[MW:25179] Pipeline hydro test sectioning.


Does any specific requirement for hydro test sectioning method?
If pipeline is going more than 100 KM how do we handle the hydro test?
I suppose it is not possible to test one time due to the cost and time.

My question is as below;
1. The permanent flanges are required for sectioning for test? Or normally it is done by temporary flange?
2. If we need permanent flanges for test, how can I choose the location of flange?
