Does a 3" conduit typically have a 3" outer diameter?
Thanks.
Thanks.

RE: Conduits
3" trade size = 3.090" ID and 3.5" OD
RE: Conduits
SCH. 40 pipes that we use structurally are same way.
Thanks.

RE: Conduits
The same dies are used to thread conduit as are used for schedule 40 structural or piping. The couplings are different and may be marked EC.

Only the size is the same. Conduit is made from lower grade of metal. Pot metal, old tin cans, fords etc) and is seamed. I have seen a person who tried to make a temporary air filter out conduit and some sanitary napkins. The pipe opened along the seam like a zip lock bag.
IT 's also very hard to bend black iron pipe in 3/4" and 1" size with a hickey. Be very respectiful of someone who can.
RE: Conduits
Do you remember when the characteristic of rigid conduit went from very soft but not uniformly so to very hard? The new conduit rendered "One-Shot" hydraulic benders obsolete almost overnight.

RE: Conduits
ps: We can still buy One-Shots, but we can't bend most conduit with them. They are great for aluminum rigid conduit. Actually, I haven't tried for years. Not much call for rigid conduit bending skills anymore.

RE: Conduits
We use it on long straight runs because it's easy and lighter. When we get down to termination points where you have make some bends or offsets we switch to rigid.

I'm glad to hear that softer conduit is still available somewhere. BTW, 1 inch seemed to be the worst for kinking.
