I am currently new in this forum and just a senior high graduate, so pardon me if I have some errors in writing this questions. I have a cylindrical pressure chamber with approximately 80 cm in diameter and the length of 1.5 m and metal wall 1 cm in thickness. I know most pressure chamber have circular curved door on it, like this one for instance. I was wondering if I can put flat circular door on the chamber (because curved circular door are difficult and expensive to make). Can I put 8 bar of pressure to it? Could it withstand the pressure? And what is best suggestion on this pressure chamber? Thanks in advance.
