Specified pressure a product is designed to withstand.
The pressure at which the system is designed to operate under normal conditions.
The pressure specified that is used to design a product. Normally given in conjunction with the design temperature to specify the material properties to be used. The design pressure is normally equal to or greater than the operating or Working Pressure.
The maximum continuous operating pressure as designed by the manufacturer. ( 020)
The sum total of the desired head pressure added to the total of all pressure losses. A stated pressure indicating the minimum pressure required if the system is to operate properly.
The pressure used in the design of a vessel. It is recommended to design a vessel and its parts for a pressure 10% above its operating pressure.
The pressure used to calculate the thickness of the shell of the tank. Design codes require the design pressure to equal or exceed the maximum allowable working pressure or equal or exceed the test pressure depending on which code is applicable.
The maximum internal and external pressure limits that a pressure vessel can withstand, usually equivalent to 110% of vessel operating pressure.
Is the total pressure available to operate the irrigation system.
The pressure used in the design of a boiler for the purpose of determining the minimum permissible thickness or physical characteristics of the different parts of a boiler.
