No, it will not affect them
YOU thread or braze copper pipe Copper tubling you solder, braze, flaire, compression ring, mechincal joints
Copper tubing solder "Solder" is an erroneous term as solder mean lead which of course is banned (safe water drinking act) Sweating is another term for "soldering" Copper can be joined by various alloys such as 95 % tin -5% Anatomy or one of the many silver bearing types of low temperature alloys. For the strongest possible joints brazing is the best way to go with a tensile strength over 87,000 PSI compared to soft solder joints of 16,000 PSI For DWV copper joints one can use one of the lead tin solders such as 50 -50 as it is quite easy to work woth.
Arthur R Maupin has written: 'Strength of soft-soldered joints in copper tubing' -- subject(s): Copper Tubes, Solder and soldering, Tubes, Copper
Solder is a low melt metal that is conductive of electricity, ideal for forming joints in copper wires, and other electrical devices, etc.
It is an alloy of copper.
Soldered joints will have a higher resistance if the joint is not a clean solder joint. Badly soldered joints are classed as a cold solder joint. <<>> ...for what? Application matters here.
Copper colored solder can be found at http://www.beadmeus.com/coppercolorsolder.aspx the flux is included in the soldering rod.
Depends on the solder used. If silver solder is used it is actually stronger than the pipe itself.
Depending on how many bars of pressure you are talking about and where you live in the world. But generally, copper or galvanised are good options and be sure to use copper compression fittings on the outside and solder joints on the inside if using copper piping.
Sandcloth the end being soldered. Squish the end with pliers so it is tight. Put flux on the end and solder. Easier to buy a copper cap and solder that on!
Yes
you solder or braze it
