Best tape or protection for copper pipes against plaster

[shd1970]

I’ve just completed a bit of 15 mm copper ready for my new radiator
The pipes are in a channel of Therma light blocks but do not come into contact with the pipes
It’s going to be plaster boarded over soon, so I’m looking at what type or protection to put on the pipes as a belt and braces to make sure they do not corrode

I see mention of duct tape as being okay but is it okay for central heating pipes, but also saw mention of this lagging that someone used and wondered whether that might be better :

I was just curious as to what everyone’s preference is and what you feel is best

TIA

Tape is fine.
I think because cooper expands and contracts the rubbing is more of a problem.
Where I live stones rub through copper pipe in the ground..
I've never seen cooper corrode and burst through. I've seen plenty that are green from corrosion that must be 100+ years old.

Thanks @Wayners
When you say tape is okay, you mean using something like duct tape or any similar type of tape ?

As you can probably make out from my other thread/photo that you have kindly replied on, you can see the original pipes that it looks like just has some kind of yellow plastic tape on
My concern about any sorts of tape like that certainly because they’re central heating they will crack due to heat and expansion
That’s why I thought that felt wrap would be a better solution albeit expensive for the amount I need

Id paint that will spray can or something.
I wouldn't worry about it tbh.

Yeah. Tape wont like the heat.

Some use foam to cover

Strips of thin corrugated cardboard wound round the pipes would allow for expansion/contraction.

A quality duct tape can take temps up to and in excess of 85degC before the adhesive starts to become compromised. So buried in a wall it should be fine

Would that be for prolonged periods though ie central heating use ?
There will be no actual thermalite blocks, concrete or plaster touching the pipes so not sure if I’m overthinking this but I just noticed that the existing pipes were covered in a yellow pvc type tape, I assume to prevent any possibility of reacting/ corrosion hence wanting to continue the same approach

Yes - CH typically won't run hotter than say 70Deg, even cooler if it adjusted down to a more efficient 60-65deg. The adhesive on good quality tape only has issues with prolonged temps in excess of it's working range so say >90deg.

That being said if the pipework isn't in contact with the plaster then just some felt will happily do the job.
