Well really it's a steam turbine casing. I got a special order for this. How much would a consulting firm charge? I need to know wall thickness, and bolting, and if it needs a gasket. Built with 17-4PH stainless steel, the turbine should operate on 400-500C steam. I will hire an engineer from this forum if they would do it for less then a consulting firm.
It will look like this, the 3 pieces of the casing bolted together
