I have an 80m vertical using 3" irrigation tubing and a 160m vertical
using 4" irrigation tubing . The 80m been up since 07 ! To splice the
tubing , I use the same tubing and dado about 3/4" out ,then use hose
clamps to squeeze it tight so to slip it inside the long joints. To keep
the vibration down don't guy at the same intervals. Using the falling
derrick method I was able to raise both the 80 and 160 with the help of
a winch .
I made a short youtube video . It starts out with const. pictures then a
video of the 160 being raised .

Not only is irrigation PIPE thin, it is apparently soft. My internet search
for the aluminum grade showed it being made of 3004, This is what beverage
cans are made out of.
I had a 54' freestanding homebrew vertical in windy Aruba using 3" diameter
6061 tubing at the base and tapering to 1/2" at the top.

I know aluminum irrigation tubing has been used by many with success.
Personally, I don't like it beacuse the wall thickness is so thin.
