(OP)
ASME B16.5 150lb RF, currently I am allowing these to be used for normal operating design pressure max. 6 bar/0.6 MPa. Our test pressure is 6 bar X 1.5 equals 9 bar/0.9MPa.
I want to know what is the maximum safe operating pressure that I can allow.

RE: pressure
From your hydrotest calculation, I assume the ambient operating temperature for the mentioned flanges, otherwise you would add the temperature correction.
Hence, your maximum operating pressure is 1920 kPa at ambient temperature.
