Pipe question on roundness

[jonesy412]

Does any one know if there is a mill tolerance for the roundness of pipe, with the material being sa106 or sa53B and 30" OD x 30'-0" long with a .375" wall thickness?

Something this big we would normally roll, but with a spec of .010 roundness I though of pipe but can't find what the mill specs are.

Just wanted to say thanks for the wealth of information that I've received from this board.

Thanks again,

Tom

I believe that the ASME B31.1/B31.3 piping codes contain limitations on the out-of-roundness permitted in completed systems.
