- Steam velocity through piping is the speed at which steam travels through a pipe. It's a crucial factor in designing steam systems because excessive velocity can cause several issues like erosion, water hammer, and increased energy consumption.

Recommended Velocities in Steam Systems. 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.
Online calculator to quickly determine Steam Velocity through Piping. Includes 53 different calculations. Equations displayed for easy reference.
Sizing pipes for superheated steam duty. Superheated steam can be considered as a dry gas and therefore carries no moisture. Consequently there is no chance of pipe erosion due to suspended water droplets, and steam velocities can be as high as 50 to 70 m/s if the pressure drop permits this.
In general, Steam pipes of sizes NPS 1/2 up to NPS 24 are widely used. Typically, for saturated steam, a velocity of 25 to 40 m/s is used, as above this, noise and erosion usually appear when the steam is wet. For longer supply lines, to avoid high-pressure drops, the velocity is limited to lower values.

Calculate ASME B31.1 power piping steam mass, velocity and flow rate from the steam table (IAPWS R7-97 Steam Table). Steam mass and volume can be calculated from steam temperature and pressure, and either steam mass, steam volume, or piping length.
The Steam Velocity Calculator is an online tool designed to calculate the velocity of steam flowing through a pipe. By inputting parameters such as steam pressure, pipe diameter, and steam temperature, the calculator provides an estimation of the steam velocity.
