Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa

Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa

Strictly speaking: the outer pipe network and the internal pipe network are the same. Minimum fire 1.0MPa, minimum sprinkler 1.4MPa. Because not only in accordance with the water pump, but also take into account the pressure on the fire engine.

To your selected fire pump highest lift 1.5 times to suppress, generally not more than 1.6MPa, if the use of ductile iron pipe, test pressure according to 2MPa to suppress.
