Use the Pipe!
AWWA M11 table 7-1 Practical safe spans for simply supported pipe in 120
degree contact saddles, allows a 24 in diameter pipe, 1/2" wall will span
60 feet; 18" dia. x3/8 will span 52 feet; and a 10" dia. pipe x 5/16 wall
will span 46 feet.
Until you get the stiffness of the beam up the pipe will support the W8

I have a W8 x 24 that is intended to carry a 10" water line for fire
protection. The problem is the beam is spanning 60 feet! After hearing
this from the contractor I told him there was no chance that the beam
would work (he called me as the Fire Protection contractor was about to
start hanging the pipe). What I am trying to do is determine how it can
be reinforced (not necessarily in place) to support the load. The
building is a Metal Building and the top flange of the beam will not be
braced. Any ideas?
