in this video we are going to look at deburring
some copper pipe when you cut copper pipe especially using a pipe slice you
tend to get a internal Burr which needs removing if you don't remove that you
can actually get turbulence within the pipe and that can cause pinhole leaks
Etc from erosion so I'm just going to cut a short piece off this
and if you look there you should be able to see the internal Burr the outside of this doesn't have
a burr at all because we have used the pipe slice you can get a couple of deburring tools this one
is specifically designed for copper pipe that has an internal and an external part for deburring the
pipe they are okay but they're not brilliant you can also get one like this which is a deburring
tool and these are absolutely brilliant I used to have one of these in my toolbox when I work
on site the beauty of these is they will work on steel pipe Etc sometimes when you cut in the steel
pipe you will use a dedicated machine for that and that will always have a deburring attachment on it
so to remove the burr from that it's very simple as we do is take the deburring tool
and we simply run that around the inside of it
so if we look down there now you can see that there is no burr so I'll demonstrate
to you why it's important to remove the Burr if you don't remove the burr you can
get turbulence within the pipe and that can cause pinhole leaks in the pipe Etc
just by looking at this you can see that the water is traveling much further with the Burr on the
pipe and obviously that is not good for the pipe because these turbulence within the pipe which
can cause premature wear if you don't use a pipe slice and you use for example a hacksaw you could
get external Burrs then in which case you would need to deburr it externally if you get a piece of
pipe and it's in situ and you need to deburr that obviously all the copper is going to fall inside
of the pipe I did think about making something that pushed in the pipe that was tapered that you
could pull out that would remove the bits of swarf but I actually went to B&M Bargains in Blackburn
and I actually found a set of these and they're two pound fifty for two and these are drain Grime
removing brushes and I saw them and I thought they would be absolutely ideal for this purpose
so if you ever go to B&M Bargains it's absolutely brilliant they actually have staff that work in
there on the tills so unlike some supermarkets so they're doing all the self checkout nonsense
you can actually go into B&M Bargains and you can get served by real staff obviously we don't need
the full length of the brush and the good news is these have actually been reduced in price
to a pound for two now but you might have to be quick so we're just going to snip the end off that
because we only need a couple of inches of this
I'm just going to use some Aviation Snips for that and I'm just going to burn a bit of the nylon away
we don't want to make this too long if you try pushing the full length of the
brush down there it is very difficult to pull back out so we can push that into the pipe
and we're just going to go below the surface
we can then get the deburring tool
and we can deburr that
and then we can just take a pair of long nose pliers
and we can pull the brush out and that will bring any of the copper debris with it so if
you need to cut and deburr a pipe that's in situ one of these is absolutely ideal
