Issues with equipment pressure testing~~~~~~~
Thread Content
Pressure vessels must be pressure-tested before use; generally, a compressor is used to reach the test pressure. Can the time required to increase the pressure be calculated based on the size of the vessel and the performance of the compressor? For example, in a 10 m3 reactor, when operating at 25°C, a compressor with a capacity of 6 Nm3/h and a pressure of 2.5 MPa is used to increase the pressure. How long does it take to reach the test pressure of 1.0 MPa? What is the calculation process?

Is temperature not taken into account? The value on the compressor’s nameplate refers to standard conditions
This time isn’t the focus, right? According to the experimental requirements, one must not leave.
The key is pressure and pressure holding; it is necessary to install safety valves and pressure relief valves. . . . . .
The pressure increase shall not exceed 0.1 MPA per minute. The temperature increase shall not exceed 25°C per hour.
The estimated time is also important; work plans and scheduling rely on it
