Half pieces of PVC
 

I need some 3" or 4" PVC split long ways. Is this available commercially,
or will I have to do it on a table saw? About 80'.

Never seen it for sale.

Note that when you slit it on the table saw the kerf will close to due
the release of residual extrusion stress.

More noticeable on larger pipe (like 6").

Also the two cut pieces will no longer be "round", the cut edges tend
to "flare" to straight / lose their curvature.

What about half round gutters? Too flimsy? Maybe double 'em up?

I have ripped the grey pvc on the table saw and recently using the HF multi
tool using the circle blade.

The multi tool though slower did a far better job.

With 80' to do I think I would revert to the table saw and try to rig a jig
to keep each section flat and straight during ripping ( it has a tendency to
roll or twist).

@AEM one time I was making 3/4" slip on sleeves for a cable line that went
through a flower bed. The last time I was making a protective cover for
physical protection only, of an older electric SE over a patio.

I would make a jig that was about 2' long, the width of the pvc, and with
a top that is just higher than the blade height. Then you could hold it
on the table and feed it through. with it 2' long, you wouldn't have to
hold it above the blade. (yikes)

That would work if the blade is high enough to cut the pipe in one pass. If
not, you have to get a tad more sophisticated. I'd make a jig like you
mention for the first cut. Then I'd take a strip of metal and bend it 90
degrees to act as a guide while putting the pipe through on the second pass
that splits it. The guide can be ahead of the blade and would keep the
tubing from turning as you push.

I did this ONCE before, and used a band saw. Boy, howdy, did I learn a lot.
Don't ask. This time, I think I'll get it pretty close by building a jig,
and putting extensions on the sides of the saw to support it, and keep the
pipe oriented. It doesn't have to be perfect, just pretty good. They are
going to be gutters to catch the vertical fall of water from spraying the
outside walls of the container. The roof will have regular guttering, and a
pal of mine will come in and make me one 40' piece out of coil.

For eighty feet of pipe, it sounds like time to build a jig.
If you have a band saw available, that sounds like a good
way to split.

What are you building? Feeding trough for a barn full of
chickens?

the release of residual extrusion stress.

More noticeable on larger pipe (like 6").

Also the two cut pieces will no longer be "round", the cut edges tend
to "flare" to straight / lose their curvature.

Or close up.

I did this with a "Pool Noodle" from WalMart. A PoolNoodle is a four-foot
cylinder of foam rubber with a 1/2" hole through its length. I used it to
insulate the high-pressure line from the A/C condensing unit to the outside
wall. A similar piece of insulating rubber from the box store costs about
$8.00. The PoolNoodle was eighty-nine cents. Plus a rip through the saw.

Anyway, when ripped, the slot did not stay open, it closed up.

'Course this has absolutely nothing to do with PVC, I just felt like making
this a better world.

A common trick- I see slit pool noodle sections used as pads on roof
racks and such all the time.

A bandsaw would be my first choice.

I'd set the pipe along side a 2x4 and then hot glue it in a few places
along the length.

Oooh! Good idea about attaching it to a 2x4. That way it won't rotate.
