Defining Maximum Gas Pipe Velocity | Flow Control …

Q: What is the typical Fire Fighting pipe velocity, and what is the maximum gas pipe velocity? A: For underground installations, 20 m/s is normal. Maximum velocity in a pipeline, on the other hand, is defined by available pressure, but in control and safety valves, it can be allowed up to 100 m/s.
