I have always used I.D. for pipe less than six inches in diameter and O.D. for anything over.
Not the way the old timers did it around here.?ÿ I heard told they would go to the dump and find discarded length of pipe and bend them back and forth till they broke, i.e. pinch pipe.?ÿ But I now know that a modern guy might use a shear press and get a "pinch pipe", thank you.?ÿ?ÿ
The whole point of calling size is to leave bread crumbs for others to follow in our footsteps and be assured they find the same mark in the ground, so Oregon Law says "detailed description of monuments found and set".?ÿ Jp?ÿ
I was under the impression all pipe sizes were measured by inside diameter.?ÿ Maybe I should start specifying ID if that's not the case.
I was under the impression that EVERYBODY knew that a 2x4 was 1-1/2" x 3-1/2". Litigation has shown to the contrary.
I was of the impression that EVERYBODY knew coffee was hot. The McDonalds coffee was hotter, and litigation has shown that it is not hot, but HOT!!
People today, don't know left hand, right hand. You tell them "Turn right", and they reply, which way's that?
There are a few other things people today don't know. But, we aren't ....
Say, nice weather?
🙂
agree. One of the more successful surveyors from the past left behind a lot of pinched tops in my area. I??m happy to find them as they are almost surely the original corners. I label them EIPP and note EIPP in my legend as Existing Iron Pipe Pinched. No dimension is reasonable in these cases.?ÿ?ÿ
Our statutes on monuments are worded to reflect least dimension. That would imply outer diameter. Nearly all of our post and cap monuments fit over the post or pipe. Again this makes OD the pertinent dimension. If I take up plumbing I'll start doing ID.?ÿ
Like if it??s been beat on, and mushroomed out.
I recently recovered a pinched 2-1/4" pipe. We recovered a number of 2-1/4" pipes on the project and this appeared to be the same diameter. God only knows how you can pinch a large pipe like that. I just read some earlier posts. Again, thanks to those who commented on the history of the pinched pipe. It will take its rightful place on our code list!
But, I just use a box tape, with inches and fractions on one side, and tenths on the other.?ÿ
Do they make pipe gauges?
Maybe I should start specifying ID if that's not the case.
Makes sense to me. If I was a plumber I'd order a pipe using ID because I'd be concerned with fluid flow. I feel a surveyor should be concerned with how much pipe is in the ground. Therefore, I believe OD is more appropriate.
Fortunately, this doesn't come up very often for me as pipes are not commonly found.
I think for a long time surveyors have been cost conscious about the price of iron. You can almost figure out the age of a subdivision by what the original surveyor set. Nowadays, I think 1/2" or 5/8" rebar are preferred. I don't agree with surveyors around here saying they recovered a 1/2" IPC (Iron Pipe and Cap). Caps sit on top of rebar; plugs go in pipes.
A common trick was to divide up section of pipe by bending then over double, then back and forth until they broke off - rather than cutting them. This results in what we call a "pinch-top" pipe
Good history. I was unaware that this was done on purpose. How else could the pinched pipe that I recently recovered look so good?
Good point, but the true invert elevation has nothing to do with the wall thickness of the pipe. If you shoot the top of the pipe, measure down to the invert from there. The only reason I wouldn't shoot an invert directly would be for lack of rod height. A direct shot is always preferred.
Sometimes the end of the pipe is filled with a pile of rip rap or some other thing and a direct shot isn't possible though.?ÿ So we need wall thickness and diameter to subtract from the top of pipe shot to get the invert.
( In Buttheads voice...) Uhuhuhuhhhuh you said Shaft...uhuhuhuhhhuhuh
I don't get it.?ÿ What is an outside diameter??ÿ Do you mean circumference?
I'd have to agree with the left/right thing.?ÿ Directions with a bunch of lefts and rights is mind numbing.
It's seems, at least to me, a lot easier to use the cardinal directions - with more choices than just left and right.
That's some of the best sense I've heard in awhile.?ÿ Thinking of some of the bar ditches locally that haven't been maintained since the Cenozoic Era and the silt/flow line can reach the top of the culvert.
If you want to suck the very life from a budget, dig out every flowline of all the; muck, old shirts and pants, bizarre plant root systems, old tires, abandoned silt fencing, plastic bags .. and make sure you're not tieing the female end of a pipe. Only to discover that there really isn't any rhyme or reason to how the various pipes were established for elevation over the years.

Not a really interesting story about digging around a chain link post in a historically-undermonumented-neighborhood when I heard what I thought was a dog running up on me.
Spun around and there wasn't a soul. Two guys talking in a driveway 600-800' down the road. still digging when I heard the dog again, turned around and nothing. Done digging around the fence post, and walking off when a little momma dog came crawling out of the nearby culvert pipe. Scare the heck out of me.
I was of the impression that EVERYBODY knew coffee was hot. The McDonalds coffee was hotter, and litigation has shown that it is not hot, but HOT!!
The coffee from the local McD's is highly variable, in temperature (ranging from room to thermo-nuclear) and taste (ranging from mouse-pee to skunk) but thankfully not variable in texture. Consistency eludes the staff. Just last week I got given one that I'm sure contained the ingredients in their plasma state, then next time I get firmly told to hold the cup very carefully because it's "very hot", when in fact it was actually stone cold.?ÿ
This McDonalds coffee case has long since passed into the realm of urban legend. I encourage one and all to look into the actual facts. It's an easy google. Those facts actually make sense.
The events occurred while Starbucks was still just an obscure coffee house in Seattle.?ÿ Drive thru's were a relatively new thing. And McD's was serving coffee just a few degrees off boiling in flimsy cups with lids that popped off easily. Not like what we know today. The plaintiff was far from the first person to be injured by it and spent extended time in hospital.?ÿ ?ÿ ?ÿ?ÿ

Mr. O,
Just curious. Is that dividing going on at the manufacturer or pipe supplier's end?
Or are you saying that a crew carries a section of iron pipe and then "bends the appropriate length of pipe for each corner"?
I can only imagine the forearms required to pull this off. Certainly not one of the tools in my "toolbox".
