CORROSION RESISTANCE RATIO (CRR)
The CRR is a ratio value used to measure the ability of a pipe to
withstand corrosion. Schedule 40 steel pipe is used as the benchmark (value of 1.0). The
average CRR values shown below are higher than other similar lightwall steel sprinkler
pipes. The following are
the specific values by pipe size:
