At what PSI and temperature does steam or heating media piping begin according to regulations?

The appropriate threshold for steam or heating media piping is established at a pressure of 15 PSI and a temperature of 250°F. This specification is crucial because it delineates when the piping systems are subject to specific safety regulations and standards that govern their design, installation, and operation.

At this pressure and temperature, the properties of steam and the associated risks inherent in high-pressure systems come into play, necessitating adherence to stringent guidelines to ensure safety and efficiency. Understanding this regulation is essential for professionals in the field, as it informs decisions regarding materials, maintenance, and safety protocols for high-pressure piping systems.

By recognizing 15 PSI and 250°F as the benchmark, practitioners can better navigate the requirements and standards that apply to their work with steam systems, ensuring compliance and the safe functioning of heating media installations.
