What does it mean for a boiler to be classified as "low pressure"?

A boiler classified as "low pressure" refers to specific pressure limits that distinguish it from other classifications. For steam boilers, the threshold is set at operating pressures below 15 psi, while for hot water boilers, the limit is below 160 psi. This classification is significant because it determines the safety standards, materials used in construction, and operational protocols.

The distinction between low pressure and other categories is critical for proper system design and management. Understanding these pressure limits helps ensure that boilers are operated safely and efficiently within their designated parameters. It allows operators and maintenance personnel to follow appropriate guidelines for inspection, maintenance, and operation, thereby promoting safe practices in boiler management.
