Advantages of titanium tubes for seawater desalination

Jul 07, 2023

Titanium pipe in seawater desalination equipment will gradually replace the original copper alloy pipe, and the titanium pipe has the following advantages:

1, The titanium pipe material is less. Under the same working conditions, the wall thickness of the titanium pipe is thinner, and the pipe dosage is less. Generally, the wall thickness of copper alloy pipe is 0.9mm-1.2mm; instead of titanium pipe, the thin wall pipe with wall thickness is 0.5mm.

2,Good thermal conductivity of the titanium pipe. The thermal conductivity of titanium is 17W / (mk), lOOW / (mk) for aluminum brass, and 29W / (mk) for 70 / 30 white copper, which is the minimum thermal conductivity of titanium. However, the use of thin-walled titanium pipe, although the thermal conductivity is worse than aluminum brass, but comparable to 90 / 10 brass, better than 70 / 30 brass.

3,Titanium tubes are more cost-effective. The price of titanium tube can compete with copper alloy pipe. Due to the low density of titanium, the wall thickness of the titanium pipe of the same length is only 50% of the copper alloy pipe. When the wall thickness of the titanium pipe is 50% of the copper alloy pipe, the quality of the same heat transfer area of the titanium pipe is only 1 / 4 of the copper alloy pipe.

4,Titanium tubes have a longer service life. Because the seawater is often mixed with sediment and Marine organisms, they attach in the heat transfer pipe and the pipe end, which will erode the copper alloy pipe, and the copper alloy will also be corroded by Br-in the seawater. And the titanium tube will not have this problem, especially in order to kill the bacteria in the seawater, have to inject oxygen, more need to use good corrosion resistance of the titanium pipe.
