FIRE EXTINGUISHING SYSTEM

A fire extinguishing system including a fluid source, at least one sprinkler (2), and distribution pipes (3). The distribution pipes (3) are formed at least partially as soft-steel metal pipe having a friction loss defined according to the Hazen-Williams formula (1), with P=6.05·105·L·Q1.85·C(−1.85)...

More Information
Summary:A fire extinguishing system including a fluid source, at least one sprinkler (2), and distribution pipes (3). The distribution pipes (3) are formed at least partially as soft-steel metal pipe having a friction loss defined according to the Hazen-Williams formula (1), with P=6.05·105·L·Q1.85·C(−1.85)·d(−4.87), in which P=pressure drop in the pipeline, in bar, Q=flow rate through the pipeline, in l/min, d=average inside diameter of the pipe, in mm, C=constant for the type and condition of the pipeline, and L=equivalent length of pipe sections and pipe fittings, in m. The distribution pipes (3) have an anti-corrosion coating on the inside in order to ensure a value for C in a range of 125 to 150 during commissioning of the fire extinguishing system.
