securing copper pipes

[alec green]

Hi

I had some mild steel brackets holding some copper pipes in place on a
wooden joist, but a plumber told me that I should not use mild steel
as it reacts with the copper, but I forgot to ask him what I should
use. Any ideas Please.

Thanks

Alec

Or just put something nonconductive and nonsaturable between Cu and Fe, like a bit of plastic from a drink bottle.

Dear God, it's him spouting more of his bollocks.

Plastic pipeclips from any DIY shed or plumbers' merchants. The steel only reacts with the copper if they're wet, usually condensation forming on a cold pipe. If it's not wet it's not a problem.

If it's an old installation and there's no corrosion, there's not a problem that needs fixing.

indeed

If it's not wet it's not a problem.

if condensation happens later, it is. Corrosion between different metals can be quite fast. A slip of plastic solves it by blocking conduction path, either metal to metal or via condensate. If you don't know this stuff you're a fool for complaining.

You (and the OP's plumber) neglected to mention the magic, missing ingedient for a corrosion cell, i.e., Water.
Or an electrolyte , to save you trying to be pedantic.
You also neglected to mention the obvious simple fix, plastic pipe clips.

Cut up drink bottles. FFS. That'll look reet posh.

You come across as a dullard trying to talk the talk. Give it up, you haven't a clue.

Just to clarify that, for the seriously stupid. It's either a cold water pipe (mains, CWDS) on which water vapour may condense, or it isn't (heating, hot water, gas).

And of course, what is intended as a hot water pipe might not always
actually be hot. So it too might have condensation forming on it. Whether
it is a heating pipe or hot water. Indeed, such pipes might get pretty
darned cold under some circumstances.

They're not always ideal. If running a hot water pipe mounted from above -
like say in a cellar - they can sometimes pop out due to expansion and
contraction. Copper saddle types are better for that.

No, I mentioned it, after initially assuming people would know about it.

water plus dust soon makes that

slipping a bit of plastic in is far quicker than goping down the shop

The OP has copper pipes on steel brackets. So most likely this is in a location where appearance doesnt matter one iota.

same dumb responses as always

Fact: what I mentioned works
Fact: sometimes its mcuh quicker & easier, sometimes its not whats wanted.
The rest is hot air

You mean a pipe intended as a hot water pipe may have cold water running through it?

I'd suggest you get your plumbing looked at.

It has to be below the dew point and a hot pipe cooling towards room temperature wouldn't do that.

I'd use the Talon plastic ones with the snap closure.

Nigel, you're an ignorant dullard.
Try and spin it as you may, you left out all the relevant information.

Bore off.

Can one not simply put some form of tape or other substance between them.
I'm sure I've seen this done..

Yes, I do. Happens all the time - you know many properties do not have the
heating blasting away every hour of every day! Like timer controls, and
thermostats, and even being manually switched off when people are on
holiday.

What is room temperature? In the winter it can drop pretty low.

He's right about the mild steel.

You can buy a range of copper saddles and plastic clips for the job.
You can wrap some electricians plastic tape round the pipe but it's
quite fiddly to do this.

These are particularly useful if you have odd surfaces to mount to as you
can make them stand off pretty much as far as you like.

That would do it. Not seen them in the sheds - but then I've not been
looking.

Yes, and the air moisture content drops as well. You still need a pipe that is cooled for
persistent condensation. I can't see it happening.
Rod? Speed?
