Hydrostatic and pneumatic test
Hydrostatic and pneumatic test
(OP)
Hi,
I'm working about hydrocarbon counting system and I would like to know the pressure level for pressure test (hydro and pneumatic). There are two cases:
1)Gas hydrocarbon:
Pressure Nominal: 100 bars, Class ANSI600
2)Liquid hydrocarbon:
Operating Pressure:60 bars
Pressure Design: 100 bars, Class ANSI600 (For component selection)
Particulary, for liquid hydrocarbon, should I carry out the pressure test as operating pressure would be 100 bars?
What do you think?

RE: Hydrostatic and pneumatic test
In the case of the liquid hydrocarbon, the fact that the normal operating pressure ( today ) is only 60 bars does not mean that it will never operte in the future at its desing pressure of 100 bar or at the relief vale overpressure case of ( 120 bar ?). The proof test is meant to show that the vesel is adqquate for the design pressure stamped on its nameplate- someday someone willcertainly operate it at the 100bar pressure. I would rather have it fail with hydrotest water than with a liquid hydrocarbon.
