Thank you for your interesy but what do you mean by (with a P)

Pick a pig (with a P) that will not hang by the internal beeds. Use a pig with an internal cavity and an electronic tracer for a long pipeline.

Take into account pressure due to static head of test medium even if you are using gas (air or nitrogen) for the hydrotest. Potential problems: If your test location is lower that the highest point in the pipeline, the highest point may not reach the minimum acceptable test pressure. Don't underestimate!

Under what ASME/? code are you testing the pipeline? B31.1/ .3/.4/.8 or AWWA?

Cheers, ET, PE.
