Speedfit fittings and chrome plated copper pipe

[Willbeforced]

I've just discovered that you need to remove the chrome plating from the copper pipe before fitting the speed fit joint, is this correct??

If so, then how do you remove the chrome plating without damaging the pipe??

Hope someone can help.

Cheers

You raise an interesting point, but where did you discover this? and was any reasons given? Is it suggested it won't form a water tight joint?

As you know the 'seal' is made by a 'O' ring and it does depend on a good smooth surface finish where the pipe contacts the ring.
The chrome pipes I've seen all had mirror finishes and every bit as good as unplated pipe. Also I can't see the chrome having any adverse affect on the rubber 'O' ring.
To me there are only two ways of removing the chrome. One is chemically stripping it and that I feel would leave the surface pitted.
The other method would be by mechanical means. You could try 'wet & Dry' used in the form of a strip to get radial motion. You don't want any longitudinal scratches.
I cannot recall the thickness of chrome plating, but it is very thin probabley less than .001 ins. so it shouldn't need much energy to remove it over 1/2 in, which is what you would need .
I'm not convinced that it needs removing but others may think differenly.

It is a problem with all push on fittings because chrome is so hard the little metal grips cannot dig into pipe so when the pressure is turned up you get a very big leak as the fitting blows off the end of the pipe

The chrome will come off easily with a decent file

I always use emery cloth, it takes a little longer than a file. but the finish is smoother (less chance of damaging the o ring).

Thanks for everyone's help on this, most appreciated.
My bathroom floor is about to be sealed with floor tiles so it would not have been good to have found a leak later!!
