Titanium tube has light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, coil heat exchanger, condenser, evaporator and transmission pipeline. Many nuclear power industries take titanium tubes as the standard tubes for their units.
Titanium Clarification:
Titanium is an isomer with a melting point of 1720 ℃ and a close packed hexagonal lattice structure below 882 ℃ α Titanium; It has a body centered cubic structure above 882 ℃, which is called β Titanium. Using the different characteristics of the above two structures of titanium, adding appropriate alloy elements to gradually change its phase transformation temperature and phase content to obtain titanium alloys with different structures. At room temperature, titanium alloys have three kinds of matrix structures, and titanium alloys are divided into the following three categories: α Alloy（ α+β) Alloy and β Alloy. China is represented by TA, TC and TB respectively.
α titanium alloy
It is α The single-phase alloy composed of solid solution, whether at general temperature or at higher practical application temperature, is α Phase, stable structure, higher wear resistance than pure titanium and strong oxidation resistance. At the temperature of 500 ℃ ~ 600 ℃, it still maintains its strength and creep resistance, but it cannot be strengthened by heat treatment, and the strength at room temperature is not high.
β titanium alloy
It is β The single-phase alloy composed of phase solid solution has high strength without heat treatment. After quenching and aging, the alloy is further strengthened, and the strength at room temperature can reach 1372 ~ 1666mpa; However, the thermal stability is poor and should not be used at high temperature.
