What is the maximum flow rate for a DN80 medium-pressure steam pipe at 1.5 MPa?
It needs to be calculated; one can look up the flow rate and density at that pressure
It is related to temperature to some extent, but the impact isn’t very significant. For saturated steam, the theoretical limit is 3.7 tons/h; of course, it’s possible to go a bit higher with little impact (up to 5 tons is no problem), while superheated steam allows for much higher values
With a steam flow rate of 30 m/s and a density of steam at 1.5 MPa of approximately 7.597 kg/m3, the flow rate comes out to 4.122 t/h； Of course, if the steam flow rate is higher, the flow volume can also be increased, but excessive pipe losses make it uneconomical
