Hi all,

During hydrotesting of complex piping how can we ensure there is no air entrapment in the system. Is Provison of high point vent the only solution?.Is there any other methods available to check air entrapment.with some calculation or pressure drop etc

Also can some one explain the problem with air entrapment and why is it taken seriously.

Another issue is Dew point- dryness of vessels after testing how can it be done.Can some one share their thoughts.Thanks.
