Characteristics of titanium tubes

1. Wall thickness of titanium tube
The wall thickness of the heat conduction tube is determined by the use conditions, tubeplate material, construction capacity of tube expansion operation, and welding technology of tube end, etc. Because the diameter of the heat conduction tube is small and the strength requirement is not high, the pipe with thin wall thickness is used in actual use. Generally, the equal wall thickness of copper alloy tube is 0.9mm-1.2mm. Titanium pipes are used instead. In places where corrosion is small, thin wall welded pipes with wall thickness of 0.3mm can be used.

2. Thermal conductivity of titanium tubes
Due to the different materials of the thermal conductivity tube, the thermal conductivity is also different, such as titanium is 17W/(m·k), aluminum brass is lOOW/ (M · K), 70/30 white copper is 29W/(m· K), therefore, the thermal conductivity effect of the thermal conductivity tube can be controlled by the change of wall thickness. Of the above materials, titanium has the lowest thermal conductivity. If thin wall titanium welded pipe is used, although the thermal conductivity is worse than aluminum brass, it is comparable to 90/10 white copper, and better than 70/30 white copper.

3. Economy of titanium tube
Titanium pipe unit quality than copper alloy your 2-6 times, but from the consideration on the price, price of titanium tube can contend with copper alloy tube, due to the low density of titanium, wall thickness at the same time, the same length of titanium tube quality is only 50% of the copper alloy tube, when 50% of the wall thickness for copper alloy titanium tubes, the same heat transfer area of titanium tube quality is only 1/4 of copper alloy tube, According to the current price level, the overall price of the thin-walled titanium welded pipe is the same as the aluminum copper pipe, and cheaper than the white copper pipe. It can be seen that titanium tubes are competitive in price.
