PVC Bends

[Alwayslearningelec]

These turns are obviously field made bends, correct? Well maybe not I do see a coupling on one of the bends.

Those look like field bends to me. And the way that they are "chaired", it looks like a duct bank that will be poured in concrete. Very nice work.

I'm not sure if they're factory made, but I see several couplings in each conduit.

Looks like some standard long sweep elbows within available deg curve, based on joint position and number of joints. Add to that some of the joints do look to be slight misaligned like trying to get the spacing aligned within the deg of stock curves, seen between the second and third chair up from bottom of pic.

With that rack and installation on a warm sunny day, I would probable just glue the lengths together and walk them around the bend, and securing them to the rack.

Top two are possibly stock elbows, and do have some couplings on that run. The bottom row looks field bent to me and is all bell ends for couplings from what I can tell.

Field bent or at least prefabbed for the application then brought to the site

maybe. 2 inch or less you can do that easier than for larger sizes. Might still need a little extra heat to help make it bend easier

Not saying that’s what those are but ATKORE makes a pvc conduit that is more flexible thank regular pvc. Of course it cost more.

That radius looks big enough to work with 4"....just make sure the glue is set and have a few extra lengths for leverage.

Is that the type with the foam core and inner and outer layers of PVC?

What is bell end for couplings mean. I though only bell ends where the conduit entered an opening( say an underground box). How does a bell end get used with a coupling for pvc? Thanks

 

[LarryFine]

Bell-ends are instead of couplings.

Oh ok I’m aware of that but they also sell end bells that you can put on the end of the conduit . My confusion sorry

I can’t remember how it’s made. A sales rep came out to a job a couple of years ago trying to sell us some. It was a good presentation.

I even think they make 20' lengths of gray pvc now.

They have for years. Very common to use them in duct banks.

AFAIK they are not listed, unless that has changed more recently.

Nice clean and large enough ditch. Don’t see that much.

Something I haven't seen for a long time is the old Greenlee motorized pvc bending oven boxes. You can stick a few lengths in depending on size of conduit and let the machine run and you will have noodles after a bit of time in that machine. It rotates the pipe while heating it. I don't know if Greenlee still sells that machine , but it was really handy for keeping up with the brickies on a jobsite .
