The steam velocities or speeds below are commonly recommended as acceptable for steam distribution systems:
|Saturated Steam - high pressure||25 - 40||82 - 131|
|Saturated Steam - medium and low pressure||30-40||99 - 131|
|Saturated Steam at peak load||< 50||< 164|
|Steam and Water mix||< 25||< 82|
|Superheated Steam||35 - 100||100 - 300|
- Saturated steam - low pressure - is common for heating services and secondary process pipes.
- Saturated steam - high pressure - is common in powerhouse, boiler and main process lines.
- Superheated steam is common in power generation and turbine plants.
Sizing of steam and condensate pipe lines - pressure loss, recommended velocity, capacity and more.
Recommended max suction flow velocity when pumping boiling fluids.
Recommended max flow velocity on the delivery (pressure) side when pumping boiling liquids.
Calculate flash steam generation in condensate pipe lines.
Cavitation of impellers increases with water temperatures.
Typical fluid flow velocities for common liquids, gases and vapors.
Steam is a compressible gas where pipe line mass flow capacity depends on steam pressure.
Steam is a compressible gas where the capacity of a pipe line depends on the size of the pipe and the steam pressure.
