Titanium pipe is a new type of metal material that has completely replaced traditional iron pipes and steel pipes in some respects, so what makes it possible to replace traditional pipes so quickly?
The advantages of titanium tubes
1. The density of titanium alloy is about 4.5g\\u002Fcm3, only 60% of steel. The strength of pure titanium is close to that of ordinary steel, and some high-strength titanium alloys exceed many alloy structural steels. Therefore, the specific strength (strength\\u002f density) of titanium alloy is much higher than other metal structural materials, and parts with high unit strength, good rigidity, and lightweight can be manufactured. At present, titanium alloys are used in aircraft engine parts, skeletons, skins, fasteners, landing gears, etc.
2. Titanium tube has high thermal strength. The operating environment temperature is several hundred degrees higher than that of aluminum alloy, and it can still maintain the required strength at medium and different temperatures. It can develop and work for a long time at a temperature of 450-500°C. The research still has a very high specific strength, while the specific strength of aluminum alloy can decrease obviously at 150 °C. The working temperature range of titanium alloy can reach 500°C, while that of aluminum alloy material is below 200°C.
3. Titanium tube has good corrosion resistance. Titanium alloy works in a humid atmospheres and seawater medium, and its corrosion resistance is much better than that of stainless steel, especially it has strong resistance to pitting corrosion, acid corrosion, and stress corrosion, and has excellent corrosion resistance to alkali metals and other substances. However, titanium has poor corrosion resistance to media containing reducing oxygen and chromium salts.
4. Titanium tube has good low-temperature performance. The mechanical properties of titanium alloys can be maintained at low and high temperatures. Titanium alloys have good low-temperature performance and extremely low interstitial elements, such as TA7, which can maintain a certain degree of plasticity at -253 °C.
5. Titanium tube has high chemical activity. Titanium has high chemical activity and reacts strongly with O, N, H, CO, CO2, water vapor, and ammonia in the atmosphere. When the carbon content is greater than 0.2%, hard TiC will be made of titanium alloy. When the temperature is high, the hard surface layer of TiN is also formed through the interaction with N; when the temperature is higher than 600 ° C. As the content increases, an embrittlement layer is also formed. The titanium also has a high chemical affinity and easily adheres to frictional surfaces.
6. The coefficient of thermal conductivity of the titanium tube is small, and the modulus of elastic material is small. The thermal conductivity of titanium is small, and the elastic dynamic modulus is small. The effective modulus of elasticity of titanium alloy is about 1/2 of that of steel, so its rigidity is poor and easy to deform. The amount of spring back on the surface of the enterprise is very large, about 2 to 3 times that of Chinese stainless steel, resulting in severe movement friction, adhesion, and bonding wear of different tool flanks.
