In recent years, China has implemented a large number of ocean ships, offshore oil drilling platforms, seawater desalination, the construction of artificial reefs and other major projects, ocean engineering as an important bridge connecting human beings and deep-sea resources, is constantly ushering in technological and material innovation. Titanium metalis called “ocean metal”, is an important strategic metal material, with its high strength, resistance to seawater hydrothermal corrosion, sulfide corrosion, anti-microbial adhesion, high toughness, etc., in the ocean thermal energy conversion, seawater piping systems, and special firefighting equipment and other key areas to show extraordinary application value.
Therefore, making full use of marine materials - Titanium Materials and titanium alloys - will contribute to the development of the national marine strategy.
(A) Titanium Heat Exchanger in ocean thermal energy conversion ocean thermal energy conversion 
(B) seawater piping system of titanium application of seawater piping system as an important part of ocean engineering, its material selection is directly related to the system's operational efficiency and service life. Titanium with its high corrosion resistance to seawater (service life of 10 times that of steel), high strength and good fatigue properties, has become the preferred material for seawater piping system. The verification and assessment test of “titanium alloy” instead of “copper alloy” for manufacturing seawater piping system has been carried out in China, which not only verified the excellent performance of titanium material, but also demonstrated its reliability in the complex marine environment. The perfect performance of TA2 Titanium Seamless Pipe 
and its supporting pipe fittings and titanium flanges in the test has laid a solid foundation for the wide application of titanium materials in seawater piping systems.
(C) titanium alloy in the special fire fighting equipment in the innovative application of the Norwegian national oil supply company's innovative attempt to apply Titanium Tubing in the fire fighting equipment, but also created a new chapter in the application of titanium. Experiments have proved that in the case of seawater circulation, titanium can withstand more than 1,000 ℃ high temperature fire baking for up to two hours without being corroded, and its excellent resistance to wave impact and high temperature performance, for the ocean engineering in the fire safety provides a strong guarantee.
With the gradual deepening of China's ocean power strategy, in the field of offshore equipment, marine oil and gas field exploration and development, ships and other fields, titanium metal will certainly play a more important role in the future development of the ocean.
