Development of TA18 titanium alloy thick-walled tubes for the petroleum industry

Development of TA18 titanium alloy thick-walled tubes for the petroleum industry

Currently, China mainly uses a combination of two-roll and three-roll cold rolling to produce TA18 titanium alloy tubes. The main problems encountered in the production of thick-walled TA18 titanium alloy tubes for the petroleum industry are: ① When using multi-roll rolling mills to roll thick-walled tubes with a diameter-to-thickness ratio <10, there are many rolling passes, and defects such as cracking and internal surface adhesion are prone to occur; ② The cold straightening method cannot guarantee that the straightness of the finished tubes meets the requirement of 0.3～1mm/m. In view of the above problems, the feasibility of two different cold rolling processes for producing TA18 titanium alloy thick-walled tubes is compared, the influence of annealing temperature on the microstructure and properties of the tubes is studied, and the subsequent processing technology of the tubes is also studied. The aim is to provide guidance for the industrial production of high-quality TA18 titanium alloy thick-walled tubes for the petroleum industry.
