Threaded steel (galvanized) water pipe is run horizontally. What is the typical maximum horizontal support spacing?
a.6 feet
b.12 feet
c.3 feet
d.32 inches
Giải thích
Threaded steel pipe is rigid and heavy, so the support table typically allows a maximum horizontal spacing of about 12 feet. 6 feet applies to small copper, 3 feet to small CPVC, and 32 inches to PEX, all of which are shorter than steel's allowance.
