Is this mis-allignment at weld joint(pipe to pipe)?
If not above then as per your below mail "pipe line in the rack is not straight. they are going the way like snake"which is possible only when we make use of pipe fittings .Your process team would have already accounted for process parameter like pressure drop due to frictional losses and hence you need not worry for straightness of pipe

Subject: [MW:15360] Pipe Alignment tolerances as per ASME B31.3
Dear Experts,
We are going to erect the pipe in the pipe rack. The construction is erecting pipe, doing fit-up, and welding. But pipe line in the rack is not straight. they are going the way like snake. Our consturction code is ASME B31.3 process piping. I wanted to know what is the acceptance criteria for the straightness if the line pipe.
Please provide the reference.
