What is the hydraulic test value in this case?
Thread Content
The vacuum vessel is designed for a pressure of -0.1 Mpa; usually, hydraulic tests are conducted at a pressure of 0.125 Mpa. But today, an experienced engineer suggested that a water pressure of around 0.3 Mpa should be used for the tests. I’m not sure what the standard is in this regard
Don’t listen to rumors; they’re not true. Then you didn’t ask him for the reason at that time?
Aren’t there standards? Just follow the standards. What anyone says doesn’t count.
0.125, if calculated as 0. 3You need to verify it.
I wonder if your pressure gauges are that accurate? It’s usually two decimal places, I guess.
