I need some engineering help...working with high pressure air?
and I need some specs for a tube that will hold up to 4500PSI air...I would like to "over engineer" it a bit so it could test at 6000PSI.
The tube will need to be 1 inch inside diameter. What material and wall thickness will I need? Is there a ready reference I could use on the net?

A schedule 160 pipe is good for about 6,000 psi per the ANSI piping code. The inside diameter will be 0.815 inches
A 1-1/2 pipe schedule extra strong ( 0.4 inch wall thickness) pipe will have a working pressure of about 7,000 psi and an internal diameter of 1.1 inches
For an exact 1 inch inside diameter and a pressuring rating of 4500 to 6000 psi will require a custom made pipe. There are no standard pipes that meet that requirement.
In all cases I am assuming carbon steel equivalent to ASTM A106 or A53

A) 35 because of the fact a hundred% is all or an entire B)0.35 C)80x9=720 so like a million/9 of 720 is 80 D)70x8=560 so approximately 0.12 of 560 is 70 E)840 and the whole volume of 8th graders is a million,050 F)50 s x 40 =2000 so 200cmx40= 8000 stable luck!!!

At that kind of pressure your best bet is to model it as a pressure vessel. Pressure vessel calculations take into account the fact that the "tube" is being stressed in all directions because of the air pressure.
There are a lot of references, the link below is one.
