Re: [MW:30318] PSV set pressure during hydrotest of piping

Gentlemen,

During HT of piping, all the openings are to be blanked suitably, except test gauges mounted for pressure reading. Means you remove the PSV and blank off the opening.

Thanks & Best Regards,

Dear Experts,

As per B31.3 what is the PSV set pressure during hydrotest.

Please give expert opinion as there is no clause found in B31.3 for hydrotest PSV set pressure, PSV set pressure for pneumatic only prescribed.

Thanks in advance,

Manoj
