What is the maximum operating pressure for a low pressure steam boiler?

The maximum operating pressure for a low pressure steam boiler is typically defined as 15 psi. This standard is established to ensure the safe and efficient operation of low pressure steam systems. When steam boilers operate at pressures above this threshold, they shift into a different category, which requires adhering to more stringent regulations and safety measures.

Operating at 15 psi allows these boilers to produce steam effectively while remaining within a safe range that minimizes the risk of accidents or equipment failure. Low pressure steam boilers are commonly used in applications such as heating systems and industrial processes, where elevated pressures are not necessary.

Understanding this limit is crucial for those working with steam systems, as it helps maintain safety standards and ensures compliance with industry regulations. Familiarity with these operational boundaries supports both effective maintenance practices and adherence to safety protocols.
