Oxygen pipeline flow rate value!
Thread Content
The current oxygen filling station project I am working on has a filling pressure of 16MPa. I need to calculate the pipe diameter and I don’t know what the flow rate should be! I hope someone can give me some advice, thank you in advance!
Oxygen station design specification "GB 50030-91": 1. When the oxygen working pressure is 10MPa or above, it should not be greater than 6m/s ； 2. When the oxygen working pressure is greater than 0.1MPa to 3MPa or below, it should not be greater than 15m/s ； 3. When the oxygen working pressure is 0.1MPa or below, it should be determined according to the allowable pressure drop of the piping system.
Recommended flow rate in the pipe: Suitable for liquid, gas and vapor oxygen at low and medium pressures to 50psi (gauge) and 50 to 100 degrees Fahrenheit (room temperature) 1800ft/min (low temperature) 4000ft/min
:) I have also seen what the classmate on the second floor said, but it is different from the common flow rate range table for fluids in the "Chemical Process Design Manual". This table says oxygen 0~0.5kgf/cm2 (gauge pressure) flow rate 5~10m/s 0.5~6kgf/cm2 (gauge pressure) flow rate 7~8m/s 6~10kgf/cm2 (gauge pressure) flow rate 4~6m/s 10~20kgf/cm2 (gauge pressure) flow rate 4~5m/s 20~30kgf/cm2 (gauge pressure) flow rate 3~4m/s
The "Chemical Process Design Manual" mentioned on the 6th floor refers to the economic flow rate, while the second floor talks about the standardized flow rate, and there are standards for implementation.
