Regarding the nameplate issue
Thread Content
The drawing usually shows the operating pressure of the medium, while the nameplate on the new pressure gauge indicates the maximum allowable operating pressure. How to engrave a nameplate. Still convert. How to convert.
If it is a pressure vessel, you definitely need to provide a strength calculation document (SW6), which includes an item specifying the maximum allowable working pressure! Maximum allowable operating pressure = = 5.62700
In design work, the maximum allowable operating pressure is generally not specified; this value represents the minimum of the maximum allowable operating pressures for each pressure-bearing component of the container, and it is difficult to determine. The new capacity regulations are quite difficult to implement.
The maximum allowable pressure, which is determined after the material has been selected and then recalculated, has been taken into account; in most cases, the operating pressure is used directly. The design pressure is not suitable for use as the maximum operating pressure, and our inspection team didn’t raise any objections either
Equipment equipped with safety accessories and that requires a gas-tightness test must indicate the maximum allowable operating pressure.
It is generally not necessary to write it down; it seems that it is required to provide this information for vessels that need to undergo airtightness tests and those equipped with safety accessories. Usually, this value is similar to the design pressure, as it is very difficult to determine the minimum of the maximum allowable working pressures for all the pressure-bearing components in the vessel.
It’s not the maximum allowable operating pressure, but the highest allowable operating pressure. According to the operating pressure at design time.
