Hi, I have a question regarding the hydrotest water. Is there any codes or practice we can follow in terms of the water used for hydrotest? How to prevent the potential corrosion issue? Thanks.
50 microns seems to be a rule of thumb for maximum acceptable particle size for hydro test water (at least for carbon steel). I have researched unsuccessfully (including Eng-Tips) the technical basis for this magic number. Does anyone know where the 50 microns come from? ... your feedback is much appreciated.
Dhurjati, DEP 31.40.40.38 seems to be a Shell document. Do you know how I can get it?; I searched the Internet for a download site and could not find any.
