Nov 4, 2012 · The steam velocities or speeds below are commonly recommended as acceptable for steam distribution 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.
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.
Online calculator to quickly determine Steam Velocity through Piping. Includes 53 different calculations. Equations displayed for easy reference.
Use our calculator to design your new steam pipes correctly on pressure drop and velocity methods. Connect to learn more about steam and sustainability.
Velocity: Steam velocity within the pipes should be maintained within acceptable limits. Very high velocities can lead to erosion, while low velocities may cause condensation and reduced efficiency.
Nov 4, 2012 · Steam is a compressible gas where the capacity of a pipe line depends on the size of the pipe and the steam pressure. This table below can be used for fast calculation of steam pipes sch. 80. in general - 80 ft/sec is a recommended steam velocity
Condensate piping velocities (two-phase flow/flash steam): 4,500 feet per minute. condensate piping velocities (liquid only): 420 feet per minute. siziNG steAM liNes For Velocity. Fomula for velocity in steam piping: 2.4 x flow x specific volume. Velocity= cross-sectional area. Flow = lbs. per hour.
Nov 21, 2018 · The ideal steam velocity depends on various factors such as pipe size, pressure, temperature, and the type of steam application. Generally, steam velocities are kept within a certain range to ensure efficient and safe operation.
Aug 10, 2017 · Process steam velocities: 10,000 feet per minute. Condensate piping velocities (two-phase flow/flash steam):4,500 feet per minute. Condensate piping velocities (liquid only):420 feet per minute. Sizing Steam Lines for Velocity. Formula for velocity in steam piping: Velocity = 2.4 x flow x specific volume cross-sectional area.
As steam velocity is such a practical issue, it is reasonable that it could form the basis of a sizing method for steam pipes. For relatively short runs (less than 50m), velocities of 15 to 40 m/s are used in saturated steam applications.
