At what pressure do low-pressure boilers operate for steam?

Low-pressure boilers that operate for steam typically function at a maximum pressure of 15 psi. This classification is important because it helps differentiate between low-pressure and high-pressure systems, which have different safety regulations, design requirements, and operational standards. In the context of mechanical codes, understanding the pressure classifications is crucial for compliance with safety standards and ensuring the reliability and efficiency of the boiler system.

In general, low-pressure steam boilers are widely used in heating applications and have specific parameters set to ensure they operate within safe limits. The labeling of 15 psi as the cut-off for low-pressure steam allows for proper categorization and regulation of the equipment. Other pressures listed, like 10 psi, 25 psi, or 30 psi, exceed the typical pressure for low-pressure systems, thus defining them as high-pressure boilers, which require different management and compliance strategies.
