Hello to all;
We have a GRP underground pipeline for sea water transportation. Because of clash with another pipeline, a portion of pipe moves up and after a couple of meters moves down in the previous elevation, and therefore makes an air pocket in the line. Naturally we need a vent hole on the top of the elevated pipe for hydrotest. The question is: do we need this vent hole for venting of air before transportation of sea water? I mean can accumulation of air obstruct the pipe?
