SHIP BUILDING INDUSTRY
Ship building and off-shore drilling industry
Because of the nature of the business, materials used in shipbuilding and off-shore drilling must exhibit high brine corrosion resistance as they make the elements exposed to saline water.
Sea water is used onboard for various reasons, some of which may include cooling and heating, ballasting, waste disposal, firefighting and, through desalinization process, as a source of fresh water for sanitary purposes. All of them require piping systems, essentially consisting of pumps, valves, pipes and fittings, to be corrosion immune and provide reliability and fault-free operations in a long run. This is met by products made out of cupronickel. This alloy of copper and nickel is also used to manufacture condenser tubes while cupronickel sheets and plates are utilized as the hull skin. Elements and parts made out of 95/5 alloy are often used in broad spectrum of applications in shipyards and desalination plants.
Titanium is yet another material characterized by a very high resistance to corrosion (including sea water). Titanium and its alloys are frequently used in shipbuilding industry.
