What can one use as a sleeve for 22mm Copper pipe? That's 22mm OD. It should be plastic, but I don't see anything of nearby size.

If it is to sleeve a section passing through a wall then 32mm waste pipe will do. I have seen Climaflex type insulation used, downside it requires a large hole but offers an air tight seal around the pipe.

ISTR that I have used 22 mm "speedfix" pipe, also some of the flexible
electrical conduit is a similar size.

How about:

FloPlast PEX Pipe 28mm

Or, possibly a bit too wide:

Solvent Weld Waste Pipe 32mm

32mm waste was the next size up I could find. But it's huge, it would require a very oversize hole in a tight space, and the space between the 2 pipes would need packing with I don't know what.

21.5mm couplers are very close. But, you guessed it... 0.5mm too tight! I wonder if I could get a 22.5mm drill bit.

Turns out I can, 23mm for a fiver off amazon. Maybe I'll take that option if I can't find the right pipe.

25mm PVC conduit might take 22mm pipe and you should be able to get a 25mm diam. drill easy enough.

DOH I meant I have used 22 mm plastic water pipe for 15 mm copper. I
think I have some plastic conduit which is slightly smaller than 32 mm
waste and which does take 22 mm copper. Sorry.

I'll check that out, thank you. I'm not confident the wall will be thin enough but maybe it will

yes... is it wise to go for such a close fit?

I was thinking that would be a bit tight :)

Looking at the 25mm electrical conduit (white plastic) that has the aerial
cables in, it looks about 1mm wall thickness and so 23mm ID.

On the pipe, doesn't matter; for the drill I'd want at least 26mm+sodslaw
extra.

28mm copper is the normal option when say taking a gas pipe through a wall.
