Really? Pipe clips

Fen1

Surely the new pipes to my my new radiator should be secured under the joists by a clip?

Presuming they've been run in afterwards, how could they be clipped to the underside? And would it make pipe replacement more awkward? (Disclaimer: I'm not a plumber.)

...and insulated.

I have no idea. That's why I'm asking. I'm genuinely asking for advice.

I've never seen a pipe clip designed specifically for that kind of installation.......but that doesn't mean one doesn't exist.
I would screw a clip to a small piece of wood then thread the clip onto the pipe, then screw the small piece of wood to the joist. I don't see another way of doing it.

Could be a good idea.

I'm suffering knocking after the heating being on 2hrs or more and the claim is 'pipes banging against the clips as they expand.

Jury;s out on that one but

They have to be fixed, but why clipped and why under?
Insulated - yes.

What material are the slings made from?

Either a cable tie, or one of the plumber's bootlaces.

The problem is actually getting room to swing a hammer or get a screwdriver in the floor void to fix the clips to the underside of the joists.

I find thin galv. steel straps are very useful to fix things where there does not seem to be a purpose made fixing available.  In this situation you would cut off a length of the strap and twist each end through 90 degrees and bend the middle of the length of strap under the pipe and simply nail each end to the side of the joists.  See link below for strap:

The strap can be easily twisted with two pliers or pliers and a vice and cut with tin snips as it is only about 1mm thick.

I used to have pipes that made a very loud and annoying ticking sound as they heated up & cooled down. When I redid some of the plumbing, those two pipes got sleeved in 20mm plastic conduit that was in turn fixed to the wall. No more noise.
