Pneumatic test system volume

[Imran.Idris]

We are going to perform pneumatic test of synthesis gas loop at 3000 Psig and the volume of the whole loop is 360 cu. m (12713 cu. ft). I want to know
1) Is it safe to pressurize this big loop in a single portion?
2) If yes! then what precaution should we take to carryout this test?
3) If no! then what should be the maximum volume that can be tested in a single go at 3000 psig?
4) Are there any standards for system volume calculations for a given pressure available?
Thanks in advance
Regards,
Imran

1) Safe with precautions
2) Estimate the stored energy, safe distance and comply with that. Get the whole site evacuated.
3) I haven't seen any limitations in any code standard. Calculate the stored energy and safe distance and present to your management. See what they say.
4) Some material in ASME PCC-2 has been given regarding pneumatic testing. Look into that which may help you through.

Go to the following link also, it will help you in estimating stored energy and safe distance.
