Could anyone tell me or direct me to a chart that shows the maximum operating pressure of 2" black seamless steel? Im getting it off of mcmaster.

Am I right in thinking that I should cut that in halve for any threaded components.

unless you will be operating the cannon at a couple thousand psi or above, you don't have to worry about it exploding.

I plan on going over a thousand (Hybrid).

I just want to know the pressure rating just to be safe.

No one answered his second question so I will. I think the threads can hold more than half the pressure but measure it as 1/2 the pressure just as a safety margin.

that's what most people go by. 1/2 the pressure the rest of the pipe is rated to
