Pipe cutting optimizer

Steel pipe, copper, PVC, conduit, scaffold tube: enter the lengths you need and the lengths you can buy, and it works out how to get them from the fewest sticks. Free, no account, and the blade width is not an upsell.

Cold saw 2 to 2.5 mm
Plasma 1 to 3 mm

A wheel cutter rolls the pipe apart and destroys almost nothing, so kerf really is near zero. A saw is a different story. More on kerf.

Diameter does not enter into it

This is a length problem. Wall thickness, bore and schedule decide what you are cutting, not how to cut it up: run each size as its own job, because a 50 mm run cannot come out of a 25 mm stick no matter how good the plan is. What the optimiser does is decide which stick each length comes off, and how many sticks you need to buy.

Fit-up allowance belongs in the length

Sockets, couplings and welded joints eat into the run. Enter the cut length you actually want off the saw, not the centre-to-centre dimension off the drawing. The optimiser is precise about the material it is given, which is only useful if the numbers you give it are the ones you will cut to.

The offcut bin, and the stubs in it

Enter the offcuts you already have and the plan will use them, either first or only when they save you a stick. Set a minimum useful remnant so it stops leaving you 60 mm ends: below that threshold a leftover is not stock, it is a thing you have to bin. More on offcut waste.

FAQ

Should I set the kerf to zero?
Only if you are cutting with something that removes no material: a snap cutter, a wheel cutter, a guillotine. For any saw, measure the slot the blade leaves and enter it. A plan built on a zero-width blade is not an optimistic plan, it is a wrong one.
Can it do mitred and angled cuts for fabrication?
Yes. Give each piece its end angles and the material width, and matching mitres are nested so one cut makes both faces. The extra material an angled cut consumes is accounted for.
Does it work for conduit and cable tray runs?
Anything sold in sticks and cut to length: conduit, tray, ducting, scaffold tube, handrail. If the problem is 'which stick does each piece come off', this is the tool.
How many parts can I do at once?
Up to 5,000 parts a job, with no account. We have run a verified 960-piece job, and the plan is checked against your inputs before you ever see it.

Every plan is checked before you see it

Cut by cut: every piece present, everything inside the bar, blade width included. When the green badge shows, no plan on earth uses fewer bars for your cuts, and we publier les jobs that prove it.
