Application of titanium rod, titanium wire and titanium plate in the shipbuilding industry

Nuclear submarines, deep submarines, atomic icebreakers, hydrofoil vessels, hovercraft, and minesweepers use titanium rods, titanium plates, propellers made of titanium wire, submarine whip antennas, seawater pipelines, condensers and heat Switches, acoustic devices, fire fighting equipment, etc. The main applications of titanium alloys are industrial pure titanium, Ti-6Al-4V, Ti-6Al-4VELI, Ti-6Al-2Nb-1Ta-0.8Mo, Ti-3Al-2.5V, and ЛT-3B alloy [Ti- (3.5 ~ 5.0) Al- (1.2 ~ 2.5) V], T-7M [Ti- (1.8 ~ 2.5) Al- (2.0 ~ 3.0) Zr].
In addition, titanium nickel alloys with shape memory characteristics have been used as pipe joints in submarines. This is very practical when using memory alloys as joints in seawater when it is difficult to weld by ordinary methods.
Deep-sea vessels used for mining manganese nodules in the ocean in the United States are prepared to use titanium rods. A deep-sea vessel uses hundreds of Ti-6Al-4V titanium alloy rods to produce large-caliber thick-walled pipes with a thickness of 10mm and a diameter of 250mm. Deep-sea marine pumps for mining manganese nodules are used to salvage seawater with manganese blocks under vacuum pressure. This pump requires resistance to seawater pressure of 5000-6000m deep, and also requires resistance to corrosion and friction. Titanium is suitable for manufacturing such pumps. material.
