What is the pressure requirement for a system using utility street steam?

Utility street steam is commonly provided at standard pressures and temperatures that align with the needs of various industrial processes. The correct answer reflects a pressure of 200 psig at a temperature of 413°F, which is a typical operating range for utility steam systems. Understanding the typical specifications of utility street steam helps ensure safety, efficiency, and compatibility with equipment designed to operate within this range.

Specifically, the pressure and temperature combination provided in the correct answer generally allows for effective heat transfer and meets the requirements for many steam-driven applications. Maintaining this pressure and temperature ensures that the steam remains in a superheated state, which prevents condensation in the delivery system and improves overall efficiency.

Furthermore, the other options present higher pressures and temperatures that are less common or potentially push the operational limits of typical utility steam systems. Systems operating at higher pressures may require specialized equipment and should be used only when necessary for specific industrial applications. Understanding these specifications is vital for ensuring safe and reliable operation in facilities utilizing street steam.
