The classification of low-pressure boilers typically falls within the range of 0 to 15 PSI MAWP (Maximum Allowable Working Pressure). This standard is established by industry regulations, such as those outlined by the American Society of Mechanical Engineers (ASME). Low-pressure boilers are designed to operate safely at pressures above atmospheric but below the critical thresholds that define higher pressure boiler classifications.

Understanding this classification is crucial for operators as it affects the design, safety precautions, and operational procedures required for the safe management of the boiler system. Low-pressure boilers generally serve applications that do not require high steam output, making them commonly used in residential and various industrial service settings.

In contrast, the other pressure ranges denote higher classifications of boilers. For instance, pressures from 16 PSI to 75 PSI categorize as medium to high-pressure boilers, which require more stringent safety standards and operational protocols due to the increased risk associated with handling higher steam pressures. This foundational knowledge is essential for anyone operating or managing boiler systems to ensure proper adherence to safety regulations and operational efficiency.
