Cutting corrugated plastic pipe

[echoechoecho]

Hi chaps,

 

What's the best way to cut 600mm/24in diameter corrugated pipe - chainsaw, reciprocating saw, jigsaw, circular saw or grinder?

 

I'm picking up a 6m length next week but I'll have to cut it in half for it to fit in my van.

 

Thanks

Angle grinder.

They will all do it, some being more difficult than others ie jigsaw. And some will be smoother finish. I would personally go for the skil saw ( Circular saw) I’ve cut those 200lt blue drums in half with an angle grinder and a diamond stone cutting disk it left a nice smooth finish and lots of staticky charged bits a mask would be worth wearing unless the wind is in your favour, and it was slow. the stone/ metal grinder disk just clogged up. 
 

but if your really pushed you could just as easy do it with a good hand saw

 

let us know how you do it and your experience ??

We only use a fresh cheap hardpoint for cutting plastics, as long as you dont allow it to pinch its easy work.

Thanks for the advice.

I've cut plenty of soil pipe and 4" land drainage with a hand saw, but assumed the wall thickness of the larger pipe would make it slow going.

I'm replacing an old stone-lined culvert with 24" corrugated pipe as a section of the roof collapsed during particularly heavy rain in late February, blocking the stream. The water was lapping up at the house and threatening to flood my workshop.

I cleared the blockage as soon as the water level dropped, and for the last 3 months we've had a big hole in the garden.

Cheers,
Mark

we cut that pipe with a chainsaw and have done for many years now, it wont do any harm to anything as it is a relativly soft plastic,

Chainsaw all the way. Plastics should be cut with teeth, not abrasives. As mentioned abrasives will just clog up. Type of plastic matters- you can get away with a chainsaw easily on soft twinwall, but you're liable to shatter a 110mm pipe using the same.

 

The metal cutting blades in a circular saw make a nice job quickly of harder plastics as well as larger things like barrels. The teeth have much less rake compared to a wood blade, plus a raker like a chainsaw chain so they don't grab.

I took both a chainsaw and reciprocating saw with me when I went to pick up the pipe on Tuesday,
but it cut easily with the recipro saw and fine metal blade. I tidied up the edge with a flap disc afterwards.

If only laying the pipe was as easy - machinery would have made short work of lifting some of the larger stone slabs out of the trench, but it's been interesting having to improvise with a homemade crane, straps and a come-along.

I've cut and spun them with a tenon saw, drainage is hard graft. Should have listened more at school...
