Ocean Engineering
Offshore oil mining equipment always contact with the medium Sulfides, ammonia, chlorine in seawater and crude oil.
Because of titanium has excellent corrosion resistance, so in the early of 1970s, the United States made pillar of offshore oil platform by titanium,, also manufacturing the titanium pipe heat exchanger and plate heat exchanger.
Titanium drilling weight is only half of the stainless steel pipe but with twice flexibility as stainless steel, and life is 10 times of stainless steel, there are several American companies used the titanium drill in offshore oil production in 2000 .
Titanium is not just used on major commercial/military ships, but it is found in various applications on fishing boats, deep sea submersibles and submarines. Titanium has been designed into marine applications when engineers are looking for low maintenance costs and reduced fuel consumption (due to weight reduction), to go along with the outstanding metallurgical properties associated with the metal.
01.
Offshore oil and gas
ALLTI METAL has been supplying pipe, tube, standard parts and other specialty products to oil platforms in the North Sea and beyond, get a lot of experience from the offshore titanium market.
New horizons for oil and gas development are rapidly expanding to include deeper, high-pressure,high-temperature wells. These severe conditions exceed design limitations of conventional CRA tubular materials such as duplex and super duplex stainless steels. Titanium material will be widely used in these fields day by day.
02.
Marine desalination
Since titanium has excellent corrosion resistance, so the production efficiency is much higher than the early using material of copper alloy, carbon steel and other materials, in desalination equipment, the main application of titanium is the heat transfer tube.
Marine applications of titanium include:
- ship propellers
- shipboard heat
- exchangers
- piping systems
- ballast systems
- waste systems
- tidal zone protection
- shipboard hardware
- tie-downs

The shipbuilding industry
Titanium and titanium alloy is widely used in the ship is, such as hull structure, deep-sea research vessel, ocean thermal energy conversion (titanium evaporator, titanium condenser and titanium sea Straw, titanium loop system, etc.), Marine Fisheries (titanium mesh for the artificial breeding, titanium tube heat exchanger to keep sea water temperature for fish needed)
A perfect environment for titanium to perform is in seawater. Titanium it at it’s best in seawater due to the corrosion resistance of the metal. Crevice corrosion, pitting, stress corrosion cracking, or microbiologically influenced corrosion in seawater are not issues when titanium is the material of choice.
