Re: [MW:17735] Technical Query : Small bores piping Pneumatic tets @ 170 bars

I think your client must have come from another planet how on earth can you confirm the integrity of the line where a pressure testing of 170 bar is required by simply doing a Pt on the weld joints?
Not at all you need to replace the pneumatic test with HT that is the only acceptable method

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.
