We have a 6-inch Schedule 10 main being hung with a trapeze hanger. The span on the hanger is 6-ft.
We're using a 2-1/2 inch Schedule 40 pipe as the trapeze.
Does the 2-1/2 inch hanger rings and rods with beam clamps need to use 1/2-inch diameter rod, since it is supporting 6-inch pipe, or can it use 3/8-inch hanger rings and rods?
NFPA 13 2016 Section 126.96.36.199.5 states "all components of each hanger assembly that attach to a trapeze member shall conform to 188.8.131.52 and be sized to support the suspended sprinkler pipe." Table 184.108.40.206 shows pipe sizes up to 4-inch require a minimum 3/8-inch rod and 6-inch requires a minimum of 1/2-inch rod.
Thanks in advance.
