Re: [MW:9955] RE: 9951] RE: 9946] Pneumatic Leak Test

this is usual to found leaks from flange joints and normally it will perform by commissioning teams with 5 bar pressure.

Hi,

 

We can go ahead with the least pressure and can test.

Take care for any accessories / attachments / fittings / filters / are in loop and will be in problem with the pneumatic test.

 

 

But, after doing hydro test in each individual sections why client is requesting to do pneumatic test?

 

 

Thanks & Regards

Hi there,

 

Construction Code: ASME B31.3

 

We have assemble a module for an offshore rig. The clients wants to do a Pneumatic leak test on the whole assembly of pipings. The pipes spools are somehow connected to each other and have been hydrostatic tested on different pressure. Now since the  assembly have different test pressure as per design, do we have to do the pneumatic test taking the least test pressure?

 

Please give me a reference from the code.

 

 

Many thanks,

 

Larry Zarate
