# Recommended Velocities in Steam Systems

## The steam velocity in a steam distribution system should be within certain limits to avoid excessive wear and tear

The steam velocities or speeds below are commonly recommended as acceptable for steam distribution systems:

Recommended Velocities in Steam Systems
Steam SystemVelocity
(m/s)(ft/s)
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.
