Container water pressure issues

When you perform a hydraulic test after the equipment is completed, do you drain all the gas in the pipes? It seems...
Generally, the hydraulic test after the equipment is manufactured is completed in the manufacturing factory. At that time, there are only water inlets and drains, and the rest are blind. On-site water testing is the same.
When blindly dying, can you ensure that the air in the pipe is emptied?
When doing a water test, one opening will be left for air purification, and the other openings will be sealed.
When doing water testing, a port will be left for air purification.
When doing a hydraulic test, a port will be left at the highest point of the equipment for purging air.
After the equipment is manufactured, the manufacturer will perform a hydraulic pressure test or an air tightness test as required. When doing the hydraulic pressure test, all the gas in the equipment will be drained. Generally, the highest port will be left as the exhaust port, and the others will be blind.
Yes, when doing the water test, a port will be left for air purification, and the other nozzles will be sealed.
During the water filling process, one of the openings is not closed, so of course the air can be discharged.
It doesn’t matter if you can’t finish it. ASME also has a water-air mixture pressure test.
