Fire sprinkler orifice size chart
WebThe K-factor is a “constant” that expresses the flow performance of the sprinkler head. It is determined by the size and shape of the internal waterway and water exit orifice (bore diameter). Sprinkler K-factors are internationally standardized: K57 is the smallest and normally the standard in 10mm sprinklers . WebHD FIRE PROTECT PVT. LTD.
