Mech.Design, barg 14 / HV* * HV=half vacuum. Can someone help explain what this means? Does this refer to the design pressure under a semi-vacuum?

Don’t you have any friends to talk to? Does it mean that this device can withstand pressures in a low vacuum?

I guess that’s what it means – the overall force under semi-vacuum conditions~ It’s best to ask the designer about this; guessing wrong could lead to an explosion~

14barg is the upper design pressure limit of the container, at which point the container is subjected to internal pressure. Lower design pressure limit for the HV vessel, at which the vessel is subjected to external pressure.
