In general Practice it's allowed to do Hydro test (1.5or 1.2 times design pressure based on design code ) one time only.Retest due to any failure joints will allow but you can not keep on doing retest rather you have identify the causes of failure.

Hi.
If the piping system getting fails in every test. Howmany times we can
do the hydro test for the same piping system?
If we are doing the the hydrotest, we are weakening the pipe material.
So, Howmany times the same system can be allowed to retest?
