Solder pressure ratings

in THE MAIN WALL
Does anyone happen to know the pressure rating of 95/5 soft solder. I contacted the manufacturer (Canfield), and they didn't have a clue. Using 2" copper w/approx. 200psi condenser water (80-100 deg. F.)!

    See...

    Nibco's engineering info,

    http://www.nibco.com/dl/coppercat.pdf

    particularly the table on page 46 with data for 1/4" to 12" copper at various temperatures using 50/50 tin/lead, 95/5 tin/antimony (about 2-3 times stronger than 50/50) and braze (where the tube strength is less than the braze strength).

    They don't show 96/4 tin/silver, but Canfield lists their 96/4 as having a shear strength of 180% of the shear strength of their 95/5, so the tin/silver solder *may* be as much as 1.8 times stronger than the antimony solder.

    a product you might want to look into is stay-bright. I have used this on a/c systems,high pressure/ high temps.stay-bright #8 sounds like the roll you may need. hope this helps. jb p.s. I think wolverine products makes this.

    is a 96/4 Tin/Silver alloy (3.6% silver, balance tin), 430°F melting vs 464°F melt for 95/5 tin/antimony. May be a little stronger than 95/5 too. Note Harris does not recommend 95/5 for soldering to brass.
