fabricated pipe
(OP)
Does anyone know typical dimensional limits (minimum diameter, maximum thickness) for fabricated pipe?
Hg
p.s. Is there a better term to use than "fabricated pipe"? A web search on that term was a lot less useful than I thought it would be.

Regarding tolerances, I know that they have different tolerances, and I would imagine that they would be indicated on some code. A google search for 'welded pipe tolerances' produced quite a few hits

RE: fabricated pipe
For pipe larger than 2", the outside diameter shall not very by more than 1 percent. The minimum wall thickness shall not be more than 12.5 percent less than the nominal thickness.

Roughly what size are you needing?

Try asking again.
RE: fabricated pipe
I think I have what I need, though; if taking standard plate and bending it to form a nonstandard pipe were as standard a practice as my off-forum correspondent seemed to consider it to be, I'd have gotten a different set of responses.

p.s. Turns out it's worse than I thought--required thickness is 1.75" (45 mm) with 16" OD. Last time I saw anyone try to bend that thickness to that radius, it wasn't pretty.

RE: fabricated pipe
I'm dealing with two parties here--Party A insists on the dimensions, and Party B thought maybe making pipe from plate would be the solution. Neither Party B nor I have yet found a pipe spec meeting those dimensions.
So the current plan is to find out from Party A what solution they had in mind, since they're the ones saying that those dimensions are achievable.
Oh well. Thanks y'all.

I mentioned the quantity. When you get into something like that, they're going to be forming & welding one can at a time, and if you need a mile of it, it might be a problem. If you just need a few feet or few dozen feet of it, it would work.
