What is considered the maximum pressure of a Low Pressure Steam system?

In the context of steam systems, a Low Pressure Steam system is defined by the maximum allowable pressure it can operate at, which fundamentally influences design, safety, and operational practices. The maximum pressure designation for a Low Pressure Steam system is capped at 15 psig. This distinction is important for various reasons, including regulatory compliance, equipment specifications, and operational protocols.

When steam systems exceed 15 psig, they transition into the realm of Medium Pressure Steam systems. Operating pressures categorized beyond this threshold often require adherence to additional safety regulations and standards. Therefore, 15 psig serves as a critical benchmark in classifying steam systems and understanding the corresponding requirements and characteristics tied to low pressure applications.

Understanding this definition is essential for professionals in the field, as it impacts system design, maintenance, and safety protocols within steamfitting practices.
