RE: Hydrotest vent and drain [adr][adr]

Let me put on my process safety hat here: Do not try to use air or steam pressurization as a substitute for a hydro test!! A hydro test is used because it is safe in the event of a failure (and why are you testing in the first place, but to check for failure).

Subject: [PipingDesign] Hydrotest vent and drain [adr][adr] Importance: Low

Dear members;

Is it true that vent and drain are needed at every high and low point of piping if water is used for hydrotest? what if air or steam are used?

Can someone explain the general procure about how to use them in the hydrotest?

I know these question seems too junior but I do have confusion on it. your response is appreciated.

Thanks
Robert Liu
