Titanium alloy parts for ships
Titanium and titanium alloy vessels available on the ship a lot of parts, it is difficult to inventory clear, and now can only talk about those who have a practical and effective display of components.
Comprehensive performance of the sonar shroud
Titanium alloy sonar shroud has excellent overall performance. Titanium alloy shroud made an in-depth comprehensive study, and achieved fruitful results, and now gradually switch to titanium alloy.
Titanium propeller life longer than copper alloy 5 times
Ship propeller requirements of the material are: high strength, strong anti-fatigue properties of seawater, erosion resistance and cavitation erosion. For existing materials, titanium alloys are the material of choice for these requirements. However, long-term use and operation shows that the advantages of titanium alloy propeller and its shaft in manufacturing cost have not yet been completely realized. Therefore, the application of titanium alloy propellants has not yet reached the stage of universal pragmatic application and remains to be further developed and popularized. In the titanium propeller components also include rudder and bearing.
Engine exhaust cooling pipe and muffler
In mid-sized speedboats, the engine exhausts gas at temperatures as high as 500 C. Exhaust gas is discharged from the stern through the pipelines inside the vessel. On the one hand, cooling seawater is needed to cool the exhaust gas to cool the exhaust gas. On the other hand, mufflers are installed to reduce exhaust noise Below 60dB. Titanium is a good material for mufflers: Durable and long-lasting at higher temperatures than aluminum, lower density than stainless steel, and good sound-dampening.
The reasons for using titanium to make the mixer are as follows: the temperature of the high-temperature end is as high as 500 ° C, which requires the material to have a good high-temperature endurance strength; the temperature at the low-temperature end is not high and about 100 ° C but requires high corrosion resistance . At present, the frequency conversion devices of medium-sized high-speed ships are mostly made of aluminum, but the high-temperature performance of aluminum is not good, and cracking easily takes place in the weld areas and the heat-affected zone, and the low-temperature end is easily corroded by seawater; if the stainless steel is used, Corrosion cracking. Their useful life is 5a ~ 10a, during which multiple repairs are required.
Piping, valves, plumbing piping, such as engine cooling water and fire seawater, are very poor working conditions and have been made of copper in the past, as well as internally coated steel and stainless steel pipes, but their service life Not long, only 2a ~ 5a, if the switch to the titanium pump, titanium valve, titanium pipe life of up to 25a ~ 30a, not only the total cost dropped significantly, but also safe and reliable during operation, will not occur corrosion, leakage and Other safety incidents. The company is located in:
At present, only titanium and titanium alloys in all the structural materials are in a position to fulfilling this requirement, which is also the most cost-effective material in terms of aspect.
