3 "flow rate of gas pipelines 17.45m / s (flow rate by 300m³ / h, gas flow rate does not exceed the safe 50-60m / s), so 3" gas line can meet the design requirements.
3" gas phase pipeline flow rate of 17.45m/s (flow rate of 300m3/h, natural gas safe flow rate does not exceed 50-60m/s), so 3" gas phase pipeline can meet the design requirements.
3 "gas phase pipeline flow rate is 17.45m/s (flow rate is 300m3 / h, natural gas safety flow rate is not more than 50-60m / s), so 3" gas phase pipeline can meet the design requirements
