Soldering chromed pipe
Andrew Gabriel
Looking to make a join with an endfeed fitting rather than a bulky
chrome compression fitting, which I might try painting silver afterwards.
I presume you have to strip the chrome to do the soldering, but does
the heat wreck the chrome further back up the pipe? (I don't have a
piece to hand to try it on, or I'd answer my own question.)

You don't have to strip the chrome fully - but abrading it helps. I've
never done it on a joint in view, but as far as I recall, the chrome
gets a bit rainbow hued for about 1cm max from the joint - other than
that, it is unaffected. I don't know whether it would polish out
again.

The heat doesn't wreck the chrome, but it can turn it a little blueish
or brownish, while still leaving it shiny. A gentle rub with some
chrome polish (Solvol Autosol) is usually enough to restore it.
It is worth shielding the pipe to keep any discolouration to a
minimum.

I have serious doubts as to whether the solder will really work properly.
Soldering actually alloys itself into the metals being jointed. (I recall
sectioning and polishing samples at college) Chrome wouldn't alloy to the
solder - you may end up sticking the parts together - but it won't be as
good as solder on copper (IMHO).

Well don't do what a British Gas - gas fitter did in my parents home
some years ago...
He tried to solder a copper fitting onto a chromed copper pipe without
taking the chrome off first. Of course the solder never wetted the pipe
at all and later the pipe worked its way out of the fitting causing a
gas leak. Strip the chrome off back to clean copper with abrasive and
you will be fine.

Thats what I did in my bathroom to use chrome on the rad tails and the
joint worked fine .

Poor quality chrome can flake, due to differential expansion, but otherwise
there should be no noticeable effect, unless you overheat it. The best way
to strip the chrome off is to heat the pipe gently and dip it in
hydrochloric acid. Naturally, this is something that needs to be done with
care and with suitable protective measures, but you get very precise control
over how far it is stripped back and a neat line between chromed and (very
clean) non-chromed bits. Solder as quickly as possible after dipping for
best effect.

You can't.

My experience with chrome is you never get the stuff off, or it comes
off in huge ugly flakes.

That is a valid point, but with respect, Andrew said at the outset
that he would be removing the chrome plating from the end of the
chromed copper pipe so that the solder would take.

You'd probably be better off using stainless steel rather than
chrome-plated pipe.

As long as you abrade it enough to get some copper shining through in
the troughs of the scratches, the solder will take well enough in my
experience. Having said that, it's only four years and counting since
the first one I did, so there would be ample time for premature
failure. It seems easy enough to tell the difference between one
which hasn't worked (the solder doesn't wet the joint properly at all)
and one which has.
Bruce
How well does solder take to stainless steel? That's a genuine
question, because I have never tried it.
The Natural Philosopher
It's probably the chrome in the steel...;-)

Hey, I believe you are thinking of welding where the weld alloys with the
parent metals, in soldering however, the temperature used is not high enough
to melt the parent metals so only the filler metal will be melted. Aside from
discolouring, solder should work on the chrome

“it should be clear by now to everyone that activist environmentalism
(or environmental activism) is becoming a general ideology about humans,
about their freedom, about the relationship between the individual and
the state, and about the manipulation of people under the guise of a
'noble' idea. It is not an honest pursuit of 'sustainable development,'
a matter of elementary environmental protection, or a search for
rational mechanisms designed to achieve a healthy environment. Yet
things do occur that make you shake your head and remind yourself that
you live neither in Joseph Stalin’s Communist era, nor in the Orwellian
utopia of 1984.”

This is after I assembled some solder joints which just blew apart under mains pressure.
'Twas years ago, maybe fluxes have improved.

they would be halfway through the life of the O-rings by now.
I generally design my plumbing installations to last longer
than the lifetime of pushfit couplings.
It's not smart to design a plumbing installation that is
likely to fail in my old age.
Second issue is that the chrome is very hard, and the grab
rings often fail to bite into it, and the coupling comes off
some random time later. So you should strip the chrome for
pushfit fittings too.
Third, I'm using chrome to make the installation look nice.
Why would I spoil that with bulbous pushfit fittings?
On appearance, I wiped solder over the outside of the end-
feed couplings whilst soldering them, and then they blended
in with the chrome pipe.

not sure about the lifespan but after ten years (shower install) they seem to be OK.
Techtite make no mention of a lifespan but I'm strictly an amateur so only speaking of one experience, maybe ignorance is bliss?
The post is as you say 10yrs old (I didn't notice that) so it's a moot ponit now.

too rather than a 10 year old post (like I’ve just done).
