Copper pipe soldering limit
(OP)
Hi,
What is the largest copper pipe dia. that is commonly soldered? How is 4in. and 6 in. copper lines in domestic and in mechanical systems connected? Flaged, threaded or soldered, or other means?
Thanks,

We still have considerable Cu water piping in the 3" and 4" range that was soldered with tin/lead solder. This upsets the ESH people no end. The lead is non detectable in the water at present so I guess we consumed it years ago.

I was involved in a incident investigation regarding the filling of Dewar's at the storage tanks by a lab technician. It was when they modified the local draw off station that I discussed the brazing of the Cu with Sil-Fos.
I'm pretty sure that all pipe in the high side of plant is SS.

If it's a brazed aluminum exchanger inside, this is what it looks like naked, in case you're curious:
