I’m working on my graduation project in my senior year; I noticed a problem at the end. Is it still possible to fix it? Experts, please help

The teacher specified a working pressure of 2.4 MPa for the shell side in the case of steam; the design pressure was set at 2.64 MPa. The data I found were all based on a standard of 2.5 MPa. Is that acceptable? I guess it’s not possible. Is there still any way to fix it? Experts, please help. .
It definitely won’t work. Recalculate and select based on a design pressure of 2.64 MPa; the process of making changes is relatively fast. Those that pass the calculations need no changes, while only those that fail the calculations or use substandard parts require modification.
It depends on the teacher in charge of your graduation project. To put it simply, it’s just to get a degree certificate. For our previous graduation project on gearboxes, we made a calculation error; we simply changed the result of one of the formulas, which led to several different answers. In the end, the teacher didn’t address the issue and gave us all grades anyway.
Talk to your supervisor to see if it’s possible to reduce the design pressure. For values above 2.5 MPa, the pressure resistance rating of many components has to be increased to 4.0 MPa; there’s a lot that needs to be changed in your case
It’s not that difficult either; it just involves changing the wall thickness and flange grade
