Pneumatic Testing Steps of Pressure Vessel per ASME Section VIII;

Pressure testing using the Pneumatic Test according to ASME Section VIII has the following steps:

1. Step 1 to increase the pressure to 50% of required pressure test ( Test, Pressure ).
2. Gradually increase the pressure in steps, stepby 10% of Test pressure until equal to Test pressure.
3. Test the pressure by keeping the pressure at Test pressure fora period of time.
4. Reduce the pressure to Test pressure divided by 1.1 in order to inspect the leak of the Pressure vessel using Visual method.
5. If no leakage is found, reduce the pressure.Complete thePneumatic test
