(65 mm). Hangers need to do three things: connect to the building itself, typically to structural members; be long enough to reach the pipe they are supporting; and securely attach to the sprinkler system piping. Specifically, NFPA 20 requires a pressure-relief valve inthe discharge piping where a total of 121% of the net rated shutoff (churn) pressure plus the maximum static suction pressure, adjusted for elevation, exceeds the pressure for which the system components are rated. In addition, NFPA 24 addresses how the pipe and fittings are to be joined together, depth of cover if the pipe is buried, protection of the pipe from freezing and other damaging events, joint restraint, and acceptance testing including flushing and hydrostatic tests. Nonpotable Water Sources for Fire Fighting, 15 . Prevention of overpressurization is therefore accomplished by altering the speed of the driver. Your writing skill is also very well.
