Specifications
1. Material: Cast Iron;
2. More than *0 designs for fire cabinet;
3. Directly from China largest fire equipment manufacturer.
A hose is attached to the fire hydrant, then the valve is opened to provide a powerful flow of water, on the order of **0 kPa (*0 lbf/in²) (this pressure varies according to region and depends on various factors including the size and location of the attached water main). This hose can be further attached to a fire engine, which can then use a powerful pump to boost the water pressure and possibly split it into multiple streams. The hose may be connected with a threaded connection or a Storz connector. Care should be taken not to open or close a fire hydrant too quickly, as this can create a water hammer which can damage nearby pipes and equipment. The water inside a charged hoseline causes it to be very heavy and high water pressure causes it to be stiff and unable to make a tight turn while pressurized. When a fire hydrant is unobstructed, this is not a problem, as there is enough room to adequately position the hose.
