Hi everyone!
I am trying to specify relief valves to be installed at the discharge of dosing pumps (chemical injection at petroleum platforms). All pumps are for very low flow (from 6 l/h to 900 l/h) and high pressure (from 275 barg to 640 barg) and I think I could use non-ASME PSVs, like Swagelok, but my chief insists that we need to apply ASME VIII PSVs.
I understand that valves with ASME VIII certificate will be oversized.
Could you help me, please?
Thanks!
