    Piping subject to vacuum should be designed for a negative pressure of 100 kPa (1 bar) unless a vacuum breaker or similar device is provided, in which case a higher design pressure may be approved. The value of the design pressure to be used should include the static head, where applicable, unless this is taken into account separately.

  • What does "FV" mean in design pressure? - Boiler and Pressure

    The meaning of "4.5 MPa/FV" is that the pressure vessel or similar component is designed for a pressure of 4.5 Mega Pascals (gauge pressure), or Full Vacuum conditions. One Mega Pascal = Millions of Pascals. One MPa (gauge pressure) = 145.03 PSIG. The term FV means Full Vacuum, generally taken as 1 Atmosphere Pressure External to the vessel, with zero absolute pressure inside, equivalent to 15 PSIG External Pressure.

  • Evaluate pressure drop in vacuum systems

    Pressure DropOperating Demand Created by Pressure DropLeaksReduce The Pressure LossResultsWhat is pressure drop in a vacuum system? The idea of pressure drop in vacuum systems is similar in concept to pressure drop in plant compressed air systems. Pressure drop is the difference in operating pressure from the supply point to the use point. In compressed air systems, pressure drop is measured in psid, which means pounds per square inch differential. Pressure drop can be used as a measure of pressure drop in vacuum systems as well, but it is much more common to use inches of mercury as unit of measure. Table 1 illustrates some of the common pressure units used in vacuum and how the scales compare with one another. Note that the top of the table represents atmospheric pressure and the bottom of the table represents perfect vacuum. Also, note that there are two scales that use inches of mercury. Finding the pressure drop in a vacuum system is a simple procedure. First, measure the vacuum at the inlet to the vacuum pump using a reasonably accurate vacuum gauge. Then, using th...
