There is a PVC drain on the floor of the laundry room. I inserted a 1
1/2" pipe in it but the hole is slightly larger. I think it is about
1/8" larger. Its OD is slightly larger than the OD of a 1 1/2" pipe
coupling. There is no PVC pipe whose size is between 1 1/2" and 2". You
either have 1 1/2" pipe or you have 2" pipe. There is no 1 3/4" PVC pipe
and it would be too large if there were such a pipe.

So, what is the size of this drain?

Perhaps somebody mixed in CPVC tubing-dimensioned material instead???

Where is this located geographically?

Can you post a picture or two with tape measure in appropriate location
for visualization?

Or maybe more likely the "drain" isn't just the end of a PVC pipe but
some drain attached to the pipe, in which case it could be any size opening.
I don't think the drain in the floor of a laundry room typically just
ends with PVC pipe.

!.5" PVC has an OD of 1.9". It sounds like you have nominal 2" ID
pipe. If it is thinwall, the ID will be a bit larger than schedule 40
because the OD is still the same.

That is also pretty standard for floor and shower drains.

True. The couplers, etc are all the same regardless of schedule
40 or 80.

False. The fittings are all the same size, and they fit on the outside
so the ID is what varies from thickness to thickness.

Not true at all or they could not use the same fittings.
That starts being true when you get up to 3" and over but the OD of 2"
and below is the same as schedule 40.
I have some in the garage I can take pictures of if you don't believe
me.

.... or schedule 200 the real thin wall stuff.
4" and up is totally different. The thin wall is smaller inside and
out. (different fittings)
Again I have some of each in the garage.

The following is the measurement I took with a ruler. It may be off by a
little.

1 1/2" pipe: OD 47 mm

1 1/2" coupling: OD 56 mm, ID 48 mm

drain: OD 60mm, ID 55 mm

This drain is an 90 degree elbow. There is another drain next to it. The
second drain must be a T. Its size, by eyeballing, is same as the elbow
drain.

All of this divisiveness has us all on edge. We all agree. up to 2"
the OD is the same ID changes and thin wall drain pipe starts being
another breed of cat after that.
For the OP. That is 2" probably schmo 40 once you get past the flange.

Oh no, not that commie metric thing ;-)

In real life "roughly" 47mm is 1.85 in and close enough to the nominal
1.9 inches to say "pot's right" ;-)

See it works in the other 95% of the world too ;-)

Where in the world is this located? It also seems rather odd that a floor
drain would just be a 90 deg elbow, with no provision for a cover of some
kind to keep debris out. That's why I thought it could be some kind of
drain, in which case, it could have any dimensions. It still could be
that, is there any indication it was made to accept an insert that serves
as a strainer, for example? And what is the objective? I assume this
is in a concrete floor? What are you trying to do with it?
