Re: [MW:17763] Technical Query : Small bores piping Pneumatic tets @ 170 bars

If pneumatic testing was cancelled then the client must sign a concession and it should then be supplemented with RT 100% not PT.

Suggest that carryout Hydro. if service requirement does not permit hydro, go for penumatic at MAWP not 1.3 times.

if Sec VII Div is code of construction, PT has to be done while performing penumtic

Dear experts,

 I have one doubt,

Construction code : ASME B31.1

 We have oil piping service line (small bore). According designers we should perform Pneumatic test @ 175 bars but for Safety matters  Pneumatic test is cancelled and client agreed to perform full PT (All socket welds connections).

I am asking if they're other way to confirm this issue ? PT is sufficient ?

Thank you.

Regards.
