Titanium pipe is a new type of metal material that has completely replaced traditional iron and steel pipes in some aspects.So,what makes it able to quickly replace traditional pipes?Let's take a look below.

The advantages of titanium tubes are:

1.Titanium tubes have high specific strength.The density of titanium alloy is generally around 4.5g/cm3,which is only 60%of that of steel.The strength of pure titanium is close to that of ordinary steel,and some high-strength titanium alloys exceed the strength of many alloy structural steels.Therefore,the specific strength(strength/density)of titanium alloy is much higher than other metal structural materials,which can produce components with high unit strength,good rigidity,and light weight.At present,titanium alloys are used for engine components,skeletons,skins,fasteners,and landing gear of aircraft.

2.Titanium tubes have high thermal strength.The use temperature is several hundred degrees higher than that of aluminum alloy,and it can still maintain the required strength at moderate temperatures.It can work for a long time at temperatures of 450-500℃.These two types of titanium alloys still have high specific strength in the range of 150℃to 500℃,while aluminum alloy shows a significant decrease in specific strength at 150℃.The working temperature of titanium alloy can reach 500℃,while that of aluminum alloy is below 200℃.

3.Titanium tubes have good corrosion resistance.Titanium alloys work in humid atmospheres and seawater media,and their corrosion resistance is much better than stainless steel;Has particularly strong resistance to pitting corrosion,acid corrosion,and stress corrosion;Has excellent corrosion resistance to alkali,chloride,organic substances such as chlorine,nitric acid,sulfuric acid,etc.However,titanium has poor corrosion resistance to reducing oxygen and chromium salt media.

4.Titanium tubes have good low-temperature performance.Titanium alloys can maintain their mechanical properties at low and ultra-low temperatures.Titanium alloys with good low-temperature performance and extremely low interstitial elements,such as TA7,can maintain a certain degree of plasticity at-253℃.Therefore,titanium alloy is also an important low-temperature structural material.

5.Titanium tubes have high chemical reactivity.Titanium has high chemical activity and reacts strongly with oxygen,nitrogen,hydrogen,CO,CO2,water vapor,ammonia,and other substances in the atmosphere.When the carbon content is greater than 0.2%,hard TiC will form in the titanium alloy;When the temperature is high,the interaction with N will also form a TiN hard surface layer;At temperatures above 600℃,titanium absorbs oxygen to form a hardened layer with high hardness;An increase in hydrogen content can also form a brittle layer.Titanium has a high chemical affinity and is prone to adhesion with friction surfaces.

6.Titanium tubes have low thermal conductivity and elastic modulus.Titanium has a low thermal conductivity and elastic modulus.The elastic modulus of titanium alloy is about half that of steel,so its rigidity is poor and it is prone to deformation.It is not suitable for making slender rods and thin-walled parts.During cutting,the rebound of the machined surface is large,about 2-3 times that of stainless steel,causing severe friction,adhesion,and bonding wear on the back surface of the tool.
