Is there a problem with the drawing? What happens when there is both water pressure and air pressure? Air pressure, written as airtight again – I’m really drunk

I would like to ask how to understand drawings? If I suppress it, what order should I follow?
The airtightness requirements should be written in the line for the leak test: lol
It should be written in serial format; “Airtight/0.35” probably needs to be placed in the row related to leakage test requirements/pressure. Airtightness is a type of leakage test, and the airtightness pressure is equal to the design pressure.
The pneumatic test column should be diagonal; the airtightness test should be indicated in the leakage test column.
It’s written in sequence: first conduct a hydrostatic test, and once that is successful, carry out a leak test on the inner cylinder
As confirmed with the design team, this is critical data – how can it be stored in serial format?
The design was signed without going through the proper three-level review.
