Whats up guys. Listen I come to this forum to pick peoples brains and see if I can come up with different things . So thanks in advance.
Heres the story I have done a ton of slab work but I have recently come across a PRIMA DONNA concrete company that just wants the fast way out.
We have a woos of a Superintendent so to get right to it
I lost 12 pipes had to cut off flush to new concrete.
Does anyone know if they make a Die head for 1 inch conduit that would thread those stubs if I chipped them back? Obviously I have the problem of the way the die has to fit onto conduit.
Ive tooyed around in my head with cutting off the adapter section of die and possibly setting into a coupling.
Any ideas brothers? They wont accept compression ( Unbeleivable)
 
Sounds like you're out of luck unless that conduits are far enough apart that you can get the threader head onto them after they're chopped out.

Not even close to the wrong place as Infinity implies. I actually know the EXACT product to use. go to here:

http://www.spproducts.com/IP15.html

and here http://www.spproducts.com/ for their home page. They have many wonderful innovative products. I strongly suggest you look around their web site. For this specific application the link I included is a drill/reamer with various fittings (GRC threads, bell ends, compression or set screw EMT) to transition for flush concrete to above grade. It is actually designed to do what you concrete person did on purpose. I haven't used them because the price point vs. the labor savings hasn't made sense in Florida but I stay aware of these products. You can contact them directly, and they will help you out, but they sell to you local supplier. Good luck. Let me know how they work.



Oops, I actually see where you may be implying that it is GRC at the slab level not PVC as the above tool works for. If that is the case, are they nipples or are they the ends of elbows? If they are nipples, just core slightly larger than the OD and unscrew them.
 
I don't know how far apart the pipes are, but the set up with the least amount of space would be to use a 1" die with a thin wall, deep well socket that fits over the die. This, of course, after enough concrete has been chipped away, which would mean about an inch or a bit more to get a 3/4" of thread.

Edit to add: I don't know if you realized it, but I was talking about using a hex die like this:

No clue how its setup but...

Why no compressions? Could do some late nights use em and then pour a concrete kick plate to cover up the fittings saying you wanted to fix the messed up concrete...

Edit: Will they not allow compression's cause of a hazardous area? IF SO you bury a concrete tight compression fitting in concrete then its legal cause its not the first fitting out of the ground, at least that's how id try to sell it...

There are so many red flags with the OP's project, it sounds like whoever is running that project needs to be fired. 10 minutes ago. I have never heard of a concrete crew cutting conduits off flush just so they could pour and finish some flatwork with no obstructions in their way. Anyone that allows a concrete crew to do that, when they could have just as easily told you (the electricians) to flush their conduits out with the slab finished height right from the start, is clearly unorganized and inexperienced. We had a job a few years ago that required all our rigid conduits flushed out with the top of concrete. We used a rigid coupling with a penny plug in it. Yes, it took longer, we set them with a laser and grade stick, but they weren't that difficult to uncover later.

Since the OP sounds like he's on his own to fix this, this is the route I would take. Chip some concrete, use a hex die with some good cutting oil and get it done.

If the stubups are nipples screwed into factory 90's, he may be able to unscrew and replace the nipples if they aren't too long. For our stubups, we always try to use nipples with 90's just for this reason, rather than bending them out of one piece of conduit.

Or course, don't forget to then backcharge accordingly for the stupidity and pain and suffering you've endured due to others.
 
Are they spread far enough to get a 12r die on? If so turn the die with offset pipe wrench. The offset allows you to turn the die down in a hole. You use the pipe wrench on the part that holds the dies in the 12 r head. Ive done this before, several of my dies are chewed up from pipe wrenches being used in this manner
