[MW:9946] Pneumatic Leak Test

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,
