I would like to ask how to calculate the diameter of a hydrogen pressure relief pipe
Thread Content
Guys, I have a hydrogen buffer tank here. The diameter of the original hydrogen pressure relief pipe is too small, and it needs to be redesigned. But I don’t know how to do that. Is there anyone who can tell me how to calculate the diameter of a gas pressure relief pipe?
For pressures below 6 kilograms, what is the safe flow rate for hydrogen to be released?
8-12 meters per second; it is best if the pressure relief flow rate does not exceed 18–20 meters per second
According to Clause 12.0.1 of GB50177-2005 \"Code for Design of Hydrogen Stations\", for carbon steel hydrogen pipelines with a design pressure of 0.1~3.0 MPaG, the hydrogen flow velocity shall not exceed 15 m/s. The hydrogen emission pipelines shall comply with SH3009-2013 \"Design Code for Flammable Gas Emission Systems in Petrochemical Industries\"; the Mach number at the outlet of the pipes in the emission system network shall not exceed 0.7. The typical pressure relief flow rate is around 20 m/s
