I don't think you'll ever know for sure. What are you planning on using it for?

the dimensions suggest that this pipe is regular ol' 3" SCH. 40 PVC pipe

You can't be sure what it is, I would assume that it's not pressure rated so you don't get killed/maimed!

uh, ok um this pipe is prolly way better than sch 40 seeing as its hella heavy and it is TWICE THE WIDTH of regular sch40 pipe. If you don't know, please don't post, but if you do know how to look up the certification number please tell me.

ps. it has 1/4" walls. o yeah, look at the real picture of the pipe not the crappy little thumbnails.

What do you mean, twice the width of regulare sch 40 pipe?
It's dimentions are exactly what one would expect.

Looks like it's solid core too, although it can be hard to tell in pictures.

I didn't find anything on the certification number though...

well on my 2" sch 40 pipe, the walls are 1/8th of an in while this one has wall that are 1/4' of an inch... plus its heavy.

It's not anywhere near twice the thickness of Sch.40. The minimum wall thickness of 3" Sch.40 PVC is .216" ASTM D1785.

EDIT:

3" sch. 40 min. .216" wall
2" sch. 40 min. .154" wall

Bigger pipe = Thicker wall.

Also the average weight of 3" sch.40 PVC is 1.488 lbs. per Ft.

well i guess this is a simple mistake caused by lack of experiance, sch is not a fixed value, is there a formula or something?

sch is not a fixed value, is there a formula or something?

Yes, it is! Here is a chart of Sch. 40 PVC pipe dimensions up to 24"

Nan, those guys at the factories just kinda wing it.

lol yep there's your problem

ok, thx. I realized after I posted, that the wall thickness should be more than the 2", but it still is unusually thick.
So, does anyone know what type it is?

There is a picture of the serial number but I don't know how to enter it into the csa database. if anyone knows how that would be great

No, it is not "unusualy thick".
It's called <i>min</i> wall for a reason; that is the thinnest the wall can be.

4" pipe has a min wall thickness of .237", yet my specimin measures .253"
That's a whole .016"!

.216" + .016" = .232"
.25" - .232" = .018"

Now, if you want to complain about a measuring error of .02" with a ruler, we'll continue to call you insane.
And personaly, looking at your picture, the pipe <i>does</i> look like it's a couple hundreths thinner that .25"
