im little newbie, i have builded few combustions and one pneumatic, now im thinking to make a better and more powerful piston valve pneumatic.

so, to the business. i have 77mm OD/ 70mm ID steel pipe, how much pressure do you think it will hold? the ends will be plugged with machined steel or aluminium plugs.

Steel pipe comes in several schedules and grades. Example, Sched 40 or 80. Some is seamless, some is drawn on Mandrel, etc. You will need to identify the pipe in question to find it's rating.
