cutting 15" diameter pipe

[txrpls]

Any of you experts have any suggestions on how to set up a guide on 15" diameter pipe so I can cut off a couple of 12" sections. Tried fee handing and I am not worth a darn. I am using a Hypertherm PM 45. Some kind of strap for a guide?

a pipe wrap, soap stone, mini grinder, and cut off wheels. i use pferd #69963 (.040 x 6") for pipe, i can cut a 36" pipe .375 wall in 30 minutes, w/ a 13 amp mini grinder. itll take 3 $5 wheels. beautiful results

If you have a good and to start with cut it from the inside with a length jig... but I'm guessing you already tried to cut so the end is probably a bit jagged

Normally I'd just mark it with a sharpie or chalk by using at least a 1 foot wide piece of cardboard or something else with a straight edge, flexible and long enough to wrap it... you gonna need a bit over 4 feet long but 4 would be close enough to get it straight, just tape the center of one end on the pipe and wrap it...

you said it. a strap to slide over the pipe. easy.

How long is the 15" pipe ? Is there one good end ? Set pipe upright in flat surface and cut a 2x4 to required length to use as a guide to rest plasma on.

Do you have a metal supplier or fab shop nearby with a 16x24 bandsaw or larger?

They could square your end and cut two nice sections in little time.

The guide for that size pipe will set you back some https://americawestdrillingsupply.com/TorchGuides.asp . A pipe wrap around and soapstone is how i would do it

Thanks for the tip. I only have a 4.5" angle grinder, but cut it off using 4 wheels.

Crappy but dirt cheap guide is plumbers tape pulled tight with a nut and bolt

if not comfortable with soap stone as a guide, then use an HF ring roller to roll a ring to fit the pipe. use a drag tip. you could form 11g x 2" fairly easily by hand.

I like that idea

my mini grinders are 4.5" also. it just seems hard to get any work done w/ 4.5" cutoffs wheels. if your not used to them, maybe best you use the .045 x 4.5 " w/ guard. the part # of the 6" wheel i gave are more flexy/squirrlier than most ,(take some getting used too) but they cut like a mother ****er.

Wish I had bought some of them in the day, trying to cut vertical casing near ground level was always a pita with a wrap on the larger sizes. And standing on your head didn't help.
