You own a Ridgid 1215 with a reamer mounted right on the carriage and you don't use it? :think2:

I ream every piece (unless I forget)! I don't want to be the fastest just the best! I saw two guys get fired for not reaming. I am still working on the best thing and I will let you know when I am close.

Was told that it is imperative to ream when assembling the boiler in a mechanical room set-up. Go with the flow!

wait till you have a couple thousand feet of pipe installed and the inspector catches you not reeming your pipe and makes you rip it all out

I'm like birddoggiest - I ream every single cut.

Is there any test data available that provides data about the service life of reamed and unreamed copper pipes?

Cutting pipe with a saw almost eliminates the internal ridge caused by a pipe cutter but it can require a little filing to clean up the pipe after it's been cut with a saw or a grinder. Are there any issues with using a saw to cut the pipe?

so, how does all of this effect pex with insert fittings?

 Re: reaming pipes

I assumed that the water circulating, especially in hydronic heating situations, increased the wear and tear on copper but PEX when used with EP (engineered plastic) fittings nearly eliminates that.

It doesn't eliminate the turbulence but plastic doesn't erode from it like metals do.

Turbulence, there you go. That's the word I was looking for. :nerd:

 Re: reaming pipes

plastic fittings have to be thicker than copper ones so the velocity has to increase as it passes through them increasing turbulence and resistance.

But plastic being a soft resilient material doesn'r erode.

Correct, it just snaps off when stressed.

Yup! There probably is no perfect material...
Personally I like that!
My lifestyle would suffer if perfect materials were used! :laugh:

I think steel would be more resiliant to turbulance than anything.

IPC requires the pipe to be reamed.

"I think steel would be more resiliant to turbulance than anything."

No its not...
In fact Water Jets are capable of cutting many industrial materials including stainless steel, Inconel, titanium, aluminium, tool steel, ceramics, granite, and armor plate.[science.howstuffworks.com]

A few years back I was out fishing with a friend of mine on a very unique custom built sportfishing boat 60'+... 60 MPH + and we lost a prop. The broken shaft was sent out for analysis to find the reason for failure. The shaft was some fancy expensive alloy that was just right for the application but the lab determined that at the failure point there was cavitation erosion that weakened the shaft at that point causing failure. A different shape had to be machined in that area and the prop shaft failures went away.

i install fire sprinklers and i ream every pipe i cut. I don't think it really helps the life of the pipe at all for black pipe any way. I was told it is more for the flow.
