Saturated Steam Table

TECHNICAL DATA

The following table presents basic thermodynamic properties of saturated steam as a function of absolute pressure. The data may be used as a technical reference for preliminary calculations and equipment selection in steam systems, including steam traps, control valves, pressure reducing valves, safety valves, condensate lines and heat exchange applications.

Use of the Saturated Steam Table in Equipment Selection

Saturation temperature, steam density and latent heat are key reference values when selecting or checking equipment for steam and condensate systems. They are commonly used during preliminary sizing of steam traps, control valves, pressure reducing stations, safety valves, heat exchangers and condensate return lines.

Typical Applications

Calculation of heat load in steam heat exchangers, coils and process heating equipment.
Preliminary steam trap selection based on operating pressure and condensate load.
Verification of saturation temperature before and after pressure reducing stations.
Support for steam valve selection according to pressure, temperature and flow conditions.
Estimation of steam density for flow rate and pipe sizing calculations.
Evaluation of condensate recovery and flash steam conditions.

Important Note

The values in this table are intended for technical guidance and preliminary calculations. Final equipment selection should always consider actual operating pressure, back pressure, condensate load, pressure losses, body material, connection type, applicable standards and installation conditions.
