solder psi pressure?

[spud-tom]

If i get 2 pieces of copper pipe and put a s h i t load of solder properly to the joints, how much psi can it hold? maximum

[hi]

well ive taken ie to 135 with no leaks or problems of any kind. im sure it can take more than that thogh.
also, it isnt about putting a ton of solder on, its about doing a good job.

Actually, too much solder just clogs up the internals of the joint, so it needs to be done sparingly.

With a properly cleaned and fluxed joint, done with a fairly powerful blowtorch (a pencil flame one will not produce as strong a joint), and done carefully, you should easily be able to put 300 psi behind joints up to about 1" in diameter.
Beyond that, you might still be able to do that pressure, but you'll really need a proper blowtorch for it.

Well put Joanna.
Iv'e seen auto repair shops run copper air lines. Basicly 150psi for months on end, so it's long lasting also.
