The design pressure of the storage tank is 0.5 MPaG. During purging, the factory air pressure is 0.6 MPaG; can the tank then serve as a source?

The tank is first pressurized to 0.4–0.6 MPaG (it’s likely difficult to reach 0.6 MPaG). Since a large amount of gas is required during purging, and the tank isn’t airtight, leaks may occur; therefore, it’s hard to achieve the pressure level required by the factory… The inlet and outlet valves are likely to be opened for purging before the tank reaches its designed pressure.
As the name implies, purging requires flow rate and pressure drop, not pressure; ensuring the flow rate is the key
