I dont know of any such beast. But I would think that a wall thickness min, of which there are requirements, would be an effective concentricity criteria nonetheless.
If it can only be so thin, and certainy won't be too thick, you essentialy have some semblance of concentricity.
Do you have a concentricity problem with stuff that thin?

i have a difference of approx .03 one thickness is .160 and the other side is .128 correct me if im wrong but i think the wall spec is no less than 87.5% nominal wall thickness.

Mike,
I'm looking at a pipe chart here that says nominal for Sch 10 5" is .134". In which case 87.5% would be 117".
