TA2 titanium tube can bear much pressure
Your 3MM thick 20 pressure completely no problem.
I will sell the wall thickness of 5 mm length is 60 and 40 two specifications to the time will go to the pressure to do the test report
Can not see which is more resistant to high pressure depends on what the media can be set to use TC4 or TA2 from the hardness of TC4 better than TA2 TA2 better than TC4 better
