Wall thickness of copper tube?

[wetdrip]

Guys, is there any difference you've noticed in the wall thickness of the copper that you buy?

I have no idea to be honest, never pay attention to the pipe, to busy making money off of it 🙂

 

[bassmonster]

all i know is that you have the black label and blue label.....

I know I bought some that was on offer at a well known shed and realised later that there was a marked difference.

If you buy kitemarked table X from a reputable supplier, it should always be the same...

SHOULD is a funny word though, isnt it?

 

[WaterTight]

the real difference is between old and new.

cutting through imperial 3/4" you almost need to take a break halfway. a new length of 22 takes about one turn of the slice.

...which i suppose at least saves on time on installation.

...valuable microseconds that you can better spend staring into space, scratching your arse and wondering what's for lunch.

Weight per metre lenght might be a clue !

So true.

I try to buy British copper but had some foreign copper years ago that wasn't good for bending. Some of the 28mm would snap in two in the bender.
Think ordinary copper is supposed to be 0.7mm thick?
Cutting 3/4" copper with pipeslices is not always easy as the pipeslice is for 22mm.

I had 0.8mm in my head...

I had a quick look online about Yorkshire copper & it reads that table X in 15mm pipe is 0.7mm thick & 22mm or 28mm is 0.9mm thick.
Guess it makes sense the bigger the diameter the pipe, the thicker the wall ideally it needs.

0.7 15mm
0.9 22/28

Think this may be the answer,

Many THANKs Ermintrude , little did I think TABLEs and not think maths X Y Z zzzzzzz

( Super thin stuff not made to bend ! )

Yes a lot of supplied copper tube is crap with thin wall -

but it all depends whant you want to do with the tube

1. poor stuff will not swage or bend with springs and maybe not go around 90deg
corners with a bender
2. if your just doing straight lines and doing the rest with fittings crap stuff is ok

Horses for courses hey

I know that the cheap stuff doesn't always bend nicely. I try to get the decent stuff if I can.

Yorkshire kuterlon is much thicker, but you have to order it specifically

I used to apply small finger adjustments to 28mm tried a small offset on some Lawton and it kinked... Did it on some black label and she's a beauty. Ps a finger kink is adjusting the route of the pipe without the aid of bender or springs - works upto 30 degrees.
