainless steel plate, with its outstanding resistance to chloride stress corrosion cracking, high strength and excellent welding performance, has become the ideal material choice in the marine engineering field.
Offshore oil platforms are a typical application scenario for 2205 duplex steel. In the seawater cooling system, fire protection pipelines, and structural support components of the platform, 2205 stainless steel plates are widely used to manufacture various pipes, storage tanks, and connection components. A certain South China oil and gas field project used 2205 duplex stainless steel plates to manufacture the seawater lift pump pipeline system. This material has operated continuously for many years in an extremely harsh environment with a chloride ion concentration of up to 30,000 ppm without any point corrosion or stress corrosion cracking phenomena, and its service life is much longer than that of ordinary austenitic stainless steel.
Seawater desalination projects are another important application field. In a large-scale seawater desalination project in the Middle East, 2205 duplex stainless steel plates were used to manufacture the high-pressure pipelines of the reverse osmosis device, the evaporator shell, and the seawater transportation pipelines. The high yield strength of the material enabled the reduction of the equipment wall thickness, thereby lowering the overall weight and manufacturing cost; at the same time, its excellent resistance to gap corrosion ensured the safety and reliability of the equipment during long-term operation.
In the field of marine engineering vessels, 2205 duplex stainless steel plates are widely used in the liquid cargo tanks and ballast tanks of chemical ships and liquefied gas ships. A 10,000-ton chemical ship uses 2205 duplex steel plates to make the inner walls of the liquid cargo tanks, effectively resisting the corrosion of various chemicals, while reducing the ship's own weight and improving the transportation efficiency.
The above application cases have fully demonstrated the outstanding performance and reliable performance of 2205 duplex stainless steel plates in the field of marine engineering.
