Regarding the flow rate of flammable and explosive gases in pipelines
Thread Content
For the flow of flammable and explosive gases in pipelines, is there any regulation on the flow rate to prevent static electricity? ? ? ? Dear heroes, please give me some advice.
Yes, it depends on different media, such as oxygen, hydrogen, and acetylene. . . There are special specifications that can be found.
The gas flow rate is generally relatively high. Normal operation is generally around 10 to 20m/s. Any higher than that, it is easy to generate static electricity.
What regulations? Are there specifications for inert gas flow rates in urea systems? ? ?
Maximum allowable flow rate of oxygen in the pipeline Oxygen working pressure MPa Maximum allowable flow rate m/s ≤0.1 Determined according to the pressure drop of the piping system >0.1～≤3.0 15 (carbon steel) 25 (stainless steel) >3.0～
What is the safe flow rate of oxygen?

During the static electricity safety training, there was a saying that compressed air has an approach speed of 30m/s. It is said that if the flow rate exceeds this, the risk of static electricity is very high, but the source or calculation basis of this data has not been found.
Check out the corresponding chapters of HG/T20570.6-95. If you have any other questions, you can add me as a Sichuan friend to communicate with each other.
