Our pipe will work at 350 psig of pressure and 543ºC. The material is A335 P9
The Hydraulic test is calculated as follows.
1.5*MAWP*LSR
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.
