Characteristics of titanium tubing

November 07, 2023

1. Wall thickness of Titanium Tube

Heat conduction tube wall thickness by the use of conditions, tube plate materials, expanding the construction capacity of the tube operation, the tube end of the welding technology, etc. to decide, due to the small diameter of the heat conduction tube, the strength of the requirements are not high, so the actual use of the tube with a thinner wall thickness, in general, such as copper alloy tubes with a wall thickness of 0.9mm-1.2mm; replace titanium tubes in the corrosive small places, the available wall thickness of 0.3mm thin-walled welded tubes.

2. Thermal conductivity of titanium tube

Due to the thermal conductivity of different materials, thermal conductivity is different, such as titanium for 17W / (m - k), aluminum brass for lOOW / (m - k), 70 / 30 white copper for 29W / (m - k), therefore, can be controlled by the change in wall thickness of the thermal conductivity of the thermal conductivity of the tube. In the above materials, the thermal conductivity of titanium is small. Such as the use of thin-walled titanium welded tube, thermal conductivity, although worse than aluminum brass, but with 90/10 white copper is comparable to 70/30 white copper is better.

3. The economics of titanium tubes

Titanium tube unit mass price than copper alloy 2-6 times more expensive, but from the cost-effective considerations, titanium tube prices can compete with the copper alloy tube, due to the low density of titanium, wall thickness is the same, the same length of the titanium tube quality is only 50% of the copper alloy tube, when the titanium tube wall thickness of 50% of the copper alloy tube, the same heat transfer area of the titanium tube quality of the copper alloy tube only 1/4, according to the current Price level, the overall price of thin-walled titanium welded tube with the same aluminum copper tube, cheaper than the white copper tube. Visible, titanium tube in the price is competitive.
