hydrostatic testing of pipelines
(OP)
I am in the process of pressure testing an HDPE pipeline that currently contains water and i'm sure a certain amount of air. Is it imperative that I expel the air first? and why. How will it effect my test if air is left in the line. Thank you

The main difference is that the HDPE suffers from creep during the application of the test pressure. This is compromised by air in the syste. The test procedure is aimed at ensuring that you measure a pressure rate to reflect the creep and that all the air has been expelled.
