Re: [MW:30688] SET PRESSURE FOR PRESSURE RELIEF VALVE FOR HYDROTESTING OF POWER PIPING

Agree, for pneumatic tests the RVs are set at 110 percent of test pressure followed by reducing the pressure to 90 percent of test pressure and further reducing it to design pressure or operating pressure and go for the weld snoop test.
