Cutting plastic (PVC pipes in half)

Hello.
I have a question, what would be the best to cut a 6 m PVC plastic pipe from the water (pipeline). I plan to mark it in half and cut it on 2 sides to make 2 gutters. The point is to make the gutters quite evenly cut. Then I would like to set up these 2 gutters on the cowshed, which is 11 meters long.

If you want it nice and smooth, use a heated resistance wire (electric cutter). And if quickly and in any way, then with a grinder, the so-called with a square.

Will this gutter be too heavy?

Panties over the head. There are ready-made gutter profiles and they should be used. I wonder how you intend to accurately mark the cut lines on the 6m pipe. First try to do this, then ask how to cut.

An angle grinder is probably the worst that can be. Preferably with a jigsaw, but I can't imagine how to evenly cut a 6m long pipe along the length.
I myself would rather think about the use of a circular saw - the so-called country.
The author of the thread writes about the gutter to the cowshed, so I conclude that he lives in the countryside, and there should be no problem in villages with access to the country.

With the band saw you can cut both sides at once, but the problem remains of guiding it to be cut straight.
A better solution is probably to sell the pipe and buy a normal gutter.

Exactly.

The point is that he has 20 of these pipes, the cowshed is old, he does not plan to buy new gutters, and I have pipes and I came up with the idea that I would use them. As for the selection, I think a thin string of powder and they saw them evenly, as the lines on the floor at the construction site are marked. And my hooks are large, made of a thick flat bar, so it won't bend. Also 2 pipes and I would have gutters on 2 sides and it would be connected, only in one place.
As for the resistance wire, I also thought about it, or about flattening the copper tip from the soldering iron to a flat and trying to cut it.

Only the floor is not round ... Here you have to mark two lines on something that is round. I bet what you want you don't do it equally.

The stench of poop and you might end up in the spring and no one knows what will come of it.

Give it up, because you will do something wrong and you will not have a gutter ...

I will try to cut tomorrow, see what comes out, if it comes out well, I will post a photo. As for the selection, I have already tried and it turned out well, and a few millimeters of difference does not matter, as I have already written, it should be for the cowshed.

You need to make a guide for the pipe (a tray made of boards) and attach it to the table top of a circular saw or other (or attach a "rubber band" to the guide, if there is nothing else ...)
At the end of the pipe, attach a handle, also made of boards, to prevent it from turning. You will need an assistant who will hold the handle in your hands and push it while you handle the saw.

There is one more possibility, but it depends on the pipe and exactly how it is made. It might not work, especially since it's a long pipe. Well, some of them can be broken evenly in half along the seam. I discovered it by accident when, while carrying something heavy, I stepped violently on one lying on a hard surface In this way, I obtained over a meter of gutter in two pieces.

PS
Me + something heavy is probably about 80 kg, so that it would not be that 450 kg

After cutting the pipe, you will get two profiles, something like gutters, but they will be much "shallower" than the produced ones, they are fuller and more closed, and their wounds are strengthened and wrapped.
The friend's gutter will be very slack, weak shallow, water flowing from the roof will be thrown from it, snow, icicles will easily damage it, they will break it.
You will get better and the effects will be mediocre and for a short time, even none.
You want cheap, buy an ordinary galvanized sheet gutter, solder it, paint it after two years.
