How much solder for 15mm pipe?

[JohnMalcolm]

Hi All,
I hope you are doing well.
I have this 3.25mm lead-free grade 99c solder wire. I know that the good practice to bend the wire before soldering so you know exactly how much it is absorbed by the flux. I know too little isn't good and too much is as bad.
I need to connect two 15mm pipes with a straight connector.
Thanks

They used to say the same dia the same length of solder eg 15mm tube 15mm long of solder

ok so I bend 15mm of solder then I know flux has sucked enough of it.
If I do the connector should I do both ends at the same time?

So I bend twice 2x 15mm.

Yes front then back etc and yes

Just use a Solder Ring fitting if you're not sure or confident.

15mm for 15mm copper as above, but important to make sure it flows completely around the circumference.

Let the heat of the metal melt the solder (not the flame).
Apply solder at the base (lowest point) so you can see it flood the fitting.
Don't burn the flux.

Practice makes perfect!

You sure about that. Obviously, like I assume all the pros on here I don’t measure solder but wasn’t it half the diameter up to 28mm pipe?

15mm for a 15mm pipe is loads and will be dripping off the bottom.
