PSV Inspection Sch.
PSV Inspection Sch.
(OP)
Each PSV is planned to inspec every year.
If we design to have 2 PSVs are installed with 100% capacity(for on-line maintenance), one on-line, on-standby.Can we extend inspection schedule to every 2 yrs?
My idea is we can't, we have to inspect all PSVs as sch., but I can't find in API.
If u know what API part, pls inform.
Thank you

We also take into acount past history of use, previous inspections, age, other safety systems. We then use this data to set the testing period. For example, a sour fluid on a pulsating line set at 1000 psig that has opened at least once a year will be inspected every 6 months. A relief valve on a propane storage tank that hasn't open in the last two years will be inspected every 5 years (per ASME section VIII)

I mean testing, not inspection. I try to find that are there state about testing frequency of stand-by PSV.
I haven't seen in API 520,521,526..etc.
Are there in ASME 8, unfortunately it's lost from my office.
Thanks
