I have a twelve foot long piece of galvanized pipe I want to use for a
mast. On the pipe is stamped in red "
" Wheatland cbw rn 1176 cbw rm 1504 astm A53 -f- gra 40 A 21 foo
32698 DI."
This has an outside Diameter of one and three quarter inches. It
just does fit through the rohn 2" thrust bearing... I want to use it to
mount a beam with a 4.9 square foot wind surface at the top of the
mast pipe which is sticking ten feet out of the top of a flat top
rohn 25 top section with the rohn thrust bearing on the flat top
and a rotor in the usual place. How much wind would it take to bend this
pipe?? Thanks Dick W5AA
