neumatic test pressure ASME B31.3

neumatic test pressure ASME B31.3

neumatic test pressure ASME B31.3

Our pipe will work at 350 psig of pressure and 543ºC. The material is A335 P9
The Hydraulic test is calculated as follows.
The pneumatic test pressure as it should be calculated?.
1. 1.1*MAWP*LSR or
2. 1.1*MAWP

Inclusion of LSR is doubt.
The doubt is; Is the LSR used in pneumatic testing?. If not used, integrity is not tested because the piping would stress much less than stress in operation.
