i agree-i have heard/seen but not felt a pvc explosion at a shop i sued
to operate out of(leased) pretty amazing! i mean it blew the fitting
60's across the shop with a BANG thank goodness i was wearing my
hearing protection!
steel=rust which can be prevented with a drip leg and drain cock at
every drop combined with .25/foot drop/rise in each horizontal
pipe(think black sewer pipe regs)
copper can be ordered in thickwall-not plumbing copper but the stuff
used in freon lines-it can take 350+# all day-i do HVAC so have
installed up to 2.5" copper freon lines for commercial apps. it must be
welded with sil-fos which is NOT standard plumbing solder. its
silver/brass alloy and is for the high-test lines. actually i think
that stuff is rated for over 600#-it has to the new standard is 410a
and it runs at 350-400# all day on the high side. keep in mind-the
thick copper with the required sil-fos is expensive and also MUST be
welded with a torcch-not a plumbers propane torch-it MUST BE dual-fuel
oxy/act torch or oxy/prop. plumbers torch doesnt get hot enough. and
for the big 2+ stuff you need a rosebud and helper makes life easier.
i had herd-rumour? that there was a pvc in production specifically
rated for high pressure air. true? if so-its not what you find at
lowes-box store.
