So, acc. PED Article 3, p.1.1 adequate temperature for 0,5 bar...
"Vapor pressure for water at 82°C is not > 0,5 bar(g), in that case water would boil at a temperature less than 82°C."
Do You mean, when vessel is closed ? What of it ? When container is completely filled with water and when we increase temperature above 100°C(e.g. heater), pressure will also...
Hello
I've found problem with classification of the pressure vessel containg oil (flammable -fluid group I, flaspoint below TS) with TS=200˚C, PS= 10 bar (g), V= 500 l.
PED Article 3, p.1.1
If a fluid has a vapour pressure at the maximum allowable temperature of the equipment of greater than...
