What is the term for the pressure specified by the boiler manufacturer as a criterion for design?

The term "design pressure" refers to the maximum allowable pressure that a boiler is designed to withstand under normal operating conditions. This specification is provided by the boiler manufacturer and is critical for ensuring safety and reliability in operation. The design pressure accounts for various factors, including the materials used in construction and the intended application of the boiler.

Having a clearly defined design pressure helps engineers and operators ascertain the safe operational limits and aids in the selection of safety devices and maintenance schedules. It also influences the overall engineering and design processes to ensure the boiler can handle the required workload without risk of failure. Understanding this term is essential for maintaining safe and efficient boiler operations.

Other terms, such as operating pressure, refer to the actual pressure at which a boiler runs during normal operations and may be lower than the design pressure. Test pressure is typically a higher pressure used during the testing phase of the boiler to ensure integrity and safety before it goes into service. Safety pressure refers to pressure limits concerning safety relief devices but is not related to the design specifications provided by the manufacturer.
