Selection of steam pipeline flow velocity
Thread Content
For steam at an absolute pressure of 0.4 MPa, what flow rate is appropriate for a DN50 pipeline? I’m new to pipeline systems; please give me some advice~~~
The recommended flow velocity for low-pressure steam in chemical process design manuals is generally 15–20 meters per second.
For the selection of steam flow rate, generally, a slower flow rate is chosen for steam with smaller pipe diameters, while a faster flow rate is appropriate for steam with larger pipe diameters. Generally, a flow rate of 18–20 m/s is sufficient for diameters ranging from 50 to 200. If the pipe diameter is around 500, then a flow rate of 28–30 m/s is required. Actually, this is a bit general; it is mainly determined by the pipeline resistance.
I’ll stop by to show my support; thanks for speaking up.
