What is the safe working pressure usually designated for low-pressure boilers?

Low-pressure boilers are typically defined by their maximum allowable pressure, and the safe working pressure for these systems is primarily designated as 15 PSI or less. This classification is significant because it demarcates a specific range where safety regulations and operational protocols apply, ensuring that the systems operate within safe limits.

Boilers operating at or below this pressure are subjected to different regulation standards than those exceeding it, which is critical for safety and compliance. Knowledge of this threshold helps in the proper selection, installation, and maintenance of low-pressure boiler systems, as well as in understanding the operational limitations and safety precautions required for their use.

Choosing a working pressure above 15 PSI would categorize the boiler as a high-pressure system, which imposes stricter controls and additional safety measures. Thus, recognizing that low-pressure boilers are limited to a maximum of 15 PSI is essential for anyone involved in boiler operation or maintenance.
