The operating pressure is 4 MPa; is it necessary to conduct low-pressure airtightness testing and medium-pressure airtightness testing?

The system operates at a pressure of 4 MPa. Is it necessary to conduct low-pressure and medium-pressure leak tests? Can we proceed directly with the high-pressure leak test?
There are 4 pressures already – do you really think it’s not necessary to do it? ?
Whether to achieve airtightness has nothing to do with pressure; it is determined by the properties of the medium
Isn’t it ascending from low to high? Pressurization requires a gradient!
It is done under several levels of pressure, from low to high. Gradient~
These are two separate things: 1. Strength test, 2. Airtightness test (determined by the type of medium)
Why can’t it be made airtight under high pressure directly?
Are you referring to the water pressure test and the airtightness test?
In reality, we also increase the pressure from low to high, achieving airtightness step by step.
Are you referring to the leakage test? Do media that are extremely and highly hazardous require leakage tests?
