In marine exploration, offshore oil production equipment such as platforms, crude oil titanium coolers, risers, pumps, valves, fittings, fixtures, etc. are in contact with seawater and crude oil in sulfide, ammonia, chlorine and other media. Equipment or parts are made of titanium which have been widely used in marine exploration.

   In addition, the comprehensive utilization of seawater is one of the important projects of marine engineering. Coastal power plant condenser is a large amount of equipment using seawater. After using titanium, the service life of condenser is extended, the heat transfer efficiency is improved, and the safety is improved. Titanium has been widely used in China to replace other materials in the manufacture of seaside power plant condensers. Up to now, more than 30 power plant units have adopted all-titanium condensers and tube condensers.

   Looking forward to the future, ocean engineering, as a new titanium market, has developed rapidly in recent years. In the case of energy shortage, many countries in the world are exploiting and utilizing the ocean from offshore to deep sea. The excellent properties of titanium can well meet the requirements of people's application in marine engineering, so the application fields are very wide. It is expected that titanium used in marine engineering will become a larger application market . Marine engineering materials, in addition to the requirements of anti-corrosion environment, but also require high performance, high function, safety and reliability, practicability and low cost.

    The following are described in terms of ships, seawater desalination, marine facilities and marine exploration. In the field of warship application, harsh working conditions require excellent materials. Ships and some of their equipment parts such as hulls, heat exchangers, pumps, valves, pipelines and other long-term immersion in the sea water, are very vulnerable to sea water corrosion. Titanium can solve the problems of submarine pipeline leakage caused by corrosion/erosion and ship failure, caused by marine organisms. It not only has excellent seawater corrosion resistance, but also can reduce the weight of the ship, reduce maintenance costs and prolong service life. From ferries, fishing boats, naval vessels to deep-sea submarines, titanium has been widely used. Its main application fields include plate/frame and shell, tubular heat exchanger, water supply system, steam condenser, surface condenser pipeline system, cooling water system, oil pollution treatment system, deck drainage system, cabin bottom, navigation system, railings, ship propulsion system, deep-sea submarine pressure vessel, naval vessel main condensation Components, pressure parts of ships, etc.
