Are there any users who can calculate the thickness of orifice plates as well as their material? Help

Our plant’s dehydration and dehydrogenation towers are equipped with drain valves, which are of the ball valve type. Due to the high pressure inside the towers (50 bar), it is difficult to control the drainage process. The management ordered that flow-limiting orifice plates made from 3 mm thick aluminum be used; these orifice plates are installed in front of the drain ball valves (DN20 PN100 ball valves). I’m not sure whether opening these ball valves fully for drainage could lead to explosions, as the system downstream is low-pressure and connected using galvanized steel pipes. Since I don’t know exactly how strong 3 mm thick aluminum is, I would like to know if this approach is appropriate Is it reasonable? Is it possible to calculate the pressure difference or pressure that a 3 mm thick aluminum plate can withstand for a 20-inch pipe under a load of 50 kilograms?
Check some information and do some calculations to see what size hole would be appropriate; the error can be quite large.
Where can I find the information? What kind of materials are they specifically?
